Hello.

I would like to have snd-dummy working inside a VPS. I tried to make device nodes and changed permissions to rw.

Inside the VPS:

On the HN:

rc04:~# ls -lR /dev|grep audio
crw-rw-rw- 1 root audio    14,   4 2009-05-27 04:32 audio
crw-rw-rw- 1 root audio    14,   3 2009-05-27 04:32 dsp

crw-rw-rw- 1 root audio 116,  0 2009-05-27 04:32 controlC0
crw-rw-rw- 1 root audio 116, 24 2009-05-27 04:32 pcmC0D0c

crw-rw-rw- 1 root audio 116,  1 2009-05-27 04:32 seq
crw-rw-rw- 1 root audio 116, 33 2009-05-27 04:32 timer

snd-dummy works good on the HN, but not in the VPS.

This is Debian Lenny Linux rc04 2.6.26-2-openvz-amd64 #1 SMP Wed May 13 16:46:17 UTC 2009 x86_64 GNU/Linux

HN is 64 bit OS and VPS is 32 bit Debian Lenny.

Looks like I need to make something not only with /dev, but with /proc/asound also.

Looks like it was made deliberately:

diff-ve-proc-sound-20071015 
Patch from Evgeny Kravtsunov <emkravts@openvz.org>
 [PATCH] hide global /proc/asound entry from VE

Is there a [simple] way to make /proc/asound in the VE?

The simple answer is: you can't. I used vserver to use sound from VPS.

So, I can't use snd_dummy on openVZ virtual mashine...

I want to run skype and asterisk in the virtual environment to be able to call skype users via Asterisk. What do you advise?

Formally, you can use /dev/snd in OpenVZ, but skype requires /proc/asound also. I successfully used skype (with snd-dummy) with asterisk in VServer.

Browsing the net, I'm finally inconclusive whether it is possible to get ALSA running inside a container or not.

I'd like to attach my speakers to my server and have a VE for playing music, i.e. I just do not want to depend on a specific Workstation to be running to listen to music.

Does anyone have a viable solution to run some music player inside a VE? If so, is there a HOWTO available?

Otherwise, can someone definitely state that OpenVZ does not allow running a music player?

Regards,
- lars.
