I have a gateway and 3 portals. 2 of the portals work fine. I get no sound from the 3rd one. It is hooked to a receiver. External sources to the receiver are the shaw portal and an LG Blu Ray player. The sound from the blu ray is fine as is the sound from the FM & AM sources on the receiver. The only source from which I don't get sound is the shaw portal. Any ideas as to what the problem might be? I'm not sure if I can re-boot the gateway/portals without any consequences, so I've not tried that yet.
