PC output to receiver issues.
Alright, I seem to have a strange issue here... I am running a 3.5mm to rca cable from my headphone jack in the back of my Gigabyte 990FXA-UD3 motherboard, going into the phono input of my Pioneer VSX-305 receiver, going to some pretty cheap Klipsch speakers. In order for my music to sound okay, I have to have my computer volume at two or lower in Windows, and anything up from that degrades quickly. My receiver doesn't have any digital inputs, only RCA. I don't think I need a DAC, the 3.5mm output is analog. So I am running analog to analog. Any ideas on how to change my setup so that I can use my Windows volume control? I am quite stumped as to why I get decent quality sound at 1 or 2 in Windows, so any ideas would be greatly appreciated.
The phono input is only for turntables. A Turntables output has lots of treble and very little bass, so the signal goes through a RIAA equalization filter then amplifies it, and sends the signal on to the normal part of the pre-amp. More than you needed to know, but Any other Input including tape monitor will work. ( not Rec Out ).
