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?

我想，我已经设法让它工作了。找到这个帖子

lxc config device add <container> pcmC0D2c unix-char path=/dev/snd/pcmC0D2c

我添加了以下列出的所有设备/dev/snd：

hwC0D0 hwC0D2 pcmC0D0c pcmC0D0p pcmC0D10p pcmC0D1p pcmC0D2c pcmC0D3p pcmC0D7p pcmC0D8p pcmC0D9p seq timer

添加seq和也很重要timer。
