Description Claudio Saavedra 2012-04-08 12:34:04 UTC
I have a thinkpad x201 and a x200 ultrabase station and since the upgrade to 3.3.0 there is no sound coming off the output in the dockstation. Booting with 3.2.10-3 brings sound back, so this seems to be a regression in the kernel.

Comment 1 Claudio Saavedra 2012-04-13 06:29:58 UTC
This is still an issue in 3.3.1-3.

Thank you for testing.  I've emailed upstream about the issue and hopefully
we'll have an official fix of sorts shortly.

Comment 4 Josh Boyer 2012-04-13 13:28:35 UTC
Claudio, upstream has a different thing for you to test if you would be so kind.

You'll need to boot back into the non-scratch-build kernel to do this, so 3.3.1-3 should be fine.

Create a file named /lib/firmware/alsa-tp-dock with the following contents:

0x14f15069 0x17aa21a4 0

0x1a 0x21a11000
0x1c 0x23014250

Then in /etc/modprobe.d/dist-alsa.conf, add the following:

 options snd-hda-intel patch="alsa-tp-dock"

then reboot (or rmmod/modprobe the drivers).

After the driver is loaded with that set, new mixer elements will appear.  You will need to look at the volume and mute settings for those manually.

Instead, there is a new scratch build to test if you would please.  You will find it here when it finishes building:

I tried this one without doing the modifications you asked for earlier, and sound is gone. Sorry for the late reply.

Comment 7 Claudio Saavedra 2012-04-20 10:05:57 UTC
3.3.2-1, which seems to be available in the stable repo, is also broken. I tried the changes comment 4 with this and the scratch build in commend 5 without success either.

Comment 8 Josh Boyer 2012-04-20 12:49:57 UTC
With the scratch build, do new mixer devices show up?  You might have to manually adjust the mute and volume settings the first time.

Please attach alsa-info

Seems to work with stock 3.3.4-3.fc16.x86_64 .

Thanks for letting us know Claudio.
