I once worked around this issue by using BearSSL (see https://github.com/MrBuddyCasino/ESP32_Alexa/). You get ownership of the buffer, and thus don't have to copy. Its not trivial though, and I can't give any assistance. Another option to safe memory is to not use a threading model, but an event rea...

Look at the antenna feed points, the two bright spots on the black antenna part. In Pos 3 & 4, they are at the edge of the board, in all others they are in the middle of the PCB.
On a side note, is it possible to have the I2S driver send silence instead of the last buffer if it receives no data in time? I've yet to come across a situation where a buffer underrun doesn't result in annoying buzzes. Silence would definitely be the preferred output if there's no data. +1 for that
The problem is that Bluetooth consumes a lot of RAM, and the web radio needs a lot of it, especially for AAC. It is currently not possible to dynamically allocate and de-allocate the Bluetooth memory, which makes switching between the two modes during runtime impossible. You might get around this if...
