I installed a new PCI based soundcard in my PC. It has 8 S/PDIF based I/O pairs with each line numbered 1 to 8 for input as well as output. And I'm trying to use lines 3-8 for input (mics) and 3-8 for output (play) in stereo with :
- line 3 + line 4 = channel 1 (both input and output),
- line 5 + line 6 = channel 2 (both input and output),
- line 7 + line 8 = channel 3 (both input and output).
So, I created the following .asoundrc
:
pcm.!default {
type plug
slave {
pcm "hw:1,0"
}
}
ctl.!default {
type hw
card 1
}
pcm.play_out_44 {
type dmix
ipc_key 1201
ipc_key_add_uid true
slave {
pcm "hw:1,0"
channels 2
rate 44100
format S32_LE
buffer_size 4096
period_size 1024
}
}
pcm.rec_in_44 {
type dsnoop
ipc_key 1210
slave {
pcm "hw:1,0"
channels 2
rate 44100
buffer_size 4096
period_size 1024
}
}
pcm.outch1 {
type plug
slave {
pcm "play_out_44"
bindings {
2 2
3 3
}
hint.description "PCI Card Stereo output/playback channel 1 (from output ports 3 & 4)"
}
}
pcm.inch1 {
type plug
slave {
pcm "rec_in_44"
bindings {
2 2
3 3
}
hint.description "PCI Card Stereo input/capture channel 1 (from input ports 3 & 4)"
}
}
pcm.outch2 {
type plug
slave {
pcm "play_out_44"
bindings {
4 4
5 5
}
hint.description "PCI Card Stereo output/playback channel 2 (from output ports 5 & 6)"
}
}
pcm.inch2 {
type plug
slave {
pcm "rec_in_44"
bindings {
4 4
5 5
}
hint.description "PCI Card Stereo input/capture channel 2 (from input ports 5 & 6)"
}
}
pcm.outch3 {
type plug
slave {
pcm "play_out_44"
bindings {
6 6
7 7
}
hint.description "PCI Card Stereo output/playback channel 3 (from output ports 7 & 8)"
}
}
pcm.inch3 {
type plug
slave {
pcm "rec_in_44"
bindings {
6 6
7 7
}
hint.description "PCI Card Stereo input/capture channel 3 (from input ports 7 & 8)"
}
}
As mentioned here, I created a new dmix
type to suit my configuration. But when I try to open Audacity
to try and play and capture, none of inch1
, inch2
, inch3
, outch1
, outch2
, outch3
are available in the recording device or playback device list!
How do I modify or create a .asoundrc
for stereo play and stereo capture on my device?
