[Bluez-devel] Acer BT900 Headset profile

[Carsten Otto <carsten.otto@gmail.com>]

Hello!

I am quite unsure whether my USB adapter supports everything I need,
but with Class 1 and and higher number in the name (BT900) than I saw
elsewhere I don't think that is a problem.
I was able to setup everything, but can't manage to get more than
noise out of my headset. Whenevery I play sounds (or pipe something
into /dev/dsp1) the noise starts and stops just when the sound is
finished.
Please tell me where the problem could be.
Some information:
- The headset is a Logitech Mobile Bluetooth Headset
