Hi,

I recently purchased a Motorola HT820 headset and DC800 audio gateway which acts as a a2dp audio source to the headphones or sink music from a mobile phone/computer to your hifi.
I can make the computer stream music to the HT820 headset without problems, but I can't seem to stream any music to my hifi from the computer via the DC800. When playing music to the DC800 the unit pairs with the computer and the LED on the front of the unit flashes as though the computer is connected to it, but no audio is heard from the speakers.

Below is the debug output from a2dpd. Is there any other information which may help solve the problem that I can provide?

a2dpd -g -f /etc/bluetooth/a2dp.conf

I can make the computer stream music to the HT820 headset without problems, but I can't seem to stream any music to my hifi from the computer via the DC800.

afaik, this is still only possible using "a2recv" in the old btsco project.

Is a2recv not for streaming audio from the DC800 to the PC? I'm trying to stream audio from the PC to the DC800. I can't seem to find any documentation on a2recv except the small snippet below from the bluetooth-alsa build page.

Quoted 6 lines

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.

I have installed the btsco package and tried running this and a2recv just hangs with no output. Is there something else I need to do before running a2recv?

I've also tried the command

mpg123 --au - file.mp3 | ./a2play bdaddr

where bdaddr is the address of the DC800, but this give no audio output either.

Any help would be very much appreciated.

Regards,
Stephan

Sorry for the miscue. You should go to the bluez wiki and use the instructions there for sending a2dp audio to a headset from your pc. It's best if you're on a recent bluez.

Hi,

Can anyone tell how to share internet connection in my computer to the other devices through bluetooth connection. Is there any software for this?? Please help me in this regard.

Thank You.
