Ok so I ran this on Linux Mint 20.1, VM source as of 2021/01/09. Works but little pops.
I get the same exact sound behavior on my Mac running Catalina, VM from 2020/11/09 that was prebuilt.
In both cases this image is Squeak 5.3 as shipped.
I'm not a piano player, but, what I vaguly remember as middle C does not seem to be middle C and the lower third of the keyboard seems silent though probably because the frequency is too low.
Starting from the left the third octave C is the first C I can hear. The D next to it I can hear, the E next I randomly hear or not. Hitting it quickly gives clicks. Hitting it and waiting is more sucessful but not 100%.
If this an analog system or an organ it would feel that some capacitor was not charging right or the air pressure was low.
