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 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

[...]

apparently the devices are wired differently on the T410s (which works here) and the T400s.

Sure. As far as I understand Lenovo is not putting any kind of effort into Linux support. It's hard to test without hardware.

Have you tried playing with the mixers?

Sure, I tried everything I could think of. In the process I found out that I have to power off my machine. Otherwise the mic was not working sometimes after just rebooting from a non working revision into a usually working one.

There might be additional ones present after the patch.

Indeed there are. Not to clutter up the mail I put this to the end of this message.

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?

I don't have a docking station for my T400s. Sorry, cannot test that.

The headphone jack also has a mic in connector (TRRS connector). There the mic works fine. That has nothing to do with the docking station though.
