[Alsa] Sudden troubles : no sound

Message

Hello all,
until yesterday, all was fine, and running perfectly.
Since yesterday, and a problem with grub (seems no relation), I have no sound anymore !
Videos, mplayer, mpg123, xmms, everything hangs (the player alone, not the whole system), with a common warning from everyone :

Code: Select all

ALSA lib timer_hw.c:269:(snd_timer_hw_open) extended read is not supported (SNDRV_TIMER_IOCTL_TREAD)

I think I upgraded alsa very recently, and this may be the cause

Here is my version :

Code: Select all

cat /proc/asound/version 
Advanced Linux Sound Architecture Driver Version 1.0.9rc2  (Thu Mar 24 10:33:39 2005 UTC).

I have all files, /dev/dsp, etc etc... I changed nothing, just an upgrade I think.

Here are the versions of libs and all. Has anyone got a clue ?

Code: Select all

[I--] [  ] media-libs/alsa-lib-1.0.10_rc3 (0)
[I--] [  ] media-plugins/xmms-alsa-1.2.10-r2 (0)
[I--] [  ] media-sound/alsa-utils-1.0.10_rc3 (0.9)
[I--] [  ] media-sound/alsa-headers-1.0.10_rc3 (0)

Thanks a lot

I'm having the same problem. It was working yesterday on my laptop, running the intel ac97 drivers. I had to do a re-install and now it's not working. Could be an update issue? Or maybe I was just messing around with too many use flags. I have -esd set in make.conf.

Code: Select all

 cat /proc/asound/version 
Advanced Linux Sound Architecture Driver Version 1.0.9rc2  (Thu Mar 24 10:33:39 2005 UTC).

Did you manage to fix it?

echo /dev/urandom >> /dev/dsp gives me static
so i don't think it's a hardware issue
it might be a problem with alsa-lib?

Hello Peddie,
What I did yesterday was a full reinstall of alsa-lib, alsa-utils, and alsa-headers, after unmerging them, deleting portage source files, and distfiles...but I still got the same problem.
I was advised to rebuild a clean kernel ...

About an update issue, I updated alsa last time on Thursday (17th of Nov. 2005) to its actual status. But I'm pretty sure I used mplayer to see videos, and play mp3 since then...So it may be something I updated after alsa ! I'll check as soon as I get back from work !
Thanks

I did emerge esound and using esdplay to play the sounds works now, although I still get the error in the console. aplay seems to work too. I also did emerge portage, which is probably unrelated but you never know.

Hello,
I already had esound, and esdplay installed. But although I get the error too with esdplay, I have no output

Have you tried upgrading to the latest kernel? Try that, and then

emerge alsa-lib alsa-headers
