Hi,
Please always CC me since I'm not subscribed to the mailing lists.
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 don't work any more, internal Microphone doesn't 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 didn't 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. I'm happy to provide more information or test patches.
Thanks,

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, it'd 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,
