host: Ubuntu 18.04 LXD/LXC 3.0.3
I am trying to use ALSA in my ubuntu 18.04 container. ALSA on host works. I have seen this post but it doesn't work for me.
My configuration:
lxc config set mycontainer raw.lxc "lxc.cgroup.devices.allow = c 116:* rwm"
lxc config set mycontainer raw.lxc "lxc.mount.entry = /dev/snd dev/snd none bind,optional,create=dir 0 0"
aplay: aplay -l aplay: device_list:270: no soundcards found..
ALSA on the host works perfectly well.
What else do I need to do to make it work?
I guess, I have managed to get it working. Found this post
lxc config device add <container> pcmC0D2c unix-char path=/dev/snd/pcmC0D2c
I have added all devices listed in/dev/snd:
hwC0D0 hwC0D2 pcmC0D0c pcmC0D0p pcmC0D10p pcmC0D1p pcmC0D2c pcmC0D3p pcmC0D7p pcmC0D8p pcmC0D9p seq timer
It is important to add seq and timer, as well.
