Keep in mind that the alsa-bluetooth stuff has not has as much focus as
PA bluetooth stuff in recent years, but yes, this seems like a valid test.

As I said previously, I suspect it's simply due to the receiver built
into your machine not being supported by bluez as best it could.

Oh it's quite simple to setup, just pair the device and provide you're
using PA it just works.... the problem is that that it doesn't always
work well due to h/w support. This requires users to give feedback and
run tests such that upstream folks can make it better for everyone!
Please don't give up, just have patience and try and get involved :)
