Hello Friends,
i have the following problem after yesterday I made a full update/upgrade on both different systems
pc & laptop the following problem appear.
─$ uname -r
5.14.0-kali2-amd64
While i am trying to connect to any Bluetooth device the status show connected and second after that disconnected but it does not connect at all because i don`t hear confirmation sound from the device...
I have got 3 different devices and the situation is the same for all of them:
[bluetooth]# devices
Device 74:45:CE:4A:8E:B6 WH-CH510
Device F8:5C:7D:2F:04:CB JBL Charge 5
Device 04:FE:A1:24:57:87 JBL Flip 4

At the Bluetooth devices Gui when try to connect at the down side of window appears error:
" Connection Failed: No audio endpoints registered "
I have tried:
-to delete the devices then add them again no success via gui - no success
-to delete devices via bluetoothctl --> trust --> pair --> connect - no success
[bluetooth]# pair 74:45:CE:4A:8E:B6
Attempting to pair with 74:45:CE:4A:8E:B6

[bluetooth]# trust 74:45:CE:4A:8E:B6

-to /etc/init.d/bluetooth restart --> which was working perfecly before update , but not anymore - no
success
-connect the devices to another windows 10 pc connect instantly and stay connected
-connect the devices to another GSM connect instantly and stay connected so i`m 100% sure that its not
by any chance external devices fault
Update:
/etc/init.d/bluetooth restart && pulseaudio --start --> Now the device is succesfully connected but the sound device isn`t avaible into pavucontrol at all
meaning that the sound is playing via the laptop speakers ....



Thanks in advance, i think this will be helpfull solution if we get to it of course
for a lot of people where this problem will happen...

I bolded and underlined(for emphasis only) what your real issue is. WHY are you using Kali for anything like this?? Read the Kali links in my posting signature, and their own website. They say, specifically, to only use Kali for pentesting/security, and even then they recommend not installing it but using it on a virtual machine. Things like wifi and bluetooth are disabled or otherwise modified intentionally on Kali. Again, that is because it's for security/pentesting purposes, not for playing music/videos or daily use.

There are some things you can do/try, but they aren't going to address your (likely) ongoing issues with using Kali in this manner:

Hello,
thanks for your reply
We had completely another hosts for work, entartaiment virtualization backup solutions server etc.
and so on those with Kali i used those are also pentesting our facility and
and to learn something new and interesting, and just because i like the idea of linux and its freedom.
They are installed from 1 year and never had a single issue until this update thats why i`m so curios about.
But i had such problems and with another distributions already.
We don`t rely on that machines in any matter.
Thank for your time and effort

So if you have other machines for entertainment and work, why are you using Kali for this??? Again, Kali's own website tells you to NOT use it for the purposes you're using it for. Further, the update could have removed a kernel module that made that device work. Since you say nothing about your hardware, we can't tell you that...the best place for Kali questions would be the Kali forums.

Again: your real solution is to not use Kali.

Hello to update the topic,
because we don`t just give up
problem was solved with purge pulseaudio && bluez* and reinstall
to the both kali machines + one mint.
Greets thanks for you time

Congratulations; you reinstalled those things, which was the last thing said on the link you were given. Good luck with the numerous other problems you're going to have using Kali like this, and ignoring the advice you've been given, not only by folks here but the people who WROTE Kali.
