Outer Limits 4x4 Board

Hi has anyone bought one of these and found it had an intermittant fault?

Apparently the jobbies from the first batch have a prob where the volume level reduces (by more than half), and you need to turn it off and back on again for the volume to go back up.

Has anyone experienced this??

thanks

no, but if it is doing it, surely it has warranty, send it back...?
