Sharing sound between users on wheezy.
Good time of the day, Raffaele.
I could not answer on Your last letter so I have started a new thread.

The problem now is that I can not achieve multi user SB access. Or
rahter I would say it is but working strange way. - I can play FLAC w/
mplayer2 under one user, at the same time I can pause the playing and
start watching movie w/ mplayer2 under another user. - All works. But
in case no app.s are using SB, I run under yet another user jackd, run
an MIDI editor MusE, then quit it (jackd is still running), I start
mplayer2 for FLAC under the first user - it refuses to play until I
kill jackd from under the third user. Please, do not ask me for the
configuration of the three users - just let's suppose this is the
initial situation.
In other words I see: 2 mplayer2 under 2 users at the same time can
share SB, whereas 1 mplayer2 and 1 jackd under 2 users can not share SB.
All these three users are in the audio group that has its record in
/etc/security/limits.d/audio.conf
/etc/asound.conf :
# This is commented out because if enabled - PCM ceases to work, only
Master works; whereas when disabled - both work. #pcm.!default {
# type plug
# slave.pcm "dmixer"
#}
pcm.dsp0 {
type plug
slave.pcm "dmixer"
}
pcm.dmixer {
type dmix
ipc_key 1024 # the key must be unique
ipc_key_add_uid 0 #
Multiusage ipc_perm 0660 # permissions - octal notation
slave {
pcm "hw:0,0"
period_time 0
period_size 2048
buffer_size 8192
rate 44100
}
}
ctl.dmixer {
type hw
card 0
}
Do You have any comments on my setup?
Thanks for Your help.
Sthu.
