With about a month of v2.5 in the 568.2, I think I have found an issue:-

Scenario 1 - CD in tray (598DP via Smartlink) and play disc. Source can be either CD or DVD (only difference being preset default). Counter shows disc is playing but no sound. Flick between different sources and back to CD or DVD an still no sound. Only way to get sound is to put the system into std-by and then try again. Always cures but the problem is intermittent.

Scenario 2 - Put DVD in and play movie. OSD show Movie 6 and all other expected info, however, zero sound from centre channel. L/R and surrounds are working though. As with previous issue, the only way to resolve is via std-by.

Neither of these issues occurs all the time, but, it is a recurring issue.
I'll be dropping a line to M, but, have any of you 568-ers experienced the same or similar ?

Cheers

Nick

PS...when it's playing properly, I think it is still better than ever.
