Bluetooth not working properly

General Help
1

On my device I can't get bluetooth to work or rather, I can't get it to connect to my headset.

I've looked into various questions and "potential fixes" online already, they all kinda revolved around installing pulseaudio-module-bluetooth or the other bluez5 variant..

In the end, none of these worked. I always get the following error when attempting to connect to my device:
a2dp-sink profile connect failed for 74:45:CE:CC:03:BF: Protocol not available

I don't know enough about Zorin & Linux, or it's internal configuration, to properly assert which version of ubuntu I should refer to, or what kind of configuration the system is using for bluetooth to work.
Apparantly there are differences, either pulseaudio uses modules, or if using pulseaudio with pipewire... It's not clear to me, and some more documentation about this would make things easier.

I am using Zorin 16.

Kind regards,

Zorin 16 is based on Ubuntu 20.04.
See if this helps:

Also do you have blueman installed as that was one package you did not mention.

Can you also please post the output from terminal for:

sudo lshw -C network

Let's see what radio drivers you are using.

What do I need blueman for? My expectation is that bluetooth should work out-of-the-box in a Zorin installation, but I suppose that was a little high-hoped.

Also, I do not want to install Bluetooth drivers, not knowing if that is actually the problem. In the settings menu, I can turn Bluetooth on and off, and it can also detect devices properly. It only fails to connect to the devices that were set up, with the given failure message.
And looking at dmesg it does not look like a driver issue:

Here is the output:

Been there, same issue for a long time until I switched to Pipewire

I don't see that working for me.

When going through the step sudo apt install pipewire-audio-client-libraries I get:

$ sudo apt install pipewire-audio-client-libraries

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

When trying to install pipewire-alsa I get:

Do you want to continue? [Y/n]

I just want my Bluetooth to work and not uninstall distribution packages in the process.
It does seem that zorin-os version 16 depends heavily on pulseaudio.

Zorin OS uses Systemd and systemd is heavily integrated - including pulseaudio.
You might try adding the following options to your /etc/modprobe.d/iwlwifi.conf file:

options iwlwifi 11n_disable=1 swcrypto=1 bt_coex_active=0

sudo nano /etc/modprobe.d/iwlwifi.conf

I see.. I've read that Ubuntu 22.04 comes with pipewire, so once Zorin 17 comes out, I'll be on that anyways. So a temporary fix for a few months would be fine.

Can you tell me what those options do?

disables the 802.11n wireless standard

enables software-based encryption (swcrypto) for the Wi-Fi adapter (in order to avoid hardware enabled encryption).

deactivates Bluetooth coexistence mode. Bluetooth and Wi-Fi operate on similar frequency bands, and in some cases, their signals can interfere with each other.

What version of Zorin16 do you have installed? I've just confirmed and I have both pipewire-audio-client-libraries and pipewire-alsa packages installed. Running Z16 Core here. Zorin-os-desktop package still running, never been asked through the process to uninstall it.
