BB not prompting my receiver to switch between AC3 and DTS audio
I have an HDMI output to my TV and an optical audio cable out to my Denon 1905 receiver from my BB. I have the audio setting set to "All outputs" on my BB. On my receiver, I have the audio coming in from my BB set to "Standard", meaning that it should switch to either AC3 or DTS depending on the video source. In the past, with my WDTV player, if I play a MKV with DTS or AC3 audio, my receiver will automatically switch to DTS or AC3 accordingly. Now with the BB, the audio setting never switches on my receiver. It just keeps the audio setting from the last movie I played. I would have to press the "Standard" button on my Denon remote to switch to the other audio decoding setting.
Is anyone else experiencing this issue?

Yes when you set it to all devices it seems to mess with how the sound is output via opticle/hdmi. I think it must be doing some down mixing otherwise if your TV was sent a DTS signal it would get white noise becuase it doesnt have the capability to decode a DTS signal.
If you want it to work as you want and how it should then set it to opticle out only or hdmi out only depending on how you are connecting it to your amp. Not great I know as you have to have your amp on to listen to the boxee all the time. Hopefully this will be fixed for the next update

Yeah, when you set it to "all", the Boxee Box currently has to output in stereo PCM over all connections so that the audio is decoded into a format that can be output over the stereo RCA connections (red and white) on the back of the Box. To get surround audio, you have to use either SPDIF or HDMI, and to get HD audio (24-bit, 96khz), it's HDMI only.
I honestly don't know if this is a limitation of the hardware or the software at this point. There have been hints of optimism about getting stereo PCM over the RCA connectors at the same time that surround is output over one or both of the digital connections, but I haven't seen any concrete or confident statements about this from the Boxee team.
