Dear Colleagues,

I have installed a fresh Fedora 9, and I have an Echo Layla3G (pci) card. All I had to do was install the firmware, and it to playback out of Layla headphones. This device has other Outputs, how I can I easily select the other channels for playback?

aplay -l show these (along withthe Intel HDA for the built-in audio device): card 1: Layla3G [Layla3G], device 0: Analog PCM [Layla3G] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7

so is it possible to type: aplay -D hw:1,0 thewavefile.wav and specify the subdevice? Or do I need to specify in my .asoundrc file an alias? with -D hw:1,0 I get sound out of Layla's headphone port only.

If you have links to useful howtos or documentation, please let me know.
