Hi
I've got problem. I have 5 sound cards installed as follow :
0 [Juli ]: ICE1724 - ESI Juli@
ESI Juli@ at 0x10e0, irq 22
1 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0x88320000 irq 49
2 [Live ]: EMU10K1 - SB Live! Value [CT4832]
SB Live! Value [CT4832] (rev.8, serial:0x80271102) at
0x10c0, irq 18
3 [CODEC ]: USB-Audio - USB Audio CODEC
Burr-Brown from TI USB Audio CODEC at
usb-0000:00:1d.1-2, full speed
4 [S51 ]: USB-Audio - SB X-Fi Surround 5.1
Creative Technology SB X-Fi Surround 5.1 at
usb-0000:00:1d.0-1, full speed
Audio 3 and 4 are USB cards. Now, i would like to play on each cards from
multiple sources in one time.
I read, that i should use dmix. So, i confgured /etc/asound.conf for dmix :
pcm.mixusb {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0666 # mixing for all users
slave {
pcm "hw:3,0"
period_time 0
period_size 1024
buffer_size 8192
rate 44100
}
bindings {
0 0
1 1
}
}
pcm.dsp0 {
type plug
slave.pcm "mixusb"
}
pcm.!default {
type plug
slave.pcm "mixusb"
}
pcm.default {
type plug
slave.pcm "mixusb"
}
ctl.mixer0 {
type hw
card 3
}
It works as ia expected, on hw:3,0 i can play from some sources in the same
time.
So, i wanted to add another card with this configuration.
There is my config file after changes :
pcm.mixusb {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0666 # mixing for all users
slave {
pcm "hw:3,0"
period_time 0
period_size 1024
buffer_size 8192
rate 44100
}
bindings {
0 0
1 1
}
}
pcm.dsp0 {
type plug
slave.pcm "mixusb"
}
pcm.!default {
type plug
slave.pcm "mixusb"
}
pcm.default {
type plug
slave.pcm "mixusb"
}
ctl.mixer0 {
type hw
card 3
}
pcm.mixjulia {
type dmix
ipc_key 2048
ipc_key_add_uid false
ipc_perm 0666 # mixing for all users
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 8192
rate 44100
}
bindings {
0 0
1 1
}
}
pcm.dsp0 {
type plug
slave.pcm "mixjulia"
}
pcm.!default {
type plug
slave.pcm "mixjulia"
}
pcm.default {
type plug
slave.pcm "mixjulia"
}
ctl.mixer0 {
type hw
card 0
And now, all my sources plays on mixjulia , although some sources are
configured to play on mixusb
I remove from config file sections pcm.default ( i dont want to play as
default ), and ctl.mixer ( i read
that this section is not needed). It doesnt help.
Any idea ? I will be grateful for any help.
regards

ps. My system is Ubuntu 12.04.4 LTS server edition, Alsa version 1.0.24
