No headphone sound on Asus C302 (Cave) #133

Closed lbilli closed 1 month ago

lbilli commented 3 months ago

After running the script on an Asus C302CA (Cave) with openSUSE Tumbleweed, I get:

builtin speakers work great
builtin mic works, though low volume
headphone mic works great
headphone speakers produce no sound, just a single click when trying to play anything

Also, when inserting the jack, the headphone mic gets automatically selected, whereas the headphone speakers are not.

The only log message that looks it might be related: kernel: nau8825 i2c-10508825:00: No 'mclk' clock found, assume MCLK is managed externally

Any suggestions?

As I saw in a recent commit an update to the avs topology for nau8825, I decided to give it a try and indeed it mostly fixed my issue. Headphones sound is now working, the only minor issue being a fairly audible click when sound starts.

So, I'm wondering what's the difference with the nau8825 topology shipped in the 2024.02 release of thesofproject/avs-topology-xml.

Finally, while I was fiddling with the ucm conf files for avs_nau8825, I was wondering if, in the Mic section, JackControl should point to Headset Mic Jack instead of Headphone Jack.

I'm not sure what causes the click when playback starts. The JackControl in Mic has been fixed to use the correct control.
