Public bug reported:
Sound from speakers has stopped working on Asus EeePC 1015PN , but sound
from headphones still works. Sound worked fine during initial install,
but has stopped working. It may be related to a BIOS update (possible
BIOS mis-reporting pins or jacks or driver not getting information
correctly?) Unfortunately, BIOS cannot be downgraded to confirm -- all
ASUS BIOS software refuses to flash to older BIOS (no force option).
Currently using 11.04 with all updates installed, but problem appears to exist
in 10.10 as well
alsa-base version is 1.0.24+dfsg-0ubuntu1
These are the troubleshooting steps I've tried with no effect:
- check levels in alsamixer (all at 100% except mic boost, shows in
alsa-info as 100% as well)
- booting from LiveUSB, problem is there, too (did not used to be)
- booting from 10.10 LiveUSB, problem is there, too (did not used to be)
- installed linux-alsa-driver-modules-2.6.38-8-generic
- sudo modprobe snd-hda-intel
- adding "options snd-hda-intel model=asus" to alsa-base.conf
Internal microphone works
Speakers work in Windows
lspci shows both audio cards correctly (the Intel one is what stopped working):
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio
Controller (rev 02)
04:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev
a1)
