Iḿ using zorin now for a few weeks and super happy. It runs really smooth.
In the beginning I had some issues with bluetooth sound what was sounding a it underwater but was able to solve this. A while ago it started again and since today my bluetooth is switching on and off every second. Power saving is not causing the issue.
I tried to reset/restart bluetooth in the terminal but not solved the issue.
What else can I try more?
I´m using Zorin core 18
Restarting may not really get a full restart. Selecting the BT connection, then "Forget" and connecting it fresh will give a full restart of it.
Thanks for your support.
This is not even possible. See attached screen recording.
That video makes me wonder about the bluetooth adapter or WiFi Radio adapter itself.
Are any errors logging? While watching it flicker on and off, open a terminal to one side and run:
journalctl -f
If you can Identify the card:
lsusb -nnk
in case this is a firmware issue.
Yep, there it is.
You can see that it is timing out and resetting.
This means that the software, audio, bluetooth etc are not the issue.
The kernel is requesting the hardware, and it is crashing, over and over.
This looks like a kernel regression for realtek, to me.
Can you check your installed kernels (You have had zorin only a few weeks, so I am not sure if you have had it installed long enough for a kernel update):
dpkg --list | grep linux-image
If you have more than one installed...
Reboot and enter the grub menu - if you are not dual booting and do not normally see the Grub menu at boot - reboot and tap the esc key furiously, or tap tab if esc is not working.
It should then show grub - Where you can choose to boot Zorin OS or
Advanced Options for Zorin
Select Advanced Options and in the next menu, arrow key down to the earlier kernel (Not the one that says recovery) to highlight (select) it, then proceed to boot.
Then test bluetooth on that kernel.

Oh you have plenty to choose from.
Any from the -20 to -29 are worth trying.

I only have 35 and 29 to choose from in the overview. Both having the issue.
could you show me the output of
sudo grep -E "submenu '|menuentry '" /boot/grub/grub.cfg | cut -d"'" -f2
Then, You could install an older one from the Repo's or go the other Way and install a newer one (for that, You would have to add a Repo or PPA dedending what Kernel You want use). Are You interested to test one Option?
Advanced options for Zorin OS
Zorin OS, with Linux 6.17.0-35-generic
Zorin OS, with Linux 6.17.0-35-generic (recovery mode)
Zorin OS, with Linux 6.17.0-29-generic
Zorin OS, with Linux 6.17.0-29-generic (recovery mode)
Windows Boot Manager (on /dev/sda1)
UEFI Firmware Settings
yes please
Okay, we could start with installing a newer Kernel. That could bring better Support.
But to say one Thing to that: Secure Boot must be diabled. With enabled Secure Boot, the Kernel will not work. So, maybe duble-check Your BIOS if it is really disabled.
To install a newer Kernel, there would be 2 Options (well, a bit more but let's take these 2):
- Using the Mainline Tool
- Using the Liquorix Kernel
The good Point about the first Option is that You can use for the actual Installation of the Kernel a graphical Interface for the Case You prefer that.
The Liquorix Kernel Installation would run in the Terminal but when You get Kernel Updates for it, that comes through the normal Software Updater. I personally use the Liquorix Kernel, too. Not because I actually needed it. It was only out of Curiosity.
For using the Mainline Tool:
Open the Terminal and type
sudo add-apt-repository ppa:cappelikan/ppa
and press Enter and type in Your Password. After it is added type
sudo apt update && sudo apt install mainline
When installed, look for the Mainline Tool and open it. There look for a newer Kernel and install it.
For using the Liquorix Kernel:
There You have 2 Options to add it. The first Option would be to use this Command:
curl -s 'https://liquorix.net/install-liquorix.sh' | sudo bash
This will check what System You have and add the fitting Repo. Or You can add directly the PPA for Ubuntu with
sudo add-apt-repository ppa:damentz/liquorix
When added, type
sudo apt update && sudo apt install linux-headers-liqourix-amd64 linux-image-liquorix-amd64
When installed, reboot and on the GRUB Menu choose ''Advanced Options'' and there choose the Option with the Liquorix Kernel to boot with it.

Will give it a try soon. First Iḿ going to try a simple USB BT dongle to see what happens with that one.

Issue solved.|
I´ve killed my internal bluetooth adapter and added a rule to prevent the adapter to start again after a reboot.
Then I´ve plugged in a 3 euro 5.3 BT dongle and that one is working like a charm.
Decent and normal sound, finally.
Anyway, thanks for support and insights!

When that solves it for You, I will mark Your post as Solution. Could You maybe add what Bluetooth Dongle exactly You bought? I mean Brand and Model. That could help others who search for one, too.
