Juason the port with the red glow is your spdif out. It is an optical signal which sends out a 5.1 sounds signal to hook up to a speaker system with an optical input. Anybody who has the sound issues it is basically electrical noise from ports. Best bet is to mute unused ****in the volume control such as mono in, aux in, and especially the mic if your not using it.
