Hi
Firstly many thanks for your guide!
Im having a few issues with output from the speakers, let me describe my setup:
Acer Revo - Nvidia GPU with HDMI out
Bose V30 surround sound with HDMI inputs.
I followed the guide and recieved some errors when using amixer:
/usr/bin/amixer -q -c 0 sset 'IEC958 default pcm',0 unmute/usr/bin/amixer -q -c 0 sset 'IEC958',0 unmute && /usr/bin/amixer -q -c 0 sset 'IEC958',1 unmute
amixer: Unable to find simple control 'IEC958 default pcm',0
on looking in alsamixer i do not have that channel/device, my selected device is:
Card: HDA Nvidia
Chip: Nvidia MCP7A HDMI
the out put of aplay is:
aplay -l
Code:
