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 input lines 3, 5, 7 for input (mics) and output lines 3, 5, 7 for output (play) in mono with :
- line 3 = channel 1 (both input and output),
- line 5 = channel 2 (both input and output),
- line 7 = channel 3 (both input and output).
So, I created the following `.asoundrc`:
Code:
pcm.!default {
type plug
slave {
pcm "hw:1,0"
}
}
ctl.!default {
type hw
card 1
}
pcm_slave.pci-sc {
pcm "hw:1,0"
channels 8
rate 44100
buffer_size 4096
period_size 1024
}
pcm.outch1 {
type plug
slave.pcm {
type dshare
ipc_key 1111
slave pci-sc
bindings [ 2 ]
hint.description "PCI Card output/playback channel 1 (from output port 3)"
}
}
pcm.inch1 {
type plug
slave.pcm {
type dsnoop
ipc_key 1111
slave pci-sc
bindings [ 2 ]
hint.description "PCI Card input/capture channel 1 (from input port 3)"
}
}
pcm.outch2 {
type plug
slave.pcm {
type dshare
ipc_key 1111
slave pci-sc
bindings [ 4 ]
hint.description "PCI Card output/playback channel 2 (from output port 5)"
}
}
pcm.inch2 {
type plug
slave.pcm {
type dsnoop
ipc_key 1111
slave pci-sc
bindings [ 4 ]
hint.description "PCI Card input/capture channel 2 (from input port 5)"
}
}
pcm.outch3 {
type plug
slave.pcm {
type dshare
ipc_key 1111
slave pci-sc
bindings [ 6 ]
hint.description "PCI Card output/playback channel 3 (from output port 7)"
}
}
pcm.inch3 {
type plug
slave.pcm {
type dsnoop
ipc_key 1111
slave pci-sc
bindings [ 6 ]
hint.description "PCI Card input/capture channel 3 (from input port 7)"
}
}
But with the above configuration, when I try to open `Audacity` to try and play and capture, only `inch1`, `inch2`, `inch3` are available but `outch1`, `outch2`, `outch3` are not available in the recording device or playback device list!
Also, I tried creating `.asoundrc` as mentioned
here as follows as well:
Code:
pcm.!default {
type plug
slave {
pcm "hw:1,0"
}
}
ctl.!default {
type hw

}
pcm_slave.pci-sc {

This time around the same issue comes up - only `inch1`, `inch2`, `inch3` are available but `outch1`, `outch2`, `outch3` are not available in the recording device or playback device list! The above works fine for USB sound card. I've tried and tested. Shouldn't this work for PCI based soundcard as well? What dependencies on hardware should I be aware of?
What could be going wrong here? How to fix this?
