VIA’s latest EnvyUSB USB2.0 FS audio controller and high quality High
Definition audio codec(DAC SNR 110dB) are mounted. This supports speakers of 2
channel(2.1 channel), 4 channel, 5.1 channel and has high quality playback
sound of maximum 24bit/48kHz with supporting frequency of 16bit/24bit,
44.1kHz/48kHz. This provides optical output and input terminals which makes
playback even at 24bit/48kHz supporting Blue Ray Control Protection function
and also supports AC3 PassThrough function.


Seem only support two channels 24bit,  only 16bit for 6 channels

How about 4 channels?
