Bose USB Audio Speakers Do Not Reliably Work on Mac Studio "Audio MIDI Setup"
I own Bose speakers that connect via USB 2.x. I've had them for ten years.
They require setup via "Audio MIDI Setup."
Over the years, I have never had a problem on multiple Macs.
Last week I used "Audio MIDI Setup" to connect them to a new Mac Studio via one of the two USB-A ports in the back of the Mac Studio.
Problem: they do not stay connected, despite their status in "Audio MIDI Setup," which shows that they remain selected as the device for sound output, etc. (See image.)
The only way I can get them to play sound again is to restart the Mac. After restart, they work for a while, but suddenly go silent, usually after I have "paused" the sound with the spacebar.
I could find no useful guidance in the Support materials for "Audio MIDI Setup."
Yes, I checked the cable connections several times. They're fine.
