Hello, I'm hoping someone can help me. I had an HP Pavilion that had Realtek ALC888S chipset on-board. This worked GREAT as I could plug my sub-woofer into the lime green "line out" jack on the back of the pc and get sound from all 5.1 speakers when sitting in front of my monitor. The spkrs I have are an old Altec Lansing model where the ctr+frL+frR+rL+rR all plug into the back of the sub. In addition, I was able to plug in a digital coaxial cable from the orange "line out" to my HT receiver and get 5.1 when playing BD/HD or DVD on the RPTV. Unfortunately, I had to return the HP due to Vista 64-bit software compatibility issues. So now here's my problem....The computer I now have has Vista 32-bit and on-board Realtek ALC888 (no S). When I plug my subwoofer cable into the lime green "speakers" jack I only get L+R sound from my PC spkrs when I test them in the Realtek HD Audio Manager. I have d/l'd the latest drivers (v1.99 was the latest I found) and I'm still not able to get the audio working the same as on the HP. It's rather annoying! I admit that I haven't even tried to connect the HT receiver as the mobo only has an optical SPDIF "out"...no coax. But I do have an optical digital "in" on my HT rcvr...I just don't have the cable Would any happen to know if this will work for the HT? Any info / solutions regarding connecting the 5.1 and HT would be greatly appreciated....Thanks. BTW - I can't even tell if the source of this problem is hardware, software or driver related!
