I have a new HTPC with XBMC.
Specs:
- Windows 7 Pro 32bit
- Geforce 9500GT with HDMI out and PureHD video Technology
http://www.biostar-usa.com/app/en-us/vga...hp?S_ID=77
- Blue-Ray/DVD/CD Combo Drive
- AM2 Mobo
- AMD Athlon X2 3.0 Ghz Dual Core Processor
- 3GB DDR2 RAM
- 450 Watt Power Supply
- Wireless B/G/N Card
- 32 in 1 Memory Card Reader
Setup:
XBMC--> Sony STR-DA3500ES Receiver --> Sony KDL-XBR5 LCD all three are connected by HDMI 1.3 high speed cables.
Problem:
I am only able to get linear PCM to the receiver, no Dolby Digital/DTS pass through or DD/DTS lights on receiver . I am only able to get a center channel with discrete left, right and rear effects when I switch the receiver to eSURROUND (Dolby Digital PLIIx).
Settings:
Sorry about all of the images, but a picture tells a thousand words.
I searched the forum and the best info I found was this posted by joshuass:
"Don't worry about the supported formats not listing everything. We are actually just passing the sound data through to the receiver for it to decode. And finally, the reason you are seeing stereo and not anything else, is because our hdmi sound chips (which are different than that of the spdif chips) don't support multichannel. With HDMI you have either stereo, or DTS/Dolby pass-through.
I also recommend setting "downmix to stereo" on too. That way, if you play any multichannel videos that aren't in AC3 or DTS, it will downmix those to stereo so you can atleast still listen to it. Multichannel AAC files do not play right throug HDMI since they can't be decoded by the receiver".

"Unless something has changed recently, I don't believe you should need to do anything with advancedsettings in windows. If you choose analog audio, XBMC will simply decode the DTS and AC3 sound and send the results data as a PCM stream to your soundcard. Your HDMI card should be able to handle this, as should any receiver equipped for PCM sound, which should be any receiver that accepts and HDMI input. The AC3 and DTS lights won't pop up, but you should get 5.1 sound".
I have tried the advice in the above 2 posts and have only been able to get linear PCM, no Dolby Digital/DTS pass through. Also neither of the 2 test buttons will work. I can only get a 44khz test chime of I run a optical cable from my LCD monitor to my receiver. I have tried several movies off of my HD.
Could it just be the case of a simple overlooked setting and not a bug?
