Install backports in sparky to enable ucm/alsa hardware

[pedrolakeside]

A question came from Debian jessie, pe ara the spark based on bullseye, my audio card chtmax98080 is usually activated when installing the kernel backports linux-image-amd64, is a doubt in the folder alsa usually the diver is in /usr/share/alsa/ucm, how to make the alsa / pulseaudio recognize. I'm using the sparky stable lxqt. Thank you
