Hi,

I have a problem since commit id 7b2bfdb (about 2.6.35-rc2) up to the
latest HEAD on my Lenovo T400s laptop. Just found out while testing Ubuntu
10.10.
Problem is: Headphones dont work any more, internal Microphone doesnt
work any more. However, if I load snd-hda-intel with the option
model=ideapad the mic and the headphones work perfectly well again. For now
that is an acceptable work around. However, before the aforementioned
commit I didnt have to provide any module parameters.
Before rev 7b2bfdb I had:
└[a8@t4]-~→find /proc/asound/card* -type f | grep codec | xargs grep
"^Codec|^Vendor Id|^Subsystem Id|^Revision Id"
Codec: Conexant ID 5069
Vendor Id: 0x14f15069
Subsystem Id: 0x17aa2132
Revision Id: 0x100300
Starting with rev 7b2bfdb I get:
└[a8@t4]-~→find /proc/asound/card* -type f | grep codec | xargs grep
"^Codec|^Vendor Id|^Subsystem Id|^Revision Id"
Codec: Conexant CX20585
Vendor Id: 0x14f15069
Subsystem Id: 0x17aa2132
Revision Id: 0x100300
BTW, all the bisecting is done out of the linus.git tree.
Thank you for looking into that. Im happy to provide more information or test
patches.
Thanks,
Frank

Hello Frank,
apparently the devices are wired differently on the T410s (which works
here) and the T400s.
Have you tried playing with the mixers? There might be additional ones
present after the patch.
Also when you say things work perfectly when specifying "model=ideapad",
does that include automatic switching between internal and external
microphones? Have you attached your T410 to a docking station?
Also, itd be helpful if alsa-info.sh output is given.
Jens, Frank, could you guys run it with --no-upload option and attach
the output for comparison?
thanks,
Takashi
