media volume cuts out



Hi, I have a droid x. My media volume keeps going out and I don't know why. Call volume ring volume etc are all fine but no sound for music, soundboards, apps etc. The only way I've found to fix this is to reboot the phone. I have a ford truck and my phone automatically links with it when I get in. I don't think it has anything to do with it but I thought it worth mentioning. Is there anyway I can fix this problem?

Note: I don't belive this is related to the low volume problem others seem to be experiencing. I installed audio manager widget and my media volume bar as well as all others are at max but still no media sound at all. I've also checked to see if the mute thingy on the unlock screen is checked and its not. Any help would be great. Thanks in advance!
