snd_play works fine here.
OK, I was hoping this wouldn't just be me

If I open the lastest version via SED.exe, version 8.10.1 then open a .c file and run it I get no sounds or music.
If I download the 8.03 and open previous version of SED.exe, version 7.36.1 then open the same .c file and run it I get sounds and music.
Downloading 8.10 version again still gives me no sounds

Latest sound drivers are installed
