Hello everybody,

The 9632 is playing very fine on my system but I have allways to quit my player (deadbeef) to play somethings from the browser (chromium) with flash! The messages in xsession.errors are: dmix can't open slave! I have no idee how to proceed...Thank you for any wellcomed help.

System infos:

Advanced Linux Sound Architecture Driver Version 1.0.23.

I use the outputs 11-12 to the analog amplifier. The onboard sound card is off in the bios.

Re: Ubuntu RME 9632 can't get 2 apps playing sumiltaneously!?

Ok FINALLY I got it working fryingpan

I can now play simultaneously: Flash player through Chromium, vlc (radio stream) and Deadbeef!!! This is the .asoundrc file that I found here http://ubuntuforums.org/archive/index.p … 59022.html and looks like that:

pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm {
type dmix
ipc_key 5678292
ipc_gid {
@func refer
name defaults.pcm.ipc_gid
}
ipc_perm {
@func refer
name defaults.pcm.ipc_perm
}
slave {
pcm {
type hw
card "DSP"
}
format "S32_LE"
rate 48000
channels 12
buffer_size 2048
period_size 1024
}
}
}
capture.pcm {
type plug
slave.pcm {
type dsnoop
ipc_key 5678291
ipc_gid {
@func refer
name defaults.pcm.ipc_gid
}
ipc_perm {
@func refer
name defaults.pcm.ipc_perm
}
slave {
pcm {
type hw
card "DSP"
}
format "S32_LE"
rate 48000
channels 12
buffer_size 2048
period_size 1024
}
}
}
}

The only things that should be done in the players (deadbeef, vlc) is to use default device and alsa output. I hope it will help...
