Stereo Feed not playing properly on my computer

[shadow4256]

I live near the border with another county and like to both my county and the neighboring county sometimes. My county's feed works fine but the neighboring county's feed is a stereo feed(law enforcement on left,fire/ems on right). Whenever I try to listen to this feed I only ever hear the law enforcement (left)side and it only ever comes out of the left speaker. Does anyone know how I could get it so I can listen to both sides of the feed? I am using a HP pavilion dv9 laptop with windows 7. I play all feeds on my computer with win amp. I have tried using the web player and it hasn't helped either. If anyone can help me with this I would greatly appreciate it.
