Re: [Bluez-devel] can you use bluetooth alsa to let bt device use computer speakers as output?

I am confused, I Can't use plugz and have to use btsco???

I don't even see these binaries after installing btsco, like a2play

Legacy Stereo (A2DP) Testing
Only developers should need to use this testing code. The A2DP plugin
work is mature enough to use directly.

A2DP provides a way to send stereo high-quality audio to some of the
newer headsets. On all the headsets I've seen so far, this is one-way
audio, so if you were expecting to get something like a gaming headset
(talking to other players, getting stereo sound back from the game),
you should wait for the next generation of headsets to get 2-way A2DP.

This code is found only in the "btsco" package.

To test stereo audio without installing the alsa plugin, you can run:

	mpg123 --au - file.mp3 | ./a2play 00:0D:3C:30:32:AD

Where you replace file.mp3 with a good mp3 file and bdaddr with the
address of your headset. You can send live audio from line-in etc
using a command like:

	./a2play -s -d -r 44100 00:0D:3C:30:32:AD /dev/dsp

Don't be surprised to get a delay. It's probably under 500ms but not
much under that.

The A2DP sink code receives a stream from another device. Run it with:

        hciconfig hci0 class 0x200404
	sdptool add A2SNK
	./a2recv

It will try to bind to the bluetooth adapter and send audio out to /dev/dsp.
