[Bug]: minimodem fails to record audio

[nycki93]

Problem description

minimodem on termux does not request mic permissions and fails to record audio.

there is a workaround, following the same steps as in https://github.com/termux/termux-api/issues/450

in the file $PREFIX/etc/pulse/default.pa, add this line:

load-module module-sles-source

restart termux, and now minimodem will be able to receive audio from the microphone.

What steps will reproduce the bug?

install minimodem:

pkg install minimodem

try to receive some audio:

minimodem -q --rx 300

notice that there is no output, and Android does not notify you that an app is using the microphone.

What is the expected behavior?

Android should notify you that the mic is in use, just like it does with termux-microphone-record, and minimodem should begin to output bytes to the screen.
