Hello, I build an app with buildozer on ubuntu and installed it on my android using Android studio. App loaded, screens worked, but sound did not. So, I tried to fix it by converting it from mp3 to wav and then used
ffmpeg -i "orig_thrmlpu2.wav" -f wav -acodec pcm_s16le -ar 22050 -ac 1 "ffmpeg_thrmlpu2.wav"
