I have gone through the whole gamut of trials with setting up playing audio through bluetooth and have not been able to make it work reliably (i.e., got it to work one time, and has not worked after rebooting).
I can see the bluetooth interface (hciconfig) and can see the speaker (D100 creative) in a hcinconfig scan, but run into problems with bluez. The documentation is terrible and has not changed much since this guy wrote about it. I really do not want to talk about or debug this issue further. I am beaten and worn out on this issue.
However, I seem to have better luck connecting to the D100 using the default ubuntu gui. I can get the sound to work through the bluetooth speakers and I get sound when I click on the "test sound" button. How can I do this same thing using command line? Where can I find out what the bluetooth/sound app uses in the backend to make this work and play an mp3/wav file?
