Running 8.0.4. I've got a simple Volume Up macro:
Triggered by F19 (on a Mac USB extended keyboard)
Will execute Increase System Sound Volume.
It works, but it also makes an unwanted alert sound each time I push F19 (which gets louder as I increase the volume). I've turned off all Sound Effects in the Sound System Preference.
Oddly the Volume Down macro (with F18) works silently, as I want it to.
