I have installed FC12 on a Thinkpad R61i, Intel Dual Core. The problem is that audio devices are not always working.

I have modules snd_hda_intel and snd_pcm:

..................
snd_hda_codec_analog 54684 1
snd_hda_intel 25080 4
snd_hda_codec 60584 2 snd_hda_codec_analog,snd_hda_intel
snd_hwdep 6900 1 snd_hda_codec
snd_seq 46960 0
snd_seq_device 6232 1 snd_seq
arc4 1616 2
ecb 2492 2
snd_pcm 64772 2 snd_hda_intel,snd_hda_codec
snd_timer 17992 2 snd_seq,snd_pcm
snd 50908 16 snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_seq,snd_seq_device,snd_pcm,snd_timer
.......................

When I run amixer also seems ok:

# amixer

I also tried to kill and restart pulseaudio:

Apparently the moudle is not loaded, but the daemon is anyhow started. What should I do?

Many thanks in advance.

try the above link.. this might get your headphone sound back..

Hum. Compare your config file with this one on my systems.That's a default set-up. You might also want to see what "audio" processes are running:Note that, on my system, both the audio driver ([hd-audio]) and the local process (/usr/bin/pluseaudio) are sleeping. That's because I don't, normally, let my laptop generate any sounds, since I don't like it when other users bother me with their sound systems.
