Description Alexey Eremenko 2005-08-28 17:10:12 UTC

My sound system gets sometimes corrupted output - i.e.
zero quality. i.e. playing .ogg vorbis in XMMS - I just hear noise.

Possibly it's due to bug: 113311

However, because I'm not sure in the origins, I have opened a new bug.

How can I output/redirect my "buggy" sound to a wave file?

Of course I can use my stereo system as tape recorder, but possibly, there are
other ways exist...

My hardware: AMD Sempron CPU, 1GB RAM, VIA KM400 chipset, VIA 8237 audio.
OS: Suse Linux 10.0 BETA3 with KDE

Comment 1 Takashi Iwai 2005-08-29 09:36:15 UTC

Is the problem resumed when you once stop and start xmms?  Or does it occur
constantly?

To record in a loop-back:
Choose "Mix" as the capture source on alsamixer, turn on "Capture" switch and
raise "Capture Volume".  Then run "arecord -fcd foo.wav" to record the
redirected sound.

And, no, it's irrelevant to 113311.

Comment 2 Alexey Eremenko 2005-08-29 15:07:13 UTC

Well, no, starting and stopping XMMS doesn't have any effect on corruption.

But after full system restart the effect above sometimes takes place.

The problem of "sometimes" means - that I can't predict it, nor write guidelines
of bug reproduction.

I'll keep investigating and collect data when this will happen again.
Currently everything works fine.

Comment 3 Alexey Eremenko 2005-08-29 15:21:33 UTC

btw: thanks you for teaching me how-to capture audio !!!

That works, but somewhat very very quietly. About 10 tiles quiter than original.

Comment 4 Alexey Eremenko 2005-09-01 16:11:06 UTC

can't reproduce that...

Closing.

Comment 5 Alexey Eremenko 2005-09-05 18:06:38 UTC

Hell and Thunder !!!

It happened again... the sound corruption takes place randomly, from time to time...

Comment 6 Alexey Eremenko 2005-09-05 18:09:33 UTC

hmmm... now I have changed the volume in KMix, and that problem disappeared.

Last time I had this problem when:
XMMS volume=100%
Master Volume=70%
Wave Volume=70%

Maximizing the volumes to 100%, and that dissapeared. Mysteriously.

Comment 7 Alexey Eremenko 2005-09-05 18:15:14 UTC

what's interesting - before I have touched volume in KMix, I did

linux:/home/alexey # rcalsasound restart
Shutting down sound driver                                           done
Starting sound driver:  via82xx                                      done
linux:/home/alexey # 

however, no effect achieved. This command did not fix the problem.

Comment 8 Michael Gross 2005-09-06 10:21:37 UTC

This might also be a defective sound card. I got such a card once. Worked fine
for some time and totally screwed up every now and again. Please get sure your
card isn't defective (maby by trying under another OS). Reducing the severity to
`normal' at the meantime.

Comment 9 Takashi Iwai 2005-09-06 10:24:43 UTC

Yep, the symptom sounds like a hardproblem, or a very deep probem related with
other stuff like cpufreq.

Anyway, try once to add "dxs_support=5" module option for snd-via82xx in
/etc/modprobe.d/sound.  But don't expect too much.  According to comment #7,
this won't be cured by restarting the driver, so the problem is likely outside
the sound driver.

Also, please show the output of "lspci -nv" for further checking.

No reaction on this bug for more than 17 months. Closing as CANTFIX.
