Xubuntu 23.04 bluetooth - br-connection-profile-unavailable

I have similar problem to: Bluetooth problem with Ubuntu 23.04 but there is no solution

I have bluetooth headphones Marshall Major III Bluetooth.

In Xubuntu 22.04 works perfectly, but after upgrade to xubuntu 23.04 no.

It is paired and after computer start it is conected and imediately disconected and few times connected and disconnected...

Bluetooth manager answers me: Connection is not succesfull:br-connection-profile-unavailable.

with this message I have found some answer in arch forum: https://bbs.archlinux.org/viewtopic.php?id=270465

so I have set "ControllerMode = bredr" in /etc/bluetooth/main.conf but it not helps (after comupter restart same behaviour) - and other adwice I do not understand :-(.

in dmseg output I have (I thing) found nothing helpful.

but something is in journalctl:

please could anybody give me any advice how to solve this.

Thank a lots

This worked for me:

service bluetooth start
systemctl status bluetooth
systemctl --user enable pulseaudio
systemctl --user start pulseaudio

For some reason this needs to be done to properly start the module.

thanks Babs! it partly works.

For me is enough run command:

systemctl --user start pulseaudio

and headphones stay connected after conecting

but I must run it after each computer restart... so I want do it automatically

after switching on command:

systemctl --user status pulseaudio

● pulseaudio.service - Sound Service

So I want run it automatically. I have created file ~/.local/share/systemd/user/sluchatkaBT.service

with content:

[Unit]
Description=startuje pulseaudio

[Service]
ExecStart=pulseaudio

[Install]
WantedBy=multi-user.target

but when after next restart computer:

systemctl --user status sluchatkaBT.service 

○ sluchatkaBT.service - startuje pulseaudio
     Loaded: loaded (/home/fik236/.local/share/systemd/user/sluchatkaBT.service; enabled; preset: enabled)
     Active: inactive (dead)

and

systemctl --user status pulseaudio

○ pulseaudio.service - Sound Service
     Loaded: loaded (/usr/lib/systemd/user/pulseaudio.service; enabled; preset: enabled)
     Active: inactive (dead)
TriggeredBy: ○ pulseaudio.socket

and headphones are again after conecting disconnected please colud anybody helps me what is wrong?
