I did. I have an "Asus Zenfone Max Pro M1" (what a mouthful) and the volume is always too high and the audio ridiculously bad at "low" volumes. Changing some values with ALSA makes it almost bearable. The easiest way I found to do that was to root the phone, compile tinyalsa in termux and use this script to call tinyalsa with root:
If anyone has ideas how to do this without root, get around the issue of calls being lower volume or remove the dependency on tinyalsa and termux, I'm all ears.
