I installed Batocera on my Chromebook because I had no use for the ChromeOS that was on it.
I am able to get audio through its HDMI port, but I am unable to get its speakers working for some reason.
Below are my audio playback devices. I see that in my dmesg there are no errors from what I can tell about my audio devices. I heard audio when I was in the settings menu CTRL+ALT+F4 editing some settings for my chtmax98090 device, which seems to be the audio device for speakers and the headphone jack.
I enabled every single setting in there, but I still get no audio from the laptop speakers. Not sure what really else to do because I have created the audio config file: /userdata/system/.asoundrc with the below wget command.
wget -O /userdata/system/.asoundrc https://www.batocera.org/users/lbrpdx/asoundrc
At the very least HDMI 0 works when I am running the Chromebook on my TV over HDMI, but I really wish I could get the built-in speakers working.
aplay -l
