Hi,

I doubt that alsamixer provides a volume control for any class
compliant usb audio interface.

If jack runs on a "normal" configured system, then only jack has access
to the audio interface. IOW only jack clients can use the audio
interface.

If jack does not run on a "normal" configured system, all software
compiled to work with plain ALSA could use it, but only one app can use
the device at a time.

A system configured with dmix might be able to provide the audio
interface to more than just one app, but I'm not using it.

On my system firefox is build with

ac_add_options --enable-alsa
ac_add_options --enable-jack

alternatively I've got

https://github.com/i-rinat/apulse

installed. Since a while apulse doesn't work anymore, at least not for
me with Firefox. Assuming your distro or you compiled Firefox with
the mentioned options, then it still works with ALSA or jack.

At least Falkon, Pale Moon, Vivaldi, Opera and for audio and video the
best off all Google Chrome can be used with plain ALSA, too.

Regarding bluetooth I already provided the pointer to
https://linuxmusicians.com/viewtopic.php?f=18&t=19721#p103800 which
leads to
https://www.amazon.ca/gp/product/B01G3J1I5M/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 ,
probably something like this could be ordered somewhere else instead of
Amazon.
