Very laggy sound when I stream sounds from Android phone to Ubuntu 23.04 via Bluetooth

[Ali Safapour]

I have used Ubuntu 22.04 for a long time and I decided to install Ubuntu 23.04. After installing, I paired my phone's Bluetooth (Samsung Galaxy A50) to my laptop and started to streaming my phone's sounds to be played by my laptop. I experienced very laggy sound, which was not the case in the 22.04 version. I had doubt that this problem may be related to my phone. So I created a live USB from 22.04, and I booted my computer from that USB. Then I clicked on Try Ubuntu and I paired my phone with live Ubuntu 22.04 and every thing worked fine. I did the same thing with Ubuntu 23.04 (booting Ubuntu from live USB and pairing with live OS) and the problem persisted even with a live fresh OS which nothing had been installed on it. So this Bluetooth issue is definitely is the 23.04 problem. Maybe you should increase the latency for Bluetooth buffer. I tried to fix this problem by installing pulseaudio, but no luck.
