When connecting my new August EP650 bluetooth-headset, it pairs but I don't hear anything

With Pulse-Audio's configurations open you can watch a new item showing up immediately after pairing. On the left it is labelled "EP650" and there is a drop-down box named "HiFi-Stereo-A2DP-snk-profile" (I translated it from German)


$ sdptool search --bdaddr local a2snk
Failed to connect to SDP server on FF:FF:FF:00:00:00: No such file or directory


$ sdptool search --bdaddr local a2src
Failed to connect to SDP server on FF:FF:FF:00:00:00: No such file or directory

After reading some threads, I realized, that there is no: /etc/bluetooth/audio.conf

I am able to do some Linux-stuff you tell me, but I do not know what is wrong and do not know, how to get that file?

Does it come with any application?

Thanks for any helpful advise.

The audio.conf file is not needed. There is a bug in either Bluez or Pulseaudio causing issues if you want to use A2DP

A current work around is to

wget https://gist.github.com/pylover/d68be364adac5f946887b85e6ed6e7ae/archive/d698974910bbb7d016ec0ad08c1bf41b4b524364.zip
mv ~/d68be364adac5f946887b85e6ed6e7ae-d698974910bbb7d016ec0ad08c1bf41b4b524364/a2dp.py .a2dp.py

Then after connecting to the headset run ./a2dp.py in terminal and enter the number for your headset and let the python script do the rest

  • $ sudo ./a2dp.py Connection MADE Selecting device: Device MAC: 00:12:D0:02:F7:EB Command: pacmd list-sinks failed with status: 1 stderr: Home directory not accessible: Keine Berechtigung - Translation: No authorization/permission Es läuft kein PulseAudio-Dienst oder nicht als Sessiondienst. - Translation: There is no Pulse-Audio-Service running, at least not as a Session-service.

  • Have you installed updates since installing as there was an issue with connecting to headsets crashing pulseaudio that was fixed sudo apt-get update && sudo apt-get upgrade

  • @longman There is no reason to use sudo for this command

  • This works flawlessly. Don't forget to change the permissions to allow the file to be executed as program.

    confirming this works on 17.10 with sony WH1000mx2 how does this still not work out of the box.. Mar 20, 2018 at 10:48

Simply apply your required changes on /etc/bluetooth/main.conf instead of /etc/bluetooth/audio.conf as this file has been removed in new versions.

and for solve Failed to connect to SDP server on FF:FF:FF:00:00:00 see below link and make some changes on dbus-org.bluez.service to use features of blueZ-4 as sdptool in blueZ-5 not work properly.



Get the index of your card:

pacmd list-cards

Set the cards profile to a2dp (example: index 2):

pacmd set-card-profile 2 a2dp_sink
