Skype Version 7.36 (507), OSX Mavericks on 2011 iMac
Skype's sound effects are insanely loud. They play at the volume of the overall Mac, which is up full and should be. But everything else on the computer is an appropriate volume (system sounds, browser, etc.), Skype is just way WAY too loud.
This is only its chat and related sound effects, NOT calls. Has nothing whatsoever to do with voice calls.
Skype does have its own volume control, but it also does absolutely nothing, both for the sound effects AND calls. Has no effect whatsoever.
Is there any way to quiet just Skype down?
EDIT: Another observation in case it's somehow relevant - changing Skype's audio devices in preferences also does nothing. All sound effects (non-call related) always come out the internal speaker regardless of what device I select.
