Volume control problems when using bluetooth aptX

[milm81]

Hi,

I tried pairing my new Xperia Z3 compact to a Loewe Speaker2Go bluetooth speaker and even though I can get the phone to send music to the speaker I cannot control the volume from the phone. Also the default volume the phone is set to is very high. Has anyone else experienced bluetooth sound volume control problems?

Many Thanks,

Milos

Thanks, but this "throw" option doesn't enable the volume control on the NYNE Bass Sport Speaker.  My Galaxy S3's volume control works, My MacBook Air & Pro's volume control works,  My Asus UltraBook's (Win 10) volume control works.  I know being a Sony device the Xperia has a darn good reason to disable the volume control (higher fidelity?, AptX?), but I'd like to know why and if it can be enabled.
