Public bug reported:
Binary package hint: linux-source-2.6.20
This is a regression from Herd 4. In Herd 5, no sound or microphone
works. In Herd 4, sound worked (built-in speakers and headphones) and
line-in microphone (but not the built-in microphone) worked. In Edgy,
only the sound (built-in speakers and headphones) worked.
Hardware:
ASUS F2JE laptop, Intel HD Audio, some Realtek audio controller (not sure which
one, because see "Details" and attached outputs)
Details:
No sound is present (but present in "Volume control"), and none of the 2
microphones are present even in the "Volume control" application. In the
"Volume control" application, in File->Change Device, I see only "0:
Realtek ALC660 (OSS Mixer)". When unmuted, whenever I try to move the
only slider, labeled "Volume", to some value in the middle, it jumps
back to maximum. No other devices are present, like 2 microphones that
should be (one built-in in webcam, second as pluggable line-in).
"dmesg" shows something about unknown device ALC861 (see output in
attachement). The title of "Volume control" application shows "Realtek
ALC660 (OSS Mixer)" (same as the device in File menu). Note that
/proc/asound/pcm speaks again about ALC861, not ALC660 (tar.bz2 archive
of /proc/asound attached).
Please find in attachements tar.bz2 archive of /proc/asound, then
outputs of "dmesg", "lspci", "lspci -n", "lspci -v" and "lsmod".
If you need any info or further testing, I will be glad to provide.
Best regards,
Boris Dušek
