Audio constantly cutting out
Problem Description
When I play audio it is extremely choppy. I have tried playing from an iphone and from windows with the same results.
The setup and wiring works and sounds correct when playing directly from an SD card (ESP32-audioI2S library.)
Is there anything that I can try to improve the Bluetooth connection? Is there a specific esp32 board version that is recommended?
Device Description

Provide your Version of the EP32 Arduino Core (or the IDF Version)
Espressif 32 (6.2.0)
I have checked existing issues, discussions and online documentation

Isn't this just a duplicate of this issue ?
The only thing that you could try is to play around with the A2DP_I2S_MAX_WRITE_SIZE is config.h How would you be using IDF 6.2.0 when the latest version is only 5.3 ?
You could also try to use the Arduino API of I2S instead my AudioTools to rule out that the issue is in my I2SStream.
I didn't seem like an exact duplicate. I have the exact same issue playing from IOS, a windows computer, and Android. My audio output was also choppier.
How would you be using IDF 6.2.0 when the latest version is only 5.3 ?
I misunderstood, I am using platform-espressif32 version 6.2.0 which corresponds to ESP-IDF - v5.0.1 & Arduino - v2.0.8

Same issue.
Changing the data pin to 19 solved the issue! It now plays perfectly :) For reference I had the same issue with both the MAX98357A and the PCM5102, different speakers, and different power supplies so I believe the issue was with my esp32.
