I have been using XBMC for a long time and to clarify what is going on.

Using XBMC Dharma RC2 (or any version for that matter of Dharma) -- If I have 5.1 Audio Selected (Digital Out via. TOSLINK) DTS/AC3 Enabled files will play but it does not appear to pass audio to my receiver.

While playing Stereo .AVI -- it works fine and I get audio same exact settings.

Now here is where it gets strange -- if I turn 5.1 to 2.0 and disable DTS/AC3 my .mkv's play fine (I found this via. a post @ XBMCFreak but w/o an explanation of why).

Anyone have any suggestions -- 9.11 works fine out of the box same hardware...

Thanks for any input on this.

Also this is the Live version.

what hardware? what are your detailed xbmc audio settings (passthrough etc.)?

p.s. explanation: you enabled downmixing

[pfriederichs]

Using a generic (Rocketfish) 7.1 audio card (I believe it uses the X-Fi chipset).

Audio settings are both set to IEC (CA0106) / Passthrus: IEC(CA0106).

My receiver supports AC3/DTS and like I said initially 9.11 out of the box works 100% fine w/ .avi, .mkv, stereo, dts, etc...

Whatever is going on started with Dharma -- thanks for any help!

hmmmm I could use some help here, but according to the aplay output, I'd try entering

plughw:1,0

up to

plughw:1,3

manually into the corresponding fields in audio settings until surround passthrough works. keep in mind that without further editing you will lose menu sounds.

but there are more experienced audio experts in this board. at least we have all the info we need now.

I'm having the exact same problem! Upgraded to newest version and lost digital passthrough on my ca0106. Did you ever get it figured out?
