No Audio from Podcasts or Music after Using ATVFiles

I have 3.4.3 of ATVFlash installed on AppleTV 2.3.

I find that sometimes after using ATVFiles to play avi files, that subsequently when I play any iTunes music file or podcast, that no audio is output. All other system sounds (eg. menu navigation) works fine.

The music/podcasts indicate that they are playing, but I simply hear nothing.

The only solution I have found to date is to reinstall ATVFlash using the USB flash drive.

Is this a known problem, and are there any fixes available?
