Hi Folks! I got me an optical S/PDIF cable, for connecting my rigs onboard Realtek ALC 888/1200 (suhould support dolby digital life and dts connect) my RX-V357 today,on Kiex´s suggestion (thanks for that, Dan ) The sound is much more defined and clear now, the midtone bass is also more swelling and powerful, and the general appearance of the sound is more rich. I only have two severe problems now: 1. The 5.1, and also my yamaha sub doesnt thats active but kinda was delivered with the receiver and has its own channel which seems to be connected to the 5.1 doesnt work anymore for standard audio content like MP3´s, Youtube, non dolby content and games... only stereo works there, and is also shown in windows and on the connected receiver 2. when i try to play dolby content, like a ripped DVD episode of Stargate for example, i get extremely chopped and distorted content. i know there are software based ways to solve this, or at least they are supposed to i appreciate any help on the topic, to solve this.... i would hate to go analog again, digital sounds simply so much better!
