8 Channel ALSA Output

[AlexS]

Hi,

I wanted to ask, if it is possible to get the full 8 channel output over HDMI with the alsa driver? It should be possible because the openmaxil hallo_audio sample does with with 8 channels. But the alsa driver does not work with more then 2 channel (max_channel is set to 2 in source code).

I currently have no possibility to compile the raspberry kernel myself to check, if it is possible with simply changing the max_channel definition.


Thanks,
Alex

I believe the HDMI sound output does not use ALSA so surround sound should be possible.

I want explicit use the alsa driver. I want to use pulseaudio to output sound. The output via hdmi is basicly working but only with two channels.
