Losing Notification Sound

[NickA]

Sometimes when receiving a text message, the screen comes on momentarily, but I don't get a notification sound. It will keep doing this until I make an adjustment in the volume (either up/down), then I start to get the notification sound again.

Anyone else experience this? I have an HD7.

Nope... Weird. The worst I get is my notification sound, but it skips a bit.
