Once I touched something on the mixer AC97 page I think the button that is supposed to route to AC97 or I2s the controls no longer worked and not matter what I did that remained so.

This is not unusual for the SB0400 (Audigy 2 Value): on one occasion (that has never been repeated) the speaker test worked all speakers of 5.1 made noises but only once and I cannot repeat it no matter what I do.

Your new control to either come via the Philips ACD or by the AC97 seems to have the same behavior. If I could repeat it without to much hassle I would but with several tries I could not.

THe original FX SRC worked I could reliably get line-in and connect it to K2 to get to wave out to Windows applications. It was quite repeatable. But this present situation is fleeting I have no hard information it is not repeatable.

The most I can say is that like the original phantom speaker test that worked just once, it was just after I first invoked the the DSP objects concerned for the first tiime that it worked and I coiuld flip back and forth from AC97 to the Philips ADC. I could see input signal in peak and through to a Windows application, but not after I changed things on the Mixer AC97 panel. RE boot te al nothing nada!

Suggests that when the issues wiith this Creative chip are sorted out your code will work.

Hmmm,..yes that must be a typical A2 value issue.
Can you get a constant 'Philips ADC result' when using the kxctrl command lines like;
kxctrl -sac97 2 0 etc..?

Ok its working now and without the command line.

Of course no output goes to the speakers or headphones but that is normal for an Audigy 2 Value for now.

The Enable UDA switch on the ProfX AC97 tweak window and the AC97/I2S bullseye on the kX Mixer AC97 Window (for the beta 3538) fall over each other they are both toggling the same thing.

AS well the Input volume slider on the kXmixer AC97 page (for aux in my case) is the source slider whereas the AUX Mixer slider on the ProfX AC97 tweak window.

That is if I set the ProfX AUX Mixer to 0dB and then trim the gain on the kXMixer AC97 page I get lower noise from the Philips UDA than from the AC97 ACD.

(All other inputs on the kX mixer page are muted)

The war between the toggles has several dimensions: Both are toggles and both have a visible element. When either are moused they visually go to the other state; but the actual state of the real (hidden) switch may not be in the state that either toggle expected so the result can be from null to confusing and the final visual state of either toggle does not necessarily represent the real outcome.

So its just a smidgen confusing.

That the input channel volume slider is still in the kX Mixer Ac97 page when it is the Philips UDA I2S that is involved is a little bit sad. Kind of compounds the ambiguity.


There may be some other effect that I have not yet tripped over again that will wipe it all out, but it is working for now and that is what I see.

Yes, Sb0400 has different hardware and is (not yet) fully supported by the driver.
Latest ALSA drivers do. (Creative donated a card to them..nice)
Unfortunatly I don't have a sb0400 at hand to test the alsa code.

I recall reading somewhere you are a programmer yourself?
If so, you could use kX driver interface to write to/configure/test the card yourself.

/LeMury

John Lodge

Well it is not entirely true to say the SB0400 does not work.
The "Windows start" plays which is to say that the hardware driver works but as soon as kmixer.exe -startup runs there is silence. In the most simple minded way of looking at it: the reset of the DSP by kmixer is negating the default that the hardware driver initialises.

Indeed in the past I was a programmer but that was a very long time ago.

You might want to think about the way the two toggles are falling over each other. Of course you may be dealing with write only registers; if not then both your code and the kmixer code need to test the register before changing it so that odd funny does not occur. Or is this another manifestation of the partly supported hardware.

My russian is really poor now (it was better 40 years ago) but clearly there is a lot of activity in the russian language forum in regard to the SB0400.

I've just installed my Audigy2 Value and tried to configure DSP with ProFX plugins. I put k2lt plugin and found that analog outputs are swaped with digital. I'm using "SPDIF Out/Digital Front" for analog LineOut 1 and "Digital Rear" for LineOut 2.

Well dead utter silence is what I get.

I have taken a Wave Generator 3 peaked it to make sure it is outputting and then connected the sine wave to all the k2lt inputs except the last two which are WinMM Recording and shuffled the outputs around, I find nothing that gives me any sound. Did you have to do anything with the routing to get it to work??

Also was it an SB0400 not sure if there is more than one value card

popej

Yes, my card is SB0400.

Did you set SPDIF to 96000 in kx mixer master view? I found this sugestion in other threads and followed it blindly, but it really makes difference. With value other then 96000 card is silent.

Popej,

Got it!!! sound at all 5.1 speakers. Using Src for FXBus 0/1 to run WMP through MX6 to K2lt. Yes and only when mixer SPDIF is set to 96000.

Thank you for your help

...John

popej

I'm glad to hear it :-)
Did you succeed in 24-bit playbac/recording? I cannot get any sound from wave HQ.

To be on topic, I'd like to say that both AC97 and SRC work on my Audigy2 Value. Now I finnaly understand how ac97 codec is connected.

popej and john,

Can you both confirm the same conclusions/questions after switching to 96k;

- analog outputs are swapped with digital
(btw: Does this also happen with Epilog as well?)

- does the UDA switch work on [AC97] plugin?

- could you both post your card's PCI Device/Vendor ID?
(just hit kX 'about' menu)


/LeMury

popej

Precisely speaking I located only analog outputs, in k2lt it goes like that:
SPDIF Out / Digital front -> line out 1 (front)
Digital Rear out -> line out 2 (rear)
Digital Center /LFE out -> line out 3 (center/sub)
Where do other outputs lead I cannot say.

In Epilog:
Analog Front L/R [swapped] out1 -> line out 2 (rear)
Generic SPDIF L/R out2 -> line out 1 (front)
Digital Center/SUB / SPDIF1 out5 -> line out 3 (center/sub)

In both cases front/rear outputs are swapped in kx mixer.

Yes, it works perfectly. Only one small complain: the UDA check box does not mute plugin output. ADC does not works but output noise remain.

when i try to register this, it gives me an error saying, invalid plugin library? im running newest drivers on an audigy 1, any suggestions?

-thanks

John Lodge

The output to speakers is on the digital out, I cannot confirm swapping not sure if there is a way of getting anything on the other side. But I see that it is documented that AC97 is not used for output for Audigy 2 so it sort of makes sense.

THe UDA does indeed work and I do get better S/N

It only works at 96000.

Also Midi works.

The Windows interface is a bit off.
Stepping through the windows mixer/volume controls:
the plays show the usual suspect:
Wave, CD Player, K1 Micin, K2 Lin In, Synth
but the records only show a single recording level
except for HQ where recording is blank and other is "Wave In"

There seems to be more wrong with HQ than others.

From the way Adobe Audition is reacting the Windows driver (not ASIO which Adobe does not support) is doing an handshake error dropback. I am still getting 24bit with Audition but it is not showing up as it would if there way a faultless handshake. (I would get a float indicator not a 24bit record indicator) but recorded info still analyses as float.

I have not tested epilog yet. I will get back to you.

Incidentally is the new MX6 supposed to install in 3538 all I get for it and for vu3 is invalid plugin library.

OK now to answer the outstanding bit about epilog.

I used epiloglt_k2.

Well when I unloaded k2lt sound (midi) continued through the centre channel

went to a clear DSP still continued
went to a reset DSP and get stereo sound.

The only thing that stops the centre channel it is nixing midi synth in the main window slider (other than going away from 96000).

on epiloglt_k2 full midi is when the first 8 the spdif inputs get data.

...John

Lex Nahumury

I have never released any 3538 MX6 or Vu3.
Those are 3537 versions.

/LeMury

PS:
It's not uncommon that playback will continue to sound even if dsp is cleared or reset.
Only after start/stop, playback buffers will be released.
Keep that in mind while testing.

John Lodge

Thanks, I must have known that but forgot.

As well while running through the SRC input I find that on FXBus12/13 that the R channel also shows Midi. Looking at the Router and going to Channel 13 and then zeroing slider in the 3rd position stops it. But it does not matter what is referred to under the slider (ie clicking to open). That is I can set in to any of the 64 channels and the effect is the same there is signal but only in the 3rd position and for channel 13 under the synth1. (Well it is synth1 I am using right now).
