I have the following bluetooth adapter:
UGREEN CM591 Bluetooth Adapter 5.3 using Actions Semi ATS2851 chipset.
By default, the system used the 5.15.0-100-generic kernel and the Bluetooth manager did not run on it.
I updated the kernel to version 6.5.0-25-generic and after that the bluetooth manager started working.
Having launched the SVEN AP-B900MV headphones in detection mode, I found them and connected them, but the problem is that the sound still does not come through them - all sounds are played through the monitor speakers by default. Headphones are also not visible in the audio devices menu.
In general, this UGREEN adapter works very strangely. The headphones may connect and then disconnect after a few seconds. They can work for a few minutes and then switch off. I searched the Internet for information on this adapter and realized that in general, many people have problems with it in different Linux distributions.
I also have a NuPhy Air75 keyboard, but I couldn’t connect it with this adapter - for now I’m using it via wire. But this is a topic for another discussion.
Also, for your information, I have Windows 11 and Linux Mint installed in dual boot. Secure boot is disabled.
After studying the forum a little, I tried to run the following commands, but there was no result:
