Hello all, I just bought an A2DP headset (Jabra bt320s) and was trying to get it to play some music as per the instructions here (SBC DSPsink might be interesting...): http://www.guardiani.us/index.php/N800_custom_packages#Bluetooth_ALSA I followed all of the instructions, but no music and the headphones flash (indicating that they are not connected according to the instruction manual). I'm afraid Bluetooth is a bit of a black art to me so any help would be appreciated. The output of mplayer is: Nokia-N800-26:~# mplayer -ac ffmp3 -ao alsa:device=a2dpd2 /media/mmc2/Laura\ Gre ene-Moonlight,\ Music\ And\ You.mp3 MPlayer 1.0rc1-maemo.17.n800 (C) 2000-2006 MPlayer Team CPU: ARM [MENU] Can't open menu config file: /root/.mplayer/menu.conf Menu inited: /etc/mplayer/menu.conf Playing /media/mmc2/Laura Greene-Moonlight, Music And You.mp3.

Audio: no sound Video: no video It appears that the audio device isn't present. Is this because the headphones have not been 'captured' and a dev entry created for them? I started a2dpd before I switched the headphones on and expected it to have output something when I switched them on, but it just remains like this: Nokia-N800-26:/root$ a2dpd A2DPD[09:53:11.567]: init_ipc: Selected IPC: unix, addr=127.0.0.1, bcst=127.0.0.255, port=21453 A2DPD[09:53:11.568]: make_daemon_process: a2dpd [Jun 9 2007 00:16:35] starting ...
