Hi everyone,

I installed rc6 today on my laptop and discovered sound
no longer works. I can hear a few clicks from the speakers as it boots, but nothing else.

After a while I got the internal speaker in the laptop working by randomly clicking between all the permutations of (mute, speaker, headphone, main, speaker, beep, alsa, pulseaudio) in my mixer app. But, I couldn't get any noise out of the headphone jack.

I took a wild guess based on the changesets to snd-hda-intel and narrowed it down to the change below. With this reverted, I don't have an alsa headphone output anymore (just master, pcm) and everything is working again.

My laptop is an x201, not a T510...

ALSA: HDA: Use model=auto for Thinkpad T510

The user reports that model=auto works fine for him. Using model=auto bring in new features such as jack detection notification to userspace.

FYI, the same effect could be achieved by passing model=thinkpad option to snd-hda-intel module without recompiling, too.

Could you give alsa-info.sh outputs (run with --no-upload option) on both working and non-working kernels?

thanks,

Takashi
