Baytrail init file for alsa-utils

Baytrail init file for alsa-utils

[Bastien Nocera]

Hey,

I've done some work on the community generated "alsa state" file for
Baytrail tablets, and shrunk it massively:
https://github.com/AdamWill/baytrail-m/blob/master/alsa/t100_B.state

Are there any tools, or hints as to how I might convert that to an
"init" file that alsactl could run to set the default state of the
mixer?

Or have any Intel folks already done that work?

I'll have a few more sound-related questions for that tablet, for which
I could do with a few hints as to where to direct the questions/bug
reports:
- no jack sensing support (driver problem?)
- left/right headphones output is inverted (another driver bug?)
- HDMI audio is not detected (Intel video driver bug?)

Cheers

"alsactl store" should write it to the correct system directory.

Jarkko has been working on Baytrail so best for him to answer.

alsactl store doesn't use a format similar to the files installed
in /usr/lib/alsa/init though, which is what I'm looking for.

Ah, sorry. No I have used just the alsamixer and alsactl.

Could you answer this couple of questions though?

* Is this trimmed down ALSA init state correct, can we trim more?
https://github.com/AdamWill/baytrail-m/blob/master/alsa/t100_B.state
If you have access to more hardware than me, I would appreciate if you
could test it so I can be sure I didn't break anything, before writing
the init file for alsactl.

* Jack sensing doesn't seem to work, though I can switch manually to the
headphones and Headphones Left and Right are inverted.

Are those hardware issues (that could be quirked in the driver), driver
issues or configuration issues?

Cheers
