Guild Wars 2

For the last week or so, I seem to be loosing all game sound. First the sounds which accompany skills go, background music is still there; then a minute or so later all game sound is lost, all I get is a low hum.

All other applications like TS still work fine, I can talk to people and I can hear other talking, its just sound loss from GW2.

This happens to me occasionally too. Restarting my client seems to fix it.
