Amp dropping out intermittently

I have an Arc connected to my TV along with an associated Sub3. I also have 2 Amps that power 3 pars of of ceiling speakers (not setup as surround). Everyone now an then both Amps will drop out for a few seconds which is very annoying. I tried hardwiring (ethernet) one of the Amps to my router and it did not help.

Will it resolve my issue if I daisy chain the Arc and the two Amps together? Or do I need to connect the Arc to the router?  In either case, I need to run the the ethernet cable behind the wall which I’m not ready to do unless I know for sure that it will permanently resolve the issue.

I also want to mention that I have a PLay5 and pair of Play 1s so I cannot disable WiFi on the sytem

Hi @ustad2be 

No problem.

Grouping to play TV audio in other rooms can work, but it’s not officially supported. When synchronising music playback, the music can be pre-buffered and frames of it can be arranged to play at certain exact times - this is what Sonos is about. When playing TV audio, however, the main Home Theatre device (Arc, in your case) is unwilling to wait for buffering so that it can stay in sync with the picture on the TV. Surrounds and Subs are on a direct 5GHz link and can play without delay. When playing TV audio to other rooms, the network is involved which has a slower connection (Arc connects to the router over 2.4GHz) and extra devices (the router itself, and any other network devices on the path to the destination). Therefore, TV audio can played over the network, but it’s either going to suffer dropouts due to lack of buffering, or be delayed and therefore out of sync with the HT room if the buffer is increased. 

You can increase the size of the buffer by going to Settings » System » [room with Arc] » Group Audio Delay » Medium/High/Max. Experiment, and choose the lowest value that results in no dropouts. If you can’t hear the Arc in the other rooms, it should be acceptable. If you can hear the Arc, you may not find the result tolerable.

If you have the option of connecting the Arc to ethernet, that may also improve matters.

I hope this helps.
