1. What are your computer/motherboard brand and model?
2. What is your os version (run "uname -r")?
2. What does "pciconf -lv" says about your audio device? I once fixed
the driver because on my PC the output was going to the speaker, not
to "line out". You may have a similar problem.
1. Boot with either the GENERIC kernel or a custom kernel without any
2. Set the sound debugging messages knob:
3. Load the driver:
4. Get the driver debugging messages:
sed -n 's/.* pcm0: //p' /var/log/messages > hda_log.txt
Send a message to this list with the contents of hda_log.txt.
If you think things can't get worse it's probably only
because you lack sufficient imagination.
