Bose Companion 5 not working with latest Mac OS (Ventura)

I just wanted to resurface a solution to this problem that another member posted some time ago, and which is in a closed thread. The original message read:


"There are many threads over the Internet discussing issues with Bose Companion 5 when connected via USB. I found no answer in those discussions, but I found a solution and I'd like to share it here. All the old threads are locked, so I can't post a reply, so here we are. Chances are you exactly know what I'm talking about if you found this page in your search engine results ;-)


What was happening: My Companion 5 frequently stopped working after a little while of having the music paused, or when I switched audio outputs (think listening music via speakers, then making a call via headphones, then wanting to switch back to loud music via speakers - the second time no sound went out until I disconnected and reconnected the USB cable).


I am running a 16" Macbook Pro with all the latest updates. The issue occurred when the speaker was connected using a USB-C to USB-A dongle and then USB-A to USB-B cable.


All my issues disappeared when I used USB-C to USB-B cable without any dongles."


I wanted to let all know that using a USB-C to USB-B cable (without dongles) indeed resolved this issue for good. I had sent Bose my subwoofer unit for repair, but the issue persisted. But using the previously mentioned cable solved all issue immediately. Posting here in case it is helpful to anyone.

I'm having the same problem here w/ my Bose Companion 5 speakers connected to an Apple Studio Display and my MBP M2 Max running Ventura 13.2.1 I'm using a USB-C to USB-B cable (as suggested above) which works when first plugged in but then stops working after a few minutes. Disconnecting the cable and plugging it back into the thunderbolt port temporarily restores sound. The problem can also be replicated by manually switching the output (in System Settings/Sound) to the Studio Display speakers (which works) and then back to the Bose USB Audio setting (which then fails). Worth noting: The system does not have to go to sleep for the speakers to stop working. Toggling the output in Sound also can cause them to fail.


I'm wondering if anyone else is having this same problem and if they have stumbled upon a solution?
