I'm using a USB Bluetooth adapter for my computer to connect to my wireless headset (Mpow Jaws) (https://www.amazon.com/Mpow-Bluetooth-Headphones-Wireless-Cancelling/dp/B01MDK0PIP?th=1). The USB Bluetooth adapter seems fine and can detect Jaws presence, but when I try to pair the two, the request is automatically denied. Pair Attempt I checked all of the usual Bluetooth related issues (Trying to pair when something is already paired (Although this headset does support multi-pair), power cycling the headset and trying again) I do believe that something is fishy with the OS because I got an unusual flag on the Bluetooth dash: Weird Flag I obviously pressed the Fix it button, but it came back the next time I opened the Bluetooth console. That and how fast it rejects the pair attempt. There is literally no time I can detect that it is legitimately trying to pair the headset, it auto rejects faster than a progress circle can appear.

EDIT 0: I upgraded from 17.04, and the Bluetooth Adapter/Headset pair worked fine.

EDIT 1: I also deleted the configuration from the Bluetooth console and re-scanned and attempted the pair again. It was able to detect the Headset, but no luck on the pair.

EDIT 3: It could be possible the the Bluetooth USB driver is out of date from the upgrade (And maybe something broke, but not so badly to cause failure in any noticeable way, aside from failure to connect devices), but I'm not sure what to do in such a case.

EDIT 4: This is the Bluetooth adapter: (https://www.amazon.com/gp/product/B01BQO3QZO/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) it is a Costech 10/11m model.

EDIT 5: I just noticed that the entire sound driver system is missing. There appear to be no sound drivers.Sound Drivers This is bizarre because I have integrated speakers on my HP laptop and have USB speakers plugged in via, 3mm port.

EDIT 6: The sound works on a Kubuntu Live System USB stick of the same version number. I strongly believe that this is a sound issue rather than a bluetooth issue. The Bluetooth adapter is responsive and able to detect my Headset, however I think it breaks when it tries to integrate with the sound system and that's where the issue is arising from.

Edit 7: Upon executing sudo apt-get remove --purge alsa-base pulseaudio & sudo apt-get install alsa-base pulseaudio sound is restored, but there is no KDE sound icon in the system tray. Additionally, the volume up/down keys have no effect. Some packages from kubuntu-desktop are removed in the process. I though that by reinstalling them I could get the sound button back in the system tray, but the lack of audio issue comes back as well... Additionally sound devices play and are discoverable in the system settings/audio region.

These are the packages that are removed:

The following package was automatically installed and is no longer required: pavucontrol-qt-l10n Use 'sudo apt autoremove' to remove it. The following packages will be REMOVED: alsa-base* kubuntu-desktop* pavucontrol-qt* plasma-pa* pulseaudio* pulseaudio-module-bluetooth* pulseaudio-module-gconf* 0 upgraded, 0 newly installed, 7 to remove and 4 not upgraded.

try to install kmix

sudo apt install kmix
reboot

you'll have the sound manager back.

However for the bluetooth I have the same issue: Lost bluetooth functionality after upgrading from 17.04 to 17.10

EDIT: Solution found (check out link above)

I think your issue is caused by the recent bug and could be resolved by commenting the last 3 lines in /etc/pulse/default.pa:

###.ifexists module-switch-on-connect.so 
###load-module module-switch-on-connect 
###.endif 

To get KDE sound icon in the system tray and volume up/down keys working you need to install plasma-pa:

sudo apt install plasma-pa
