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).

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?
