hi everybody,
I have 2 sound cards: integrated Intel and Soundblaster Live
Since 2 weeks, I have a very strange behaviour of the Soundblaster Live

- after each reboot, the sound is perfectly normal.
- after 1 or 2 hours, it becomes crazy: when I play a short sound (1 second),
with aplay, it is echoed about 20 times, and I get :

Playing WAVE '/sound/wav/woow.wav' : Unsigned 8 bit, Rate 11025 Hz, Mono
aplay: pcm_write:1266: write error: Input/output error

with mplayer, it is echoed 8 times
with play(sox), it is echoed indefinitely, and I must issue a "kill -9"
idem with totem, gxine, kaffeine
with vlc (ALSA audio output), the sound is normal!

With a longer sound, the 10 first seconds are normal, and then it
becomes garbled (with all players)

- if I use the Intel card, the sound is OK in all cases.

I'm ready to install Intrepid, but before, I would like to elucidate
this mystery.

NB: I saw some bug reports about the pcm_write error message, but what
puzzles me is that I only get it a variable time after reboot!

cheers,

I had a similar problem in Hardy. Turning down the AC97 slider in the
mixer fixed the problem. I have no idea why it happened all of a
sudden.

FWIW All of the instructions for building PCs that I have or have seen
mention going into the BIOS and disabling the on-board audio if you wish
to use a sound card. My desktop has a Soundblaster Live sound card
running under Intrepid with no problem.

YMMV

hi Michael,
I tried to turn down all possible sliders in alsamixer, but
this changed nothing.
You said you had a similar problem in Hardy. Do you have Intrepid now?

Doing some googling, I found both instructions (disable or not disable in BIOS)
- I don't see why one card should be disabled to use the other.
For example, you can have 2 ethernet cards. Why not 2 sound cards?
- actually, both cards worked perfectly during 6 months, and as I said,
both work perfectly 1 or 2 hours after reboot.
- anyway, I tried to disable the integrated card, but after that my machine
don't boot: stays indefinitely on "checking NVRAM" (apparently a BIOS BUG...)

cheers,

Actually all of those instructions assume that one is building a Windows
machine. That surely has something to do with it. I try to only build
Ubuntu machines. (The desktop I referenced is a dual booter cuz my wife
uses it.)

YMMV

Due to another problem which has yet to resolved I'm still using
Hardy. I have Kubuntu 8.04 installed.
