Sub not switching off...

[pmanson]

Hi All,

Recently did a few upgrades on the cinema (started with just the TV and then seemed to snowball).

Anyway the sub is not switching off/to standby when the amp switches off (it used to switch off automatically after a couple of minutes with the previous amp).

The new amp is an Onkyo 656 (old one was an Onkyo 626). The only real difference I have in settings is that I have the AMP set to ARC to allow TV apps to pass through sound to the amp.

Would this stop the sub going into standby? Or do I need to try a new sub cable?

Many thanks,
Phill

Interesting!

We seem to be getting a lot of 'hum' from it which I suspect is interference.

HDMI pass through is switched on (oh well i'll just make sure I remember to switch it off after a film from now on

Thanks both
