Lets see.

a9042defa29a01cc538b742eab047848e9b5ae14 -- works ok.
ce38207f161513ee3d2bd3860489f07ebe65bc78 --

alsactl: set_control:1328: failed to obtain info for control #229 (No
such file or directory)

and broken in-call speaker. So this merge breaks stuff:

commit ce38207f161513ee3d2bd3860489f07ebe65bc78
Merge: a9042de 995c6a7
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Wed Dec 14 11:14:28 2016 -0800

    Merge tag 'sound-4.10-rc1' of
    git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
...
      Below are some highlights:

      ASoC:
             - support for stereo DAPM controls
	            - some initial work on the of-graph sound card
		           - regmap conversions of the remaining AC'97
      drivers
             - a new version of the topology ABI; this should be
      backward
               compatible
	              - updates / cleanups of rsnd, sunxi, sti,
      nau8825, samsung, arizona,
               Intel skylake, atom-sst
	              - new drivers for Cirrus Logic CS42L42, Qualcomm
      MSM8916-WCD, and
               Realtek RT5665
...

Best regards,
									Pavel
