Warbled Sound On STV CH103 only, VM
 

This morning around 4am while the STV Nightshift programme was on there appeared to be warbled sound from CH103 only, tried re-booting the STB but that didn't help, been reported to VM, but curious if anyone else has noticed this not just this morning but on any other occasion?

Perhaps there was a problem with STV, but as of now the sound is back to normal.
