[lxc-users] Share alsa devices in lxc.

[Oz Dror]

Is it possible to used alsa devices in lxc.

in my config file I have ( allow access to the sound devices)

lxc.cgroup.devices.allow = c 116:* rwm

Before the container starts

I create the /dev/snd devices


cd ${LXC_ROOTFS_MOUNT}
mkdir ./dev/snd
cd ./dev/snd
mknod -m 666 controlC0   c   116  2
mknod -m 666 controlC1   c   116  11
mknod -m 666 controlC2   c   116  8
mknod -m 666 hwC0D0   c   116  7
mknod -m 666 hwC1D0   c   116  16
mknod -m 666 pcmC0D0c   c   116  4
mknod -m 666 pcmC0D0p   c   116  3
mknod -m 666 pcmC0D1p   c   116  5
mknod -m 666 pcmC0D2c   c   116  6
mknod -m 666 pcmC1D3p   c   116  12
mknod -m 666 pcmC1D7p   c   116  13
mknod -m 666 pcmC1D8p   c   116  14
mknod -m 666 pcmC1D9p   c   116  15
mknod -m 666 pcmC2D0c   c   116  10
mknod -m 666 pcmC2D0p   c   116  9
mknod -m 666 seq   c   116  1
mknod -m 666 timer   c   116  33

the lxc correctly list the devices with aplay -l or aplay -L

But when I try to play a file

aplay -D ....

I get an error message. The device is not accessible.

Is there anything else that I need to do. Are there any additional
permissions.

Thanks
