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/sound/soc/intel/boards/bytcht_es8316.c?h=next-20180718&id=a03bdaa565cbf23fa86697727a7d2bf1465e7a03) 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 ---------- Forwarded message --------- From: Mark Brown <broonie@xxxxxxxxxx> Date: Thu, Sep 27, 2018 at 3:14 PM Subject: Re: Help with sound on Cherry Trail laptop with ES8316 sound chip To: Sundar Nagarajan <sun.nagarajan@xxxxxxxxx> Cc: Daniel Drake <drake@xxxxxxxxxxxx>, David Yang <yangxiaohua@xxxxxxxxxxxxxxxx> On Wed, Sep 26, 2018 at 12:53:44PM -0700, Sundar Nagarajan wrote: > )I found your email from the kernel.org commit log for the > bytcht_es8316.c driver > (https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/sound/soc/intel/boards/bytcht_es8316.c?h=next-20180718&id=a03bdaa565cbf23fa86697727a7d2bf1465e7a03. > I have (separate) issues with two different Cherry Trail laptops that > have the ES8316 chipset.

You'd be best contacting the Intel maintainers about x86 specific issues: INTEL ASoC DRIVERS M: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> M: Liam Girdwood <liam.r.girdwood@xxxxxxxxxxxxxxx> M: Jie Yang <yang.jie@xxxxxxxxxxxxxxx> L: alsa-devel@xxxxxxxxxxxxxxxx (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@xxxxxxxxxxxxxxxx) 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.
