The S905x allow up to 8ch output. That means, i guess, that he can process such data according to the following cases :
- Multichannel file on a local or distant storage (access through any wire or wireless network connection, even USB). (Am i wrong assuming this ?)
But you confirmed that the board input through the i²S bus can't handle more than 2 audio channel (for example through an S/PDIF connector).
My main goal was to use a VIM board to process audio data to improve my speakers response (audio filters, fft, convolutions, fir, iir ....) instead of a dedicated DSP board, coming through the TV or through my blu ray player.
So even if I would be able to handle any musical content, that won't be the case for home cinema content, where I would have to downmix the 5.1 stream into stereo. My last question was then to know if, besides the i²S bus, there would be any other gate/feature i could use to be able to send the audio multichannel stream of a movie to the Vim ?
