Surround sound

I'm trying to get 5.1 surround over HDMI working. So far only 2.0 is working. The rear speakers and sub don't work, and for the center it uses both left and right. I installed PulseAudio, and followed this tutorial, but no succes. Is a driver update needed?

    Hi Pieeeeeee,

    We haven't tried this, but since the Linux HDMI support was never announced as feature-complete, it isn't entirely surprising that 5.1 wouldn't work out of the box. We'll let you know if we find anything new on this.


    P.S. In the meantime, in case anyone needs a starting point: this bit of code from the Cherry Trail audio patches seems to suggest 2.0 would be selected over a surround setup? I don't have expertise with kernel i915/sound code, so I might well be drawing the wrong conclusion here.

    I'm a software developer, but my linux knowledge is low, so don't really know what to do with the code.
    I think surround is essential, I want to use it as a Kodi mediaplayer. If I'm happy with the result, I'm buying 2 or 3 more for other people. Switching to Windows might be a solution, but I'd rather stick to legal software.
