Generically, isn't this what's shown in the PA Volume Control,
Configuration tab, in the profile pulldown for the USB audio device?
I have 3 devices. Most options in the profile pulldowns say
"(unavailable)" . I've never explored why.
I only seen "unavailable" for one device - a set of Bluetooth noise
canceling headphones (Sony WH-CH700N) which shows High Fidelity
Playback (A2DP Sink), Headset Head Unit (HSP) (unavailable), Handsfree
Head Unit (HFP), and Off. I believe the unavailability is due to some
combination of the driver for the USB BT dongle (with it's own
problems, being a cheap Chinese knockoff) and the BT sound drivers. I
assume the "unavailable" is for modes that the driver thinks the device
(or maybe just the type or class of device) should handle, but doesn't.
