Audio doesn't route to headphones on Macbook 5,2 for Ubuntu Maverick due to existing mb5 quirk

[Roberto Cássio Jr.]

Clean install of Maverick beta. Tryed playing with alsamixer , mutting/unmutting various things, and it didn't work. I only get audio from the Macbook's internal speakers.

Confirm. I also use Maverick RC amd64 and no sound in headphones. Also doesn't work microphone input.

Igor, please file a separate bug, with the command "ubuntu-bug alsa-base", as your hardware is different to the original reporter.

[Roberto Cássio Jr. (rcsdnj)]

This problems persists exactly in the same way in Natty Narwhal.

[Roberto Cássio Jr. (rcsdnj)]

On Natty, I'm able to get sound working fine by adding "options snd-hda-intel model=mb31" to /etc/modprobe.d/alsa-base.conf file.

So, to fix this bug, wouldn't be enough to update the auto-detection list in order to Macbook 5,2 use the model mb31?

[Daniel T Chen (crimsun)]

What about recording?

[Roberto Cássio Jr. (rcsdnj)]

Recording is also working fine with the same workaround. I think I just
had to unmute it, not sure.

There is an existing quirk that uses the Macbook 5,2 model (model=mb5), so "fixing" the autodetection (codec SSID, not PCI SSID) would likely regress other models.

[Roberto Cássio Jr. (rcsdnj)]

I'm not sure I understood the problem. I thought that just loading mb3
mode for Macbook 5,2 would fix the problem, without affecting other
machines - since this detection would be applied only for this specific
model.

Anyway, is there anything else useful I can do to help with fixing this
bug?

If you can clarrify a couple of things for me, I can come up with a new quirk especially for MacBook 5,2 machines. I'll break it down into a series of questions about using the mb31 quirk, and using the current default for your machine, the mb5 quirk.

With the mb31 quirk:
Does headphone jack sense, i.e connect headphones, turn off internal speakers, disconnect headphones, turn on internal speakers work?
Does line in, and the internal microphone work?
Does digital/optical in work? (Don't worry if you can't test this.)

With the default/mb5 quirk:
Does headphone jack sense, i.e connect headphones, turn off internal speakers, disconnect headphones, turn on internal speakers work?
Does line in, and the internal microphone work?
Does digital/optical in work? (Don't worry if you can't test this.)

If you are able to answer as many fo the above as possible, I will be able to take a look at the code responsible for setting up the chip in your machine, and as I said above, possibly come up with a new quirk for that model of machine. Once done, I can make a test package for you to try.

Thanks

Luke
