I have a S/PDIF out STB and have it connected to the Slingbox PRO HD.
No 5.1, only 2 channel audio.
This is even with the stand alone 2.0.4 player with the digtial audio out option selected, and dolby digital audio out selected from the STB, and verified Dolby Digital 5.1 content.
Of course, there is no digital audio selection option with the browser based plug in players.
Any help or answer would be greatly appreciated.
You mean 5.1 from the standalone Slingplayer program? No you won't get 5.1 audio from the Slingplayer program.
