I'm doing something that might seem like a bit of an odd/strange thing to do, but it does (mostly) work.
I'm running graphical programs within a CHROOT setup into a Raspberry Pi OS LITE (debian) image. X-server and ALSA Sound Services, etc. are all working fine outside the CHROOT (device drivers are all loaded, etc), but within the CHROOT, the sound card is not available:
ALSA lib confmisc.c:855:(parse_card) cannot find card '0'
The answer must involve user groups/permission, environment, missing packages, or something else in the system configuration, because /dev, /proc, /sys, and /tmp are all mount --rbind to the main system outside the CHROOT and fully available to the application. If something fundamental has changed since Kernel 4.15 with sound, that could be it too (OS within CHROOT is configured and intended to work with newest kernel).
Any clue what I should try to get the sound operational to programs within the CHROOT?
