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 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:
So this really isn't a Raspberry OS question so much as a general Linux question.
ALSA lib confmisc.c:855:(parse_card) cannot find card '0'
The answer must involve user groups/permission or something in the static configuration, because /dev, /proc, /sys, and /tmp are all mount --rbind to the main system outside the CHROOT. Any clue what I should try to get the sound operational within the CHROOT?
