Are you talking about the list movement and action sounds? If so:
SOUNDS & MUSIC
Enable Audio - Checked
The appropriate sounds are in the boxes?
If you press "play" and hear nothing then:
GUI > LAYOUT
Use Sounds from Layout - Unchecked
and
GUI > OPTIONS > DISPLAY DELAY
Either uncheck Enable Display Delay
or check GUI Sounds
I had a problem where long sounds would play but short (~1s) wouldnt. Turns out the delay was longer than the short sounds.
Any help?
