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)

but

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

and

$ 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

  • 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` – Jeremy31 Dec 26 '16 at 23:08
  • @longman There is no reason to use sudo for this command – Jeremy31 Mar 05 '17 at 11:16
  • This works flawlessly. Don't forget to change the permissions to allow the file to be executed as program. – Peeperkorn Mar 07 '17 at 16:12
  • any ideas on how to make the changes this script makes permanent? – Peeperkorn Mar 08 '17 at 09:25

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

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.
