Audigy 2 Static when using DSP

Noyabronok · Mar 19, 2009, 02:03 PM

I have the kx drivers installed for my Audigy 2 Platinum on Vista 32bit SP1. I hear static even on a clean line. The only way I've been able to get rid of it on this card is by clearing the DSP, but then I loose control of the settings. I can reduce the static by removing DSP items such as chorus and reverb, but there is still some static left. Why is DSP causing static, and how can I remove it?

TravelRec. · Mar 19, 2009, 02:45 PM

What is the status of any incoming signals e.g. Line in / Mic in / CD in ?

Noyabronok · Mar 19, 2009, 03:34 PM

they're all muted, if that's what you mean

you are not really being very specific about how you are seeing this static...

With default DSP and seeing it on the Peak plugin...??

Or... you have all the inputs muted on the ins and outs page, and seeing static when using, and in, a recording applications record meters - in which case its the recording page that affects this - not the ins and out page.

What input - an AC97 one, or one of the I2S or SPDIF ?

is it even coming from an input? again assuming a default DSP (minus the reverb and chorus plugins), when you connect a peak plugin to prolog - is it observed there as well, or is it coming from FXBus?

Noyabronok · Mar 19, 2009, 05:03 PM

You're asking good questions. One of the things that I would like to do is figure out exactly where it's coming from, so that's why I've been removing objects from DSP and testing the sound after each change.

I have not gotten to testing recording yet, since the problem is reproduced on playback. The static (clicks and pops) is very bad with default kx-DSP (and Creative drivers that I was using before). Once I remove more and more non-essential items from kx-DSP setup, such as reverb, chorus, fx-bus, and such, the static almost dissapears from a clean line. Once I start playing a movie, using media player or VLC, or even doing the Vista speaker test, the static can be heard (although not as bad as default DSP). The kx speaker test always fails by the way, says can't generate sound (i'm guessing that's just a kx bug).

I have an on-motherboard 7 channel sound chip in the same computer that has absolutely no static with the same set of speakers, and the Audigy card used to work fine in another computer running Windows XP.

I really wish I had a better way of figuring out where the static is coming from exactly. What would be your next suggestion?

Maddogg6 · Mar 19, 2009, 06:36 PM

OK - Vista...
But Vista support is still a work in progress.

and particularly with ram > 2GB (for many, but not all)

Was the OS the *only* thing different - or did the computer hardware change as well (added ram for instance)??
(> 2GB in XP was a problem too if I recall correctly)

You can try increasing the 'playback buffer size' in kX Settings > Setup Buffer....

Revert to WinXP ??

Noyabronok · Mar 19, 2009, 06:40 PM

Here is how much i was able to remove from DSP and still keep all channels going into 2.0 output (see attached picture)

There is very little static compared to default DSP settings, but there's still some. Again, if I clear all DSP the static will be completely gone, but so will my ability to control channels and everything else from the mixer.

Noyabronok · Mar 19, 2009, 06:52 PM

I have 4 Gigs or ram, with 512 mapped to on-board 8200 Nvidia chip. The entire PC changed, not just OS. New motherboard, CPU, etc. I tried increasing the buffer size, and that helped, but I still hear some static..

Also, when I increase the buffer size there is a noticeable delay with the video. Unless there is an easy way to sync video to this delay this is not an option for me.

TravelRec. · Mar 19, 2009, 07:16 PM

What happens, if you disconnect the surrounder from the epilog? Have you tried to use ProFX instead of standard plugins?

Noyabronok · Mar 19, 2009, 09:12 PM

I think I tried disconnecting surrounder before with no luck, but I'll try it again. Thanks for pointing me to ProFX! I'll give them a try and report back what I find

Russ · Mar 19, 2009, 09:21 PM

As already indicated, greater than 2GB RAM is currently not supported in Vista with Wave/Directsound, so as long as you are using 4GB, it is tough to provide help (since we cannot rule that out as being the problem).

Most likely the noise is not coming from the DSP itself, you should be able to confirm this by testing with one of the cards inputs.

What device are you using for playback? You should not get any sound playback without FxBus loaded, so it makes me wonder if maybe you are using WaveHQ (which I am not sure is supported in Vista currently?).

I suggest connecting peak plugins to FxBus (using Master Mixer as the playback device) and check the levels there. If the signal exceeds 0 dB at any point, try lowering the volume in your playback application or the windows mixer to a point where it no longer exceeds 0 dB (I suspect that it might be like +18 dB too loud, but it is just a guess), and see if it helps with the noise problem.

Yeah, I thought his pic / description was odd too, but wave HQ makes sense - in which (if suppoerted) the P16V (used for Wave HQ) can could be disconnected from the outputs in the 'kX 24/96 router' (and possibly could eliminate one source of noise..??)

Noyabronok · Mar 19, 2009, 10:36 PM

Ok, here's what I got. I removed surrounder and ran 4/5 directly, then 6/7, then 8/9 and they were all clean. I tried using a 5.1 to 2 plugin instead of surrounder and there was a lot of static. I tried the ProFx and got the same results. I'm attaching a picture so that you see what I'm doing.

So, my conclusion would be that this is due to combining channels, but I don't know why and how to fix it. Any suggestions?

Russ · Mar 19, 2009, 11:11 PM

Did you check the levels using peak plugins? If the levels are too high to begin with (due to a possible kX bug), combining the signals together will likely just make things worse.

Noyabronok · Mar 20, 2009, 12:02 AM

Here is what the levels are. I don't know what they should be or how to adjust them.

the attached picture shows one of the channels playing. I caught it during the "Master Mixer" speaker test initiated from the Vista "Sounds" screen

Russ · Mar 20, 2009, 12:45 AM

I do not see any problems there, but do those sounds give you problems/noise? If not, you should check the levels when playing something that does give you noise.

Beyond that, I do not know... I cannot think of any other reason why downmixing to 2.0 would result in noise.

Noyabronok · Mar 20, 2009, 01:37 AM

That last picture was taken of the speaker test, and there was static. Here are some questions/thoughts I have.

1. Does this have anything to do with latency, irq, or other PCI settings?
2. What about EMI? Does the DSP convert to analog when downmixing?
3. Maybe I should try a plugin that cleans the sound?
4. Since buffering has an effect on static, maybe that means something for DSP?

No, the DSP is all digital. There is no reason (given the above levels) why the signal would be clean from the SRC plugin, but have static after the downmix plugin, unless you are just noticing it more due to an increase in volume (or you are doing something in the DSP that is causing noise, etc (and none of the plugins that you are using should do that)). If buffering has an effect on the static, then it is something that is happening outside of the DSP (again maybe the RAM thing). Again, I would suggest testing using one of the cards inputs. If you are getting the same noise with the cards inputs (monitoring via the DSP), than I would look into other things, like possible grounding issues, or EMI, etc.

If the noise is only at a particular frequency, then you could try filtering it out using one of the EQ plugins (for example, if it was a 60 Hz hum from AC power, than you could try to filter it out using a notch filter set to 60 Hz, etc).

BTW: Playback using kX ASIO does not have the RAM issue, so you might also try playing your audio using kX ASIO (from an app that supports ASIO) and see if it makes a difference.

What's the status of your box? That is, is it a brand new build, OEM, or what?

What motherboard, sound card, and PSU is at issue here?

Noyabronok · Mar 20, 2009, 01:09 PM

I will try removing 2GB or ram and a few other things to see if that helps and let you guys know.

This is a custom built PC with following specs:
Sound Card: Audigy 2 Platinum
Motherboard: ECS GF8200A
RAM: CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066
CPU: AMD Phenom 8750 Toliman 2.4GHz Socket AM2+ 95W Triple-Core Black Edition
Power Supply: CORSAIR CMPSU-400CX 400W

Noyabronok · Mar 20, 2009, 04:47 PM

well, I removed all physical inputs from the Audigy PCI card, and removed 2GB of ram, so I now have only 2GB left. The static is still there. I'm thinking of reinstalling the OS, maybe that will make a difference?

Noyabronok · Mar 20, 2009, 11:04 PM

Ok, this is very strange. I installed Windows XP on the same computer (parallel on another drive, so I can switch to Vista quickly). I tried the Creative drivers, and got some static. Now I'm trying the kx drivers. I removed a few of the unnecessary plugins like reverb and chorus from default DSP and that cleaned up the static on an empty line. The kx-Speaker test worked like a charm, with all 5.1 channels coming in clean with no static (kx-speaker test didn't work in Vista, so can't compare). As soon as I try to play a wav file (any of the sounds that come with windows) I get lots of static.

So I kept playing with the DSP in Windows XP, and finally got rid of all the static by creating the flow that I'm attaching below. So, who can make anything out of this?

Noyabronok · Mar 21, 2009, 05:52 AM

Ok, more strange results.

I clean installed Vista onto yet another hard drive on the same machine. I did not load up all my other apps like antivirus. Just Vista 32bit Service Pack 1. I installed kx drivers right away after SP1 update (before I used to try out creative drivers first). I configured the DSP for a 6 channel mixdown to stereo (FX4-9) by using the cnv51to20 plugin. I tested with the Vista speaker test on the Master Mixer in Vista's Sound panel.

* 8 sounds were played (as always).
* The first 6 sounds were almost perfectly clean
* Last 2 sounds had static

Next, I used the Mixy plugin to downmix and monitor level at the same time (easier than using a surrounder and Peak plugins). I wired FX0/1, FX2/3, FX4/5, FX6/7, FX8/9 going into Mixy and coming out to analog stereo. Now, FX4-9 played in turn, but I swear that 90% of the time that I heard static I would also notice jumps on FX0/1 !!!! I played FX 0/1 solo and sure enough, i heard some static.

So, the big question is: why is static being inserted in FX0/1 ???

Russ · Mar 21, 2009, 12:31 PM

So, if you leave FxBus 0/1 disconnected in the default DSP config, does it get rid of the static completely? (BTW: Is this still with only 2GB RAM?)

<edit>
Hmm, in one of your previous tests, you were not using FxBus 0/1, but still had a lot of static...
</edit>

Do you still have XP installed? If so, can you confirm the same results in XP?

It is sounding more like a hardware issue at this point. i.e. Maybe a problem with the card itself, or maybe it is just picking up noise from other components. I would suggest testing in another system if possible, beyond that, move the card to another PCI slot if possible (preferably one as far away from the video card and any cooling fans as possible).

Noyabronok · Mar 23, 2009, 02:04 PM

Ok. So I think one of the major problems of the kx driver under Vista was that I couldn't choose the speaker setup to report to windows. The kx Master Mixer device has 8 channels selected and there was no way to change that. fx 0/1 is always 2 speaker, etc.. Under Windows XP this option is enabled for me to change, and I think it's incredibly useful. Also, kx drivers should have the kx speaker test on Vista fixed as well.

Also, there seems to be a synchronization delay when using the kx-Driver between Video and Audio, which seems to be due to the buffer. I don't have the same delay when using the on-motherboard sound card.

I think I'm going to try using it with XP for a while, see how far I can take it. XP seems to be the most configurable/supported OS when compared to Vista.

Maddogg6 · Mar 23, 2009, 04:16 PM

Just a thought...

Perhaps changing Wave 0/1 Routing in kX Router, see if that has any affect

Try swapping Wave 0/1 with Wave 2/3 (If set to FXBus 0/1 - set to FXBus 2/3 and vise versa)

My thinking:
If it is a hardware problem, maybe it has to do with FXBus 0/1...??

Just a thought.

Noyabronok · Mar 23, 2009, 05:07 PM

Thanks for your suggestion. I'm actually getting clean results on wave 0/1 under windows XP ( I reinstalled XP but did not install creative driver (only kx), then I removed reverb, chorus, fxmix2 and p16v from default dsp), so i'm gonna monitor it over a few days to see how it goes.

My only major complaint left (at the moment) is syncing the audio with video. I reduced the kx buffer to 4ms (it's 8 by default), and that helped a little, but I can't reduce it any further without messing up the sound. Again, my onboard sound card has no delay (it's in sync with video), so it's something specific to my kx-audigy setup. Does anyone have any suggestion for fixing that?

TravelRec. · Mar 23, 2009, 06:44 PM

What video player / app you are using? I can not see any problems with my SB0350 A2ZS with different video applications, Audigy1 and older cards are working too.

Noyabronok · Mar 23, 2009, 06:54 PM

I'm using VLC. I also use Media player 11 with k-lite standard codec pack.

Russ · Mar 23, 2009, 08:14 PM

VLC has an "Audio desynchronization compensation" setting that you can adjust.

As far as WMP 11 goes, be careful with codec packs, it can be hard to tell when some of these codecs are being used, and often they are used when they not needed and can cause problems. In such cases you would need to try and figure out which codec is being used, and see if it has any audio/video sync settings that can be adjusted.

I don't have the same delay when using the on-motherboard sound card. I think I'm going to try using it with XP for a while, see how far I can take it. XP seems to be the most configurable/supported OS when compared to Vista.

Perhaps changing Wave 0/1 Routing in kX Router, see if that has any affect Try swapping Wave 0/1 with Wave 2/3 (If set to FXBus 0/1 - set to FXBus 2/3 and vise versa) My thinking: If it is a hardware problem, maybe it has to do with FXBus 0/1...?? Just a thought.

I'm actually getting clean results on wave 0/1 under windows XP ( I reinstalled XP but did not install creative driver (only kx), then I removed reverb, chorus, fxmix2 and p16v from default dsp), so i'm gonna monitor it over a few days to see how it goes. My only major complaint left (at the moment) is syncing the audio with video. I reduced the kx buffer to 4ms (it's 8 by default), and that helped a little, but I can't reduce it any further without messing up the sound. Again, my onboard sound card has no delay (it's in sync with video), so it's something specific to my kx-audigy setup. Does anyone have any suggestion for fixing that?

I can not see any problems with my SB0350 A2ZS with different video applications, Audigy1 and older cards are working too. __________________ Always take a look behind.

As far as WMP 11 goes, be careful with codec packs, it can be hard to tell when some of these codecs are being used, and often they are used when they not needed and can cause problems. In such cases you would need to try and figure out which codec is being used, and see if it has any audio/video sync settings that can be adjusted.
