Hi,

the first situation is what also works for me right now; software 
decoding and 48kHz/2ch/16bit output. Second test is still using software 
decoding and the 3th and 4th tests use the pass through.
I tried the same settings on my setup and get the same messages but no 
audio playback. At least I now know these messages are OK and the 
pass-through part does work on other setups. Now just have to figure out 
what's going wrong on the RS690 :-\ . I have no other tests at the moment.

Thanks,
Christiaan.
