[pulseaudio-discuss] Issues with HSP profile on Bluetooth Headset

[Jerome Leclanche]

Yeah, I have phonesim running on 127.0.0.1:9696 and
/etc/ofono/phonesim.conf configured to look at that, but no dice. I'll
look at it more, I'm not sure how to confirm pulse is talking to ofono
properly.

Aside that, it seems to me like it would make sense to split the
"HSP/HFP" into two distinct HSP and HFP profiles. It's been pretty
confusing and as it stands, if pulse cannot support both HSP and HFP
at the same time, it should more clearly communicate that and why.
I'd like to help any way I can, but I'm not a C dev by any means so a
non-trivial patch is out of my reach.
