Bluetooth apt-x music lag, stutter

RenoYeh — Tue, 03 May 2016 22:08:59 GMT

Hello,

I've updated my Z4T LTE to latest version 32.1.A.1.185 (Android 6.0). Now while I play music through bluetooth to apt-x supported deviced (system has detected apt-x supported) the music often stutters if I use resource-intense apps like google+ facebook chrome etc. The situation does not appear in a short period after reboot. Perhaps it's about resource previledge of different apps? Does anyone know if there's an option to solve this problem? Thanks.

Reno

@RenoYeh

Could you test it while on >>> safe mode

Do you experience the same issue @Viridis

Not on my Bluetooth audio device, but mine does not support apt-x.

Hello sorry it's been a while. I have crawled this thread entirely: /t5/Xperia-Z5-Z5-Compact-Z5-Premium/Bluetooth-audio-stutter-after-marshmallow-update/td-p/1103796/page/35 and I think it's basically the same problem.

I have tried in safe mode playing music with the only built-in music app through aptX to my bluetooth speaker, initially there are absoultly no problem (because it has few apps/services running, of course...) until I intentionaly open dozens of memory-consuming tabs in chrome and run as many apps as I can at the same time, the stutter does occur in safe mode only less frequently than normal mode. I'm no engineer so I'm not capable of reading system logs in any means, so I can only guess that it has something to do with system resourse consumption or with the processing priority of BT audio.

Some people in the thread above says it is a problem about the firmware/hardware of the FM/BT chip and sony has tested to shut down the radio feature to get BT audio works fine, well if that is true than I am willing to give up the FM radio feature, because the HiFi bluetooth audio of Z4T is one of the main reasons I bought it!
