Thread: Channel mapping m-audio fast track ultra

so have managed m-audio fast track ultra seen , send tones out of outputs.

however, still having difficulty mapping channels correctly in .asoundrc file. appreciated.

here issues:
card reads 7.1 , jack fails connect when set actual 6 channels has. (card has 6 analog out , 2 digital).
audio outputs in both supercollider , using speaker-test. when multichannel seems output channel 1.

have latest alsa compiled.

aplay -l

code:

**** list of playback hardware devices ****  card 0: intel [hda intel], device 0: alc663 analog [alc663 analog]    subdevices: 1/1    subdevice #0: subdevice #0  card 0: intel [hda intel], device 1: alc663 digital [alc663 digital]    subdevices: 1/1    subdevice #0: subdevice #0  card 0: intel [hda intel], device 3: hdmi 0 [hdmi 0]    subdevices: 1/1    subdevice #0: subdevice #0  card 1: ultra [fast track ultra], device 0: usb audio [usb audio]    subdevices: 1/1    subdevice #0: subdevice #0

figured out. had working along, hadn't gone alsamixer in command line , muted correct channels. each channel had 8 active , had make sure each channel had it's own channel unmuted.
