Bug Description
Machine : Asus EeePC 1002HA
Sound Chipset:
root@xtro:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
Subsystem: ASUSTeK Computer Inc. Device 834a
[...]
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel
Symptom :
- Worked perfectly in Intrepid without any configuration pain
- Doesn't work anymore after upgrade to Jaunty - NO SOUND.
- Almost all mixer controls have disappeared from Alsa mixer, except for "PCM" and "LineOut", but they don't allow producing any sound.
- No more "Master" "Front", etc, controls.
(Addl Information : I also have a Dell XPS M1330 With Intel ICH8. On this one sound works after Jaunty upgrade, however the "PCM" slider control has no effect anymore (moving it is ignored), but PCM sound is there.)
affects: | ubuntu → linux (Ubuntu) |
After exploring a bit the available models choices in kernel source's Alsa source code (a pity it seems undocumented besides the available models listed in the source code), I tried in /etc/modprobe. d/alsa- base.conf:
options snd-hda-intel model=eeepc-p901
Which seemed to be the closest hardware to what I have, but it didn't help. Still no sound and few useless cursors in the mixer...
