A2DP with I2C doesnt work

[mutedh]

Problem Description

Hello, i have one question, i use sigmadsp to control a dsp ADAU1701 with esp32-a1s but i think it doesnt work a2dp and i2c, . could be?

because when i use a2dp, the i2c doesnt send nothing.but if i dont use a2dp, the i2c send the information.

Device Description

AI-Thinker AudioKit, ADAU1701 from womdom
