Hi,
On a Skylake based Samsung Tabpro S tablet I am having two alsa issues on 4.7.0 and 4.8.0-rc5:
- no output on speaker with any possible configuration, but audio over headphone jack works - playback speed/pitch is doubled (audible over headphones)
Sound works fine in Windows obviously, but rebooting from Windows to Linux (as opposed to cold boot) doesn't seem to have any influence on these issues.
I've tried modprobing with all the various ALC model quirks to no avail. I've tried toggling various options with amixer (Auto Mute, various speaker related values with amixer cset) and even played with hda-analyzer.py but was unable to get anything from the speakers whatsoever.
Since this is Sunrise Point-LP HD Audio, I realize it's fairly new and there may be new quirks required to make this work. I've attached alsa-info.txt; I'm happy to patch and test if someone can give me some direction on what to try, but any help would be much appreciated.
Thanks.
