Had this amp for a while but didn't use it much. I recently bought a new 55" screen and decided to use my home theater Amp/speakers with it. The problem I'm having is with the analogue inputs. I'm using the analogue 5.1 for my desk top PC. I use the sound card and connect it to the amp using phono cables. When I first connected everything it was working fine. I assigned the analogue multi channel to the pc. But today all of a sudden the sound won't work at all anymore. Everything is still connected the same way I checked the pc side and sound seems to be ok, no errors or windows problems. If the sound card wasn't working that would show up in windows. Sound is going through but for some reason the amp just won't give me any sound. I've checks the amp settings and they are fine. I feel like I must be missing something but can't figure it out. If anyone has the same amp and had similar issues please let me know! Thanks.
