| |
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.
