Kernel reports "no soundcard". Presumably, this is why I don't have sound. Let me dive right in with details:
FWIW, more about this hardware: -- It's a cheap laptop, from newegg, Ipason MaxBook P1X, 4-core Intel Celeron, 12GB RAM, great price.
and no linux support. Yay.
see https://github.com/thesofproject/linux/wiki/ES8336-support
Good news: The driver seems to be talking to the sound card. Bad news: No sound, except for a faint pop when muting, and when the driver closes the card. No error messages in dmesg.
So: -- I git cloned https://github.com/thesofproject/linux/ and git checkout es8336-v5.19 -- make menuconfig to enable the es8336 modules, then make; make modules_install etc. -- copy the firmware into place as suggested by the wiki page -- enable dynamic debug as suggested by wiki pages -- reboot.
I see lots of debug messages in dmesg. None of them appear to be warnings or errors. But /usr/bin/speaker-test does not result in any sound. It does cause some dmesg messages to print when started, but none appear to be errors. Some more messages print when its stopped. /usr/bin/alsabat seems to think everything is OK.
The driver seems to be responsive, in that mixers and volume controls seem to actually talk to the driver, and "do things".
I'm stumped as to what to try next. Recommendations?
Should I be using github issues for this, instead of email? I'm thinking the answer is yes, I should. It's somehow easier to track issues via github.
