Hi all - my first post, so please be gentle.
Firstly, congrats on the great product. I spent may years using a realmagic Xcard and associated TVEdia interface, but have now upgraded to a flat panel display, so can now go native digital. Interface (with Streamed MP ) is just spectacular.
Now to my problem....
The PC I have doesn't have an SPDIF out, so I have gone down the route of buying a USB -> SPDIF device. In fact, I've ended up with two:
M-Audio Transit
Maplin Sound Box
What I'm trying to achieve is bitperfect output for 2 channel PCM and DD/DTS passthrough for DVDs. Don't have any DTS audio discs, so it's all standard DVD-video soundtracks.
I can get things working with the M-Audio transit, but the problem is I can only choose between PCM and passthrough modes - there is no auto-detect, so it's a manual reconfigure which is not practical. If I did auto-detect, it would be ideal.
The Maplin Sound Box doesn't come with any drivers and registers itself as a "USB Audio" device. It works to some extent (i.e. I get sound), but I can't get it to passthrough DTS/DD - just appears as stereo on my home theater receiver. In MediaPortal, I get 4 options for audio renderer (USB Audio, Default DirectSound Device, Default WaveOut Device, DirectSound: USB Audio).
Have read lots online about kmixer, asio and the various driver options, but am still a bit confused. Trial and error hasn't got me anywhere either. So far, I have tried:
Audio decoder = AC3filter (configured for SPDIF passthrough of DD/DTS)
Audio decoder = ffdshow Audio Decoder (configured for SPDIF passthrough of DD/DTS)
Audio renderer = USB Audio
Audio renderer = DirectSound: USB Audio
Enable/disable "Use AC3 filter (for some soundcards using SPDIF)"
PureAudio plugin
Have also through about trying ASIO4ALL, but not sure if that is the right road to go down.
Also, I have installed PowerDVD in order to test another player - it doesn't even recognise that I have an SPDIF device in my configuration, which is odd. Windows Media Player does the same as Mediaportal in terms of stereo-only output.
Am I flogging a dead horse? Should I be expecting a vanilla USB->SPDIF dongle to do what I'm after, or do I need to look for a more advanced version of the M-Audio transit which does have auto-sense capability? hagusb perhaps?
Any help much appreciated
