More and more distros are switching to Bluez 5, including Debian
testing. One of the major blockers for us w r t switching to Bluez 5
has been the lack of HFP/HSP support, i e, no recording from headsets.
However, support for this has recently started showing up on the PA
mailinglist. The support comes in two forms, both with oFono as
backend, and without external dependencies, like in Bluez 4.
The bluez 5 backend for HFP/HSP (ofono or native) will, as it looks
now, be switchable at compile time. I suspect we want the ofono
backend on Ubuntu Touch and native on the desktop (right?). We need
to deal with this somehow.
PulseAudio 6.0 release cycle has not yet started, as we should first
try to get the bluez 5 patches in. But hopefully we should start the
release process within two months and then there is a release 1-2
months from that. (No guarantees.)
ALSA 1.0.28 contains a few minor fixes and improvements, e g better
2.1 surround support, some support for cards with > 4 HDMI devices.
It's been out there for a few months.
So, what's the plan? I suggest we upload ALSA 1.0.28 in the
beginning of the 15.04 cycle, as early as feasible. There shouldn't
be anything stopping it, and some PA 6.0 stuff makes use of the
stuff in alsa-lib 1.0.28.
We could then wait for PulseAudio 6.0 to be relased, and after
uploading that, switch to Bluez 5.
But I just wanted to give you a heads up about what's going on in
the audio stack, and also gather your opinions/concerns in case you
want to do things differently?
I think that plan is sound.
It's true that the only blocker for BlueZ 5 was HSP/HFP support, and
migrating to BlueZ 5 has been long awaited. I'm all for finally going
through with this; but I agree it should wait until the start of 15.04
rather than trying to rush things in now.
