Anyone know if this:

works well with Jackd? Can it run <5ms latency at 96 kHz with a good Bluetooth 3.0
adapter?

24bit/96kHz! Exactly what is needed to stream 16bit/44.1kHz mp3 via
bluetooth from mobile phones to the Hifi.
It could work as an audio device via linux' bluetooth stack (probably
involving pulseaudio at some point). But I don't think it will be capable
of <5ms latency given that you are using a shared medium as transport. And
I don't think you will need <5ms latency unless you want this to use your
Hifi as monitoring for your music-making (and don't have the spare cable).
Have fun,

I am assuming you have not yet bought this device. But if you have, the
first thing is to find out if there is an alsa driver for it. This page
seems to indicate that there is work in this direction but that it is not
complete:
http://bluetooth-alsa.sourceforge.net/
The fact that pulse has it's own BT IF would also indicate to me that
there is no stable ALSA implementation.
So while it may work ok in pulse... lowlatency would be a problem (a pulse
thing) it looks like not with ALSA (Jackd depends on ALSA unless there is
a bluetooth backend for jackd - none that I am aware of)
So it looks like Bluetooth audio is not an option for low latency work.
