I am wanting to stream to multiple bluetooth headsets at the same time using the a2dp profile. One headset works great but I can't seem to get a second one to work. It does not appear to be a purely pulseaudio problem as I can't get it to work using just alsa either but I thought someone here might be able to help. Any ideas? Using mplayer and alsa as a test If I specify one headset it works fine but when I then try to start something else playing on the other it fails with: [AO_ALSA] alsa-lib: audio/pcm_bluetooth.c:1614:(audioservice_expect) BT_OPEN failed : Invalid argument(22) [AO_ALSA] Unable to set hw-parameters: Invalid argument Any ideas on where to start? Thanks, Jess
