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

I had three boards die on me before. The usb-to-serial chip suddenly got very hot, maybe because of some unlucky connection I made, and then it remained dead.

Can you make a pull request on Github?

Maybe, it might be possible to allocate or deallocate BT memory once, I'm not sure. You'll have to test it.

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...

Or use a specialized IC like this one: http://www.ti.com/product/ina226

Here is something with SPIFFS using the internal flash, only playback of PCMs though: https://github.com/MrBuddyCasino/ESP32_Soundboard

Suddenly I want to know these things as well, even though I have absolutely no use for this information. I just love drama.

Nice! I suppose this will be commercially available?

The error: 'struct avrc_ct_conn_stat_param' has no member named 'feat_mask' should be fixed. Did you pull? Maybe try a "make clean" first. Also I think it would be better to move this discussion to a Github.
