I have set up sound to a jabra halo bluetooth headset and it works using
"mplayer -ao alsa:device=bluetooth soundfile". This works fine for apps
like mplayer which can specify the right output device.
However, I want to use espeak (in a console) to play back text files -
its a good method to check grammar - but I cant get it working? It
works out of the box on a nokia n900, but I cant figure out how to get
gentoo (gnome desktop) to do it. espeak doesnt support specifying a
sound device that I can see - it uses portaudio which is supposed to
work with alsa bluetooth but how?
It looks like bluez is continually changing so most of the guides Ive
found dont apply - I am using bluez-4.39. alsamixer etc dont list the
bluetooth device and I cant see it in /proc/asound, but its obviously
there if mplayer can access it!
