hello.

i hear random time sound clicks. this happens in all applications. i mean. asio, directsound and everywhere. my hardware acceleration is set to maximum. speaker setup is 5.1 surround sound system.

please help me to troubleshoot this issue. these clicks are very annoying.

also my asio seems to not working correctly. whatever i latency i set it has some problems.

i have recently upgraded my pc.
20ms latency:
before it was working with 533Mhz Celeron,
now its not working with my new 1.7Ghz @ 2.0Ghz Celeron. PCI/AGP=33/66Mhz
i have installed my windows 2000 adv. server with ACPI but my sound card is not sharing IRQ (22). i have ct4830.

10x in advance.

trance1meister

the readme file, recommends disabling ACPI before installation of the drivers.

device manager > computer > ACPI PC properties > update driver > standard PC.

this way isn't recommended by microsoft, but it worked for me.

the best thing to do if possible would be to to disable PNP in the bios, and then reinstall windows. this should install the system with ACPI disabled.

i don't think that i have acpi problem.

i have checked this page http://kxproject.spb.ru/acpi.php?language=en
there is written:

"ACPI issues typically cause problems only when your soundcard shares an IRQ with other PCI/AGP cards"

but my soundcard don't share its irq.
my mainboard have apic that as i know support more irqs.
my case its irq 22. my card use it alone.

can this really be an acpi issue?

imperia

when i use asio and setup my latency 42.66ms there are no clicks!, when i setup my latency to 21.33ms the clicks appear again. so is this acpi issue for sure, because i don't want to lose my acpi. and if this is acpi issue - can i change the latency for the MME/DS driver? so i can have ACPI + kxdrivers?

update 2:
it seems that the clicks (in directsound-watch movies, warcraft) are in random interval (example 1 min. nothing and then few clicks then again some pause......)

trance1meister

hmmm.....

trance1meister

oops!
what I was going to say was....

if I had this problem, I would try the following:

1.disable ACPI (though you say you dont want to do this if at all possible)

2. change the IRQ of your sound card (i can't remember if win2k can change the IRQ in device manager or not, maybe you have to change them in the bios, *or try the sound card in a different pci slot*)

3. change PCI latency value in the bios. try setting it lower than what it was. if that doesn't work, try setting it higher than what it was. if things still don't work, set it back to what it used to be.

imperia

all the noises are random noises/hum not frequent skipping/constant time interval.

can this be some kind of ground looping?

imperia

to authors:

can i have your attention for my problem.
how can i diagnose if it is acpi problem for sure.
i dont want to fuck up my freshly installed windows just to test if it acpi problem.

[sorry for the delayed answer -- NewYear / Christmas holidays]

well, your issue might not be ACPI-related.
what chipset are you using? is it VIA-based? -- read our article on the site, if yes

does the click happen when you playback MIDI files?

is it possible to record the click? [that is, reset the settings and try recording 'what you hear' (the default option) until you hear the click. is it reproduced in the recording?]

do you have any CPUCool-like software running?
try unloading ANY software you might have running and try reproducing the issue

make sure you have reset the settings (via kX Mixer) before any experiments

...there might be some more reasons for the clicks...

nice to see you again. about the new year/x-mas delay. i wish you a lot of bugfree software in this new year , Health & Happiness.

Intel 845E - GIGABYTE GA-8IE533 mainboard

i just checked that and i think the answer is NO. i will check again, but i think the clicks are gone when i play MIDI.

i will check that, but i think that the clicks are not recorded. i will double check that. the clicks are at random time intervals, not constant one.

MBM5 - motherboard monitoring software. maybe i should uninstall it completely (not only unload) because it may have some driver installed(almost sure for this)? advice me.

just reinstalled the driver with --clean option. hope this is enough. now i just have set buffer to 16384 just to check. then i reinitialised the dsp and the clicks are still here.

will be nice to hear them. but first let me check these things. and tell me please what you think.

regards,
imperia.

i think the card records everything right but when i have to play it back it have new clicks ontop(just because i have clicks).
so: the clicks are ontop

Test DirectSound - 8bit Mono 22khz software buffer - here i hear lots of clicks. similar to listening to vinyl.
other test have quieter clicks.

try to increase your PCI latency (via BIOS)
it seems to be a hardware problem
do NOT tweak the buffer sizes via kX Mixer (RESET the settings)
also, try uninstalling MBM before additional tests

imperia

i do not have latency settings in bios. i have only some "Top Performace" with enable/disable options.

can MBM cause the problem when the clicks are at random interval?

Eugene Gavrilov

might be

imperia

it seems that the problem was caused by mbm. i uninstalled it and now i have the lowest latency of 2.66ms..
10x for the help
