UCM

UCM copied to clipboard

I installed Manjaro Deepin 18.0.3 on my chromebook (Toshiba Chromebook CB35-B3340) and it’s mostly working all fine but I have no sound output. In deepin settings tapping on both available options doesn’t change anything. The card I have in my laptop is chtmax98090. Googling a bit led me to this page: https://wiki.archlinux.org/index.php/Acer_CB3-131_Chromebook

I’m trying to follow the instructions under the hardware support section but when I run the command alsaucm -c chtmax98090 set _verb HiFi set _enadev Speakers I get the errors:

ALSA lib utils.c:63:(uc_mgr_config_load) could not open configuration file /usr/share/alsa/ucm/GOOGLE-Swanky-1.0-Swanky/GOOGLE-Swanky-1.0-Swanky.conf
ALSA lib parser.c:1425:(load_master_config) error: could not parse configuration for card GOOGLE-Swanky-1.0-Swanky

How can I fix this?

those are misleading warnings that aren't important. This was well-intended to allow for platform-specific files matching the DMI name but it will fallback to using the regular card name and UCM ops. I haven't tested these setting in 1 year or so but there's no reason why they need a change.

I see. So I should proceed with the rest of the steps without concern for these messages?
