Hi,

I am running the A2DP sink example on CYBT-343026-EVAL board. I play a 48kHz (sample rate) test audio file from a Pixel 4A android device.

The oscilloscope show the I2S word select signal to always be at 44.1kHz. I enabled android developer options, and sure enough this is the only sample rate that is selectable (i.e. not grayed out).

It seems that the 48kHz cannot be negotiated.

Any suggestion on how to make the 48kHz available? I would expect this to work after reading KBA228409 and this page https://community.cypress.com/t5/Resource-Library/A2DP-Sink-Example-on-CYW20706/ta-p/246388.

Thanks, Davide
