pnmixer 0.7.2-1 (riscv64 binary) in ubuntu focal

 PNMixer is a simple mixer application designed to run in your system tray.
 It integrates nicely into desktop environments that don't have a panel that
 supports applets and therefore can't run a mixer applet. In particular it's
 been used quite a lot with fbpanel and tint2, but should run fine in any
 system tray.
 .
 PNMixer is designed to work on systems that use ALSA for sound management.
 Any other sound driver like OSS or FFADO, or sound server like PulseAudio
 or Jack, are currently not supported (patches welcome).
