I have a bit of an odd situation, and wanted to ask for ideas.
Recently started connecting a JBL Charge 2+ to my MBA 11 inch, mid-2013, via Bluetooth. I noticed that there's clear delay between sound event and sound being audible via the JBL.
The problems persists across applications (so for example, playing video via VLC means the sound isn't synced, same for youtube videos in different browsers, same for mp3s that start playing with a small delay, etc.)
The delay is minor, but noticeable, in the range of 0.5s I'd say.
At first I thought it might be a Bluetooth driver issues, but now I found out the following: just connected another JBL device, a Flip 3 to the same MBA, and the sound plays without noticeable delay. I'm not sure if they use the exact same drivers, but now I'm wondering:
Is there a chance that it's a hardware problem? Didn't really consider this a possibility, but now I'm not sure anymore.
How to test, and, ideally, fix this issue? How can I isolate the reason for the audio lag with the Charge 2+?
Any help would be appreciated!
