I have my Advent transmitter plugged in to my Laptop headphone jack, but i'm only getting sound from one speaker. Both of them are tuned in to the transmitter signal(green light in on in both speakers). I disconnected the working speaker and connected the non-audible speaker by itself. still no audio is heard. I can turn on and tune the speaker til the green light glows, but still no audio. Is there anything else I can try to solve this problem. I've had the speakers for a while now, but haven't used them much in the past. Were working fine before I had stored them away
