Update: if anyone is experiencing problems with the addon (such as theres no alerts)
although I haven't had any problems yet, I know that combat logs can bug up.
To fix this, first
1. Make sure the addon is enabled, an english client, and see if /soundalerter will bring up options.
2. make sure you have your sound effects on and volume up
3. Try pasting in this:
/run local f = CreateFrame("frame",nil, UIParent); f:SetScript("OnUpdate", CombatLogClearEntries);
If that doesn't work, try pasting in /script CombatLogClearEntries()
