No sound trough fiber optic
I have ax360 headphones that support 5.1 and I'm trying to make em wirk trough fiber optic, but i get no sound. If I use the normal pc connectors, I have sound, but only stereo.
I'm using Slackware 12.1 and have a realtek alc655 sound chip integrated in my motherboard(gigabyte 7n400 pro rev2)
I already tried almost every possible combinations in alsamixer without success and i'm sure everything i need is unmuted.
I managed to get stereo sound with the fiber optic with this .asoundrc config file, but I can't control the volume and even if i mute the master the sound is still playing (not all sound play, only the kde sounds and a video using this codec: [faad] AAC (MPEG2/4 Advanced Audio Coding))
Code:
# Override the default output used by ALSA.
# If you do not override the default, your default
# device is identical to the (unmixed) analog device
# shown below. If you prefer mixed and/or digital
# output, uncomment the appropriate four lines below
# (only one slave.pcm line).
### Currently set w/digital-hw as the default output,
### comment out this entire section to use unmixed
### analog as your default

I searched for about 4 hours and I'm out of ideas, so I hope one of you have one. |
