Hi, I have MusicBeam on my archlinux and a few months ago everything was fine but when I started it today it just shows a grey window and the log shows an exception (same exception as below but no Errors before that).
I tried downgrading Java to 1.8.65 (jre8-openjdk-8.u65-1 and same jre and jre-headless) but afterwards I get the same behaviour and the following log output when starting the program:
==== JavaSound Minim Error ====
==== Unable to return a TargetDataLine: unsupported format - PCM_SIGNED 44100.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian
=== Minim Error ===
=== Minim.getLineIn: attempt failed, could not secure an AudioInput.
Exception in thread "Animation Thread" java.lang.NullPointerException
