Hi Paul,
I have tested the special version uniaud32-linux-3.2.102-MikeK.zip today.
The result is mixed.
After booting I got only distorted sound from the system sound and from pm123 (v. 142 Beta 1 from May 9, 2020).
After reboot and having the following lines in my startup.cmd enabled:
"unimix -id1 -cnt0 -val87"
"unimix -id1 -cnt1 -val87"
I got clear sound from system sound. Even volume control was working well.
Once I opened UniMixpm.exe the sound become distorted again.
unimixpm.exe is from 2005-08-12, size 218.282 Byte, found in C:\MMOS2\DLL\
Same behaviour after next reboot and starting pm123 instead of UniMixpm.exe.
Greetings from Potsdam/Germany
