This has been bothering me a while but I noticed sometimes I don't hear my own sounds from my character (like WS or calls) especially if there is a lot of other sound effects going on at the same time (endgame stuff with an alliance or campaign/besieged)

In the ffxi config, you can change the amount of simulatenous sounds active.

If you add more does it make it more often I can hear my own calls/sounds effects or adding less only allows me to hear myself more so than others?

Played with it a bit but not noticing too much...
