PingSounds is an addon that enables sounds for the ingame ping system while disabling all other sound effects. It is not possible with default wow settings to have sound effects for only pings enabled while disabling all other sound effects. When enabled the Addon will mute all sound effects except the ones that are playing when ingame pings happen.
You can enable and disable the addon with /pingsounds enable
and /pingsounds disable
You can also use /pingsounds
to toggle the addon on and off
Due to technical limitations the ping sounds will only start playing after a short delay of about 20-40 seconds after login
