Sound suddenly broken

Scroll down for a new issue!! (not mine)

as for mine...

usr err, please replace usr

(a recompile of alsa and some fiddling with alsamixer fixed all... not sure what it is)

Re: Sound suddenly broken

I have a similar problem with my Intel HDA audio card:

 00:1b.0 Class 0403: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
        Subsystem: Hewlett-Packard Company Unknown device 30a5
        Flags: bus master, fast devsel, latency 0, IRQ 22
        Memory at d2400000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access>

I have tried almost everything: with and without aliases in modprobe.conf, with and without:

options snd-hda-intel <model>

from this list of options.

Tried also:

options snd-hda-intel position_fix=1

But all this was useless.

At the end I have managed to make it work with an unbelievable solution: I blacklisted all the snd modules and removed alsa from the DEAMONS array in /etc/rc.conf.

Then I made a little "script" called /etc/start_snd:

modprobe snd-hda-intel
modprobe snd-pcm
modprobe snd-pcm-oss
alsactl restore

chmoded +x it and added it to rc.local. I set up the alsaconfig and did an alsactl store. After reboot everything is working fine. (but I didn't test the mic).

I really don't understand why it does work... maybe some issue if the modprobe is at the beginning of the boot sequence with the udev....

Hope this can help.
