I have Harmon Kardon AVR 25 ii receivers and I have attached it to Bose 701 front speakers and three other Bose surround speakers and an subwoofer. All the speakers work except for right speaker, I need help.

anything that works well is always worth investigating for a repair
it could be a simple fuse for that side amplifier, loose , broken speaker wire
have it checked out and then decide if it is worth repairing

On my yamaha 375 receiver if I connect digital or hdmi it disables the balance/bass treble etc but they work with anolog don't know if yours might be the same just abit strang if anolog doing it aswell

Bose is a pain in the back like Apple. Everything they make is proprietary or it won\'t work. The 901 series is one of them.

If you need further help, I’m available over the phone at https://www.6ya.com/expert/ernie_b93ee48ba0eab50b

check to make sure you dont have a bad hdmi cable thats what it sounds like is stereo balance set to the middle on the receiver.

That would depend mostly on your subwoofer. There are some that slave off the front left and right speaker outputs and still pass the amp's power to the Front Speakers. That would be the only way that would ensure volume control.

Otherwise you have to feed a self-powered sub from the Tape Outs but that won't allow volume control from the H-K.

We have this same problem We had friend visiting; he pushed a button and we've lost sound but only on the dvd. I've tried every setting I can think of, but can't get sound. Did you find a solution?

What other functions work and are any of them multichannel digital sources?

Has it EVER worked? NO? Set it up right.

If you have the harmon kardon receiver, check out this reasonably priced system. You can actually find it cheaper than at this website but I have these speakers and, when paired with the Klipsch sub-woofer, it makes movie watching an unbelievable experience.
