Question

Connect AMP for surround but sub is now gone...

I have a connect amp and a playbar. I had a powered sub plugged into the amp and everything was great. I decided to add 2 bookshelf speakers to the amp as well for surround. I hooked it all up and did the surround setup in my browser. Now I only show one Sonos component and have no more signal going to the sub. The surround is working though. 

I'm about ready to toss this whole system and got back to a wired setup. The sound is great but it's been a pain in the ass. If anybody can tell me how to my sub back I'd sure appreciate it.

    I guess you should notify us that just because the Amp has a sub and left/right speakers, you can't use both. I have set it up as another "room" and now it works, just not in surround mode. But I love how you can sync all of the rooms for a whole house music experience. This also allows me to play the rear speakers and turn down the volume of the playbar as to not blast out the whole house at night.

    Hi Howie, looks like you found your answer already. When bonded as a surround speaker, the subwoofer output on the new Amp is disabled as well. This is because the unit is only getting sent the audio for the rear left and right channels, not for the subwoofer or .1 channel.

    You can have it as a separate room and group it, as you mentioned in your post already, but it's not the same sort of experience.

    It may not be a good option for you since you have the Playbar already, but if you were using a second Amp, one could be your main home theater device, receiving the audio over HDMI from the TV. That one would be handling the front right and front left, along with having the active subwoofer output. In that configuration, the front stereo speakers would be creating a simulated center channel, since you wouldn't have a dedicated center speaker.

    I am in exactly the same place, I have bought a beam which is excellent, I want to add rear speakers and a powered sub (I have both from my old setup) but if I buy a connect amp either old model or new for my surround neither will support my subwoofer. Could this possibly be fixed with a future firmware update.
