Thanks!

Working perfectly on Kubuntu 19.04. Thank you!

Took me nearly a whole day to get a sound out of this little beast :) ...

Thanks!

Two comments:

1.) If python3 is used as system default, the fix-bt.py needs a little modification for the gobject import:
from gi.repository import GObject as gobject

2.) If pulseaudio is run in user mode, the systemd service - of course - needs to be run as the corresponding user:

[Service]
# ...
User=foo

@tobiasweede, Thanks in advance.

Thanks a lot! This worked like a charm.

u saved my day. Thanks!

Thanks for the script. Unfortunately I am getting the following failure:

I am trying to get bluetooth audio to work on a Beagle Bone Green that is Debian 9.9. I am using a Broadcom Corp. BCM20702A0 Bluetooth 4.0 USB dongle. I am fairly new to working with bluetooth audio on linux. Any suggestions or help would be greatly appreciated. In the meantime will continue to research the failure.

Thanks!

@pylover @Mihara I suppose we can auto-detect device mac addresses so the script is more flexible and user-friendly.
Not sure if this is reliable enough, but it's working for me. Please, review and feel free to add to fix-bt.py around line 38

# Attempt to auto-detect previously paired bluetooth devices

        if not device_path:
            continue
        device = ifaces.get(device_path)

        if (
            bool(device.get('Paired'))
            and str(device.get('Icon', '')).startswith('audio')
            and device.get('Address')
        ):
            DEV_IDS.append(str(device['Address']))

Thanks. It stereo works now for me

Worked like a charm on ubuntu 19.10! Thanks! 👍

Dude!!! this thing worked like a charm on my Ubuntu 18.04....had been trying to listen to audio using my headphones for a week but had no success until this. Thank You! :)

Thanks @pylover your python script is working fine on my Ubuntu 18.04 LTS Laptop I was facing problem with my Mivi Roam Bluetooth speaker. It seems Ubuntu update for 18.04 LTS has bug as I am start getting problem after applying updates.
I have done small tweak in your script shebang, in your python script shebang has this line: #! /usr/bin/env python3.5 whereas I am using python 3.6 and same is mentioned in my shell envoirnment so I have changed the shebang line in your script to #! /usr/bin/env python3.6 which worked fine for me and fixed the Bluetooth issue in my system. Thanks once again :)

Worked well with Elementary OS.

This is on a freshly installed Linux Mint 20.1

Hmm on my machine a2dp was not available (in the pulse audio volume tool it was listed, but listed as "not available"

I found a post that helped me:

sudo dpkg-reconfigure bluez
sudo dpkg-reconfigure linux-sound-base

The Installation script is ready for those who can't copy and set the executable flag of a file in Linux. So just do:

curl "https://gist.githubusercontent.com/pylover/d68be364adac5f946887b85e6ed6e7ae/raw/install.sh" | sh

The issue with my Jabra Elite 75t was something like:

The headset would be connected in Bluetooth manager successfully, but the audio interface wouldn't appear. Turns out, the only supported by the device protocol is not immediately available in my debian 10 KDE. However, based on this reddit thread https://www.reddit.com/r/Jabra/comments/j5489d/if_you_use_jabra_earbuds_with_linux_you_need_to I've found that someone has made a package integrating this stuff - available in https://github.com/EHfive/pulseaudio-modules-bt. The package is deprecated as maintainer now switched to PipeWire (and it supports the codec), but I've built pulseaudio-modules-bt and installed it on my debian, and it still works perfectly.

Someone even made an installer here https://github.com/lagerimsi-ds/debian-buster_bluetooth_aptX-LDAC, but use it with caution.

I'm getting this failure:

Ignoring: Command: pacmd list-sink-inputs | grep "index:" failed with status: 1
stderr:

Running that command gives:

$ pacmd list-sink-inputs
0 sink input(s) available.

The headset is connected, ubuntu settings show the headset selected with a2dp sink, but the sound continues to come out of my speakers that are connected by traditional audio cable to my sound card.

Already tried in various version of kubuntu and always did the trick. Thank you for sharing!

Cara muito obrigado, resolvido aqui! Se eu tivesse dinheiro para te pagar pela solução eu te mandaria, mas só tenho gratidão para lhe dar. Muito obrigado!
