Hello,

I have (separate) issues with two different Cherry Trail laptops that have the ES8316 chipset for sound.

I already posted the following issues on Pierre Bossart's Intel UCM repository(https://github.com/plbossart/UCM):

Issue 42: RDP Thinbook 1430 laptop (ES8316): Can't select between built-in speakers and headphone output (https://github.com/plbossart/UCM/issues/42)

Pierre's input was as follows: The UCM file you are using gives the clue already: #Codec IC has only 1 analog out, switching SPK/HP is done externally, #probably by means of some analog switch controlled by gpio There is nothing we can do at the UCM level, this has to be handled at a lower level (i.e. the kernel)

In addition, on a different laptop, I have a different problem with the ES3816 chipset.

Issue 41: No sound on speakers on Chuwi Hi12 laptop - headphone sound works (es8316) (https://github.com/plbossart/UCM/issues/41)

I reached out to Mark Brown, Daniel Drake and David Yang who were listed on the kernel.org commit for the ytcht_es8316.c driver (https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/s...) and Mark suggested reaching out to you folks.

What is the right place for me to post my issues to get your ideas and help? I have access to these machines, and I can compile kernels and perform testing, collect logs etc.

Regards, Sundar

He's on sabbatical at the minute FWIW.

You'd be best contacting the Intel maintainers about x86 specific issues:

INTEL ASoC DRIVERS M: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com M: Liam Girdwood liam.r.girdwood@linux.intel.com M: Jie Yang yang.jie@linux.intel.com L: alsa-devel@alsa-project.org (moderated for non-subscribers) S: Supported F: sound/soc/intel/

That includes Pierre but also a few other people, hopefully at least one of them will be able to help or point you to someone who can. You should also copy in the alsa-devel list (alsa-devel@alsa-project.org) in case someone else can help and so people can google the discussion later, though that'll mean your e-mail address ends up in the archives so you might not be happy with that.
