hopin you guys can help me out with an issue as of late: ill be playing NES via XRGB and after having it on pause for a while or booting up another game later or something, no sound. i fiddle with the cords and that did it once i think, but not this last time. so, i go boot up say SNES over RGB...same issue: graphics look fine, no sound.
my setup is said upscaler plugged into the TV over HDMI, with a digital optical out both going back to the receiver. because of this, i can turn up the volume on the TV and hear the sound coming through just fine - also, anything else plugged into the receiver's great too...leading me to believe the digital optical cable might be the problem. and before it's asked: i did this setup to maximize the HDMI's on the set & receiver, figured there's nothing on the retro systems that woudln't be carried over digital optical just fine rather than figuring out another way.
just wanted to throw this all out there to see if there's anything i might be missing, i don't wanna just conveniently assume the cheapest component is the problem (think it was the lowest priced cable on monoprice, natch), ill double check the receivers settings on that channel but there's nothing about them that should cause it to randomly mute just taht one channel sometimes.
