Public bug reported:
I have attached the output of "lspci -vv". My microphone does not work
right from hardy heron to intrepid, even though I am now using the
latest kernel (updated on Nov 3 2008) on Intrepid Ibex:
[EMAIL PROTECTED]:~/misc/soundtest$ uname -r
2.6.27-7-generic
gnome-sound-recorder just freezes after I click "Stop Recording", and
the record does not work giving the following output:
[EMAIL PROTECTED]:~/misc/soundtest$ arecord -vv -fdat foo.wav
Recording WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
ALSA <-> PulseAudio PCM I/O Plugin
Its setup is:

Here is the output of amixer (before I performed the previous test):
[EMAIL PROTECTED]:~/misc/soundtest$ amixer
Simple mixer control 'Master',0
Capabilities: pvolume pswitch pswitch-joined
Playback channels: Front Left - Front Right
Limits: Playback 0 - 65536
Mono:

Front Right: Playback 62914 [96%] [on]
Simple mixer control 'Capture',0
Capabilities: cvolume cswitch cswitch-joined
Capture channels: Front Left - Front Right
Limits: Capture 0 - 65536
Front Left: Capture 65536 [100%] [on]
Front Right: Capture 65536 [100%] [on]
And version of alsa is:
[EMAIL PROTECTED]:~/misc/soundtest$ alsactl --version
alsactl version 1.0.17
So I guess this means that this audio card is not supported by Alsa? The thing
is that the mic has worked on Suse Linux enterprise, which I uninstalled!
There are lots of bug reports mentioning mic not working in many
laptops; I'd like to help get it working, so please let me know if there
is any additional information I can provide.
