first of all, great site guys
ok heres what im using, Vista Home Premium 64bit with sp1
Asus P5N-E SLI motherboard which has a realtek ALC883 sound chip (a 7.1 chip but its limited to 5.1 on this board as standard) im using the Coax output on the back which is contected to my 5.1 sound system. and im using the R1.89 realtek HD audio driver codec (have tryed R1.88,R1.87a,R1.87, and the ones that came with the motherboard R1.57)
Now hes the problem, i can only get 5.1 sound when i play a DVD in WMP, Media center and the realtek digital out put test works too. But when i try playing games (crysis,call of duty 4 and so on) im stuck with dolby pro logic 2.1 and i also can't seem to see the digital output on the realtek manager either no matter what version i use. also the jack info seems a little odd to me.
Please help im running out of idea
here what i see on the realtek manager
