Why is my Bluetooth headset not working now?

Solution 1:

I had the same problem and for several months I have tried all possible solutions I could find to no avail,... until today!

I found the solution in post #17 in the following https://bbs.archlinux.org/viewtopic.php?pid=1526534#p1526534 (tnx SimFox3)

What I did:

First copy the files I edited

sudo cp /etc/bluetooth/audio.conf /etc/bluetooth/audio.conf_tmp
sudo cp /etc/pulse/default.pa /etc/pulse/default.pa_tmp
sudo cp /usr/bin/start-pulseaudio-x11 /usr/bin/start-pulseaudio-x11_tmp

Edit /etc/bluetooth/audio.conf

sudo nano /etc/bluetooth/audio.conf

This is in my audio.conf

# Configuration file for the audio service
# This section contains options which are not specific to any
# particular interface
[General]
Enable=Gateway,Source

# Switch to master role for incoming connections (defaults to true)
Master=true

# If we want to disable support for specific services
# Defaults to supporting all implemented services
#Disable=Gateway,Source,Socket
Disable=Socket

# SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA)
# Defaults to HCI
#SCORouting=HCI

# Automatically connect both A2DP and HFP/HSP profiles for incoming
# connections. Some headsets that support both profiles will only connect the
# other one automatically so the default setting of true is usually a good
# idea.
AutoConnect=true

# Headset interface specific options (i.e. options which affect how the audio
# service interacts with remote headset devices)
[Headset]

# Set to true to support HFP, false means only HSP is supported
# Defaults to true
HFP=true

# Maximum number of connected HSP/HFP devices per adapter. Defaults to 1
MaxConnected=2

# Set to true to enable use of fast connectable mode (faster page scanning)
# for HFP when incoming call starts. Default settings are restored after
# call is answered or rejected. Page scan interval is much shorter and page
# scan type changed to interlaced. Such allows faster connection initiated
# by a headset.
FastConnectable=true

# Just an example of potential config options for the other interfaces
#[A2DP]
#SBCSources=1
#MPEG12Sources=0

Edit /etc/pulse/default.pa

sudo nano /etc/pulse/default.pa

comment out (with an # at the beginning of the line) the following line #load-module module-bluetooth-discover

now edit /usr/bin/start-pulseaudio-x11

sudo nano /usr/bin/start-pulseaudio-x11

and after the lines

if [ x”$SESSION_MANAGER” != x ] ; then
        /usr/bin/pactl load-module module-x11-xsmp “display=$DISPLAY session_manager=$SESSION_MANAGER” > /dev/null
fi

add the following

/usr/bin/pactl load-module module-bluetooth-discover

Restarted and I was finally able tot switch to A2DP

Hope it works for you too.
