[SOLVED] No sound from sound card

cesura · 2011-04-20 03:45:55

I'm going to be quite brief about this, because the details have been repeated so often in many other threads. Just recently (as in a few hours ago), my laptop (ThinkPad T31) is no longer producing any sounds, despite the card being recognized. Trying to troubleshoot this issue, I tried a variety of different solutions I had found during my research:

Some info:

lspci | grep Audio wrote:

lsmod | grep snd wrote:

soundcore 4545 1 snd
snd_page_alloc 5745 3 snd_intel8x0m,snd_intel8x0,snd_pcm

amixer output: here

I have tried blacklisting snd_intel8x0m in /etc/rc.conf, as well as try using OSS, both to no avail.

I have also tried placing:

options snd-intel8x0 ac97_quirk=1

in /etc/modprobe.d/modprobe.conf

There were actually many more things that I have tried while sifting through all of the past forum posts relating to this issue, but I won't go into to much detail. Could anyone explain what I need to do, or at least point me in the right direction? I am absolutely baffled, especially considering I had not updated anything before the problem occurred.

EDIT: I also tried a different kernel, in this case kernel26-lts, which, again, produced no results.

I can't be certain but your PCM channels are completely muted and AFAIK should not be. Try unmuting PCM ?

Nice catch! Unfortunately, the PCM channels have never worked for me (I use 'Master'), so I always keep them muted. I tried unmuting them without any luck.

Uh, I suppose it is fixed now. It turns out that...err...my laptop speakers were muted on the hardware itself. My eleven-year-old sister fixed it.

Thank you interwebz. Message terminated.

Both you and your sister deserve an award
