Acer Revo (ION system)+Maverick+5.1 border over HDMI

I've had a stormy partnership with my media centre box. Every upgrade I execute on it appears to bring an all new set of audio concerns (the reverse of my desktop computer where points appear to improve and also far better).

It is a Acer Revo 3600. That is primarily a reduced - end Intel Atom chip with a Nvidia 9400M onboard. Theoretically that is excellent for something like a media centre. Yet having actually simply updated to Maverick, the sound buildings box just intends to supply me stereo sound over HDMI.

The specific arrangement goes : Revo - > Onkyo AV receiver - > LG TELEVISION. The Onkyo box strips off the sound (sustaining 7.1 - - though we are just making use of 6 audio speakers) and also feeds the video clip onto the TELEVISION.

I would certainly such as to reach a factor where Ubuntu assumes it is doing 5.1 over HDMI, upmixing stereo to 6ch and also sustaining DTS/AC3 (via Boxee).

I've had this functioning in the past yet it is truthfully been a little a hacktastrophe.

The audio chip is acknowledged as Nvidia MCP79/7A HDMI in alsamixer if that aids.
