No headphone sound on Asus C302 (Cave)

[lbilli]

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?
