I recently picked up a Jabra BT620s headset for use with my Treo, and it
works great.  So I figured it would be nice if it worked with my
bluetooth capable Linux laptops as well.  Unfortunately, configuring it
to actually play audio on demand hasn't been as easy as I'd expected.

I followed the instructions at the bluetooth-alsa site, .a2dprc
attached, and .asoundrc looks like this:
	pcm.a2dpd {
	        type a2dpd
	}

hcitool scan shows my device address if its in associate mode, and I can
ping it with l2ping, but when I play audio after starting the a2dpd
daemon, I get a lot of debug output, some of which look like error
messages:

I'm running the a2dpd daemon as a normal user, as recommended...

Hopefully there's something simple I'm missing here... maybe one day
this stuff will come standard with Fedora installations and I won't have
to do any configuration.

Thanks,
Jesse

#
# Rate
# use 32000 if your headset seems to not support 44100 (HP/Logitech works well at 44100, Sonorix at 32000)
# However, 44100 is mandatory
# If using SCO, then 8000hz is the value needed.
# if the plugin do not give the 8000hz stream, then the conversion will be done by the daemon
# Until we use a real resample library, we won't get a good quality, this is prototype software.
#
rate=44100
#rate=32000

# buggy if I remember well
#channels=2

#
# plugin-rate default is the rate used between the plugin and the daemon
# if this value is not 0 then alsa will convert all stream to the specified rate and then send it to the daemon
# if this value is 0, then alsa will do no conversion at all, the daemon will do it's own resampling.
# This "features" is disabled because of the crappy quality of the daemon resampler
# For example, to test a2dpd resampling from 32000 to 44100 use plugin-rate=32000 and rate=44100
#plugin-rate=32000

# Allows to specify the sbc bitpool, this can help reducing bandwith
# 8 Allows to run on a 115200 bauds with corresponding quality ;)
