Press the yellow button and choose an alternative audio channel. Move to another channel and then back again. Repeat as required.

Failing that do a manual rescan of the channel's transponder.

Failing that list which channels are affected so one can be a bit more specific with any advice available. :)

This is quite common on all E2 boxes not just on VU's.
