Low volume through Bluetooth speaker

[Hildur13]

I have a Marshall Kilburn bluetooth speaker. Suddenly, the volume is really low when listening to music/radio through the phone, despite media volume set to max on the phone. Possibly the problem started with the last update (Android version 8.0.0), but not sure. I only know that sound output through this speaker was great and no longer is.  ClearAudio+ is activated (and was when it worked fine). 

Checked with a different mobile, and sound was as expected, so the problem isn't the Kilburn.

No one? Anyone?

Have you tried this? Seems to fix most recent Bluetooth issues...

Good luck!

Unfortunately, no success...

Few days later - working... Not sure what helped, unpairing/pairing a few times, restarted the phone etc. Now I just tried again without changing anything else and all of a sudden it worked. (Chose AVCRP 1.4)

Just kidding, not working again... Well, apparently connects, but not getting a full sound and proper volume. 🤔

Its quite late, hope you fixed the problem already haha ))

But I encoutered the same couple of months ago and I found the solution. (My Device: Galaxy S10 Plus)

All you have to do is to Activate Developer Mode and go to Developer Options.

When you scroll you will find "Disable Absolute Volume" option and you just need to turn it ON. 

Leave everything else default, it will fix the problem.

Hope this will help someone.

Good Luck!..

Thanks! It did start to work again and has been fine since then. Out of curiousity I checked the setting you mentioned, and it is ON (meaning Absolute Volume inactivated?). Not sure whether that is something I fiddled with or not. But it is working now anyway, even if I don't know why.
