<div dir="ltr">bluez-utils package (in <a href="http://www.bluez.org">www.bluez.org</a>) has a2dpsink element that handles sending audio to a bluetooth headset using a2dp, might be worth trying it. It is capable of sending sbc audio (bluez-utils has a sbc encoder) and mp3. <div class="gmail_quote">On Thu, Aug 14, 2008 at 11:49 PM, axel lin <<a href="mailto:axel.lin@gmail.com">axel.lin@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> hi list, I want to playback a Theora video file and output the audio to my bluetooth headphone.
