changing loudness with amixer

Question

I want to set the loudness with amixer on my Ubuntu 20.04 system, Kernel 5.15. amixer prints the the "Simple mixer control 'PCM', 0" and "Simple mixer control 'IEC958', 0". But no master. When I set the loudness for PCM it does not change the actual loudness at all.
