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:



pcm.!default

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?

      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?

      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:



      pcm.!default 
       type plug
       slave 
       pcm "hw:1,0"
       


      ctl.!default 
       type hw
       card 1


      pcm_slave.pci-sc 
       pcm "hw:1,0"

       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:



      pcm.!default 
       type plug
       slave 
       pcm "hw:1,0"
