I am not a (Linux) programmer :(, I'll try the list.
A little bit of progress:
I have managed to compile "2years old" "nohands" software, tweaking
"libhfp" Makefile with CPPFLAGS = -f permissive and
"tests" Makefile with LDFLAGS = -lpthreads
After doing (suggested by software) hciconfig hci0 scomtu 64:8 (as root),
application (and daemon) hfconsole started, I could search my phone (SE
X8, Android one), and connect.
Even place / answer calls, but ONLY on headset audio.
When I tried to switch to "speaker" I got total system FREEZE. (repeatable).
I am now guessing if it is related to BT or Alsa audio... (no Pulse
support in this soft, Alsa and OSS only).
And audio (at least output) looks working good on this machine - I can
play music /movies.
Would a test with external USB "sound card" give some relevant information?
