Sound crashes since i19

Every RWZ MS raid I crash. Every Tin Mage, going into Director 11's room, I crash. I played with graphic settings to no avail, didn't change anything no matter how low I put the settings. It's not temperature, I've gauges on all my temps and everything is cool to the touch. However, I noticed that, on all the crashes, I always end up with a sound loop.

So on a hunch, I turned my sound down to 0 in the game and I've not crashed since. Did 4 MS raids in a row, max graphics, no crashes. I've played for 4 days now with no sound and not had a single issue.

My sound "card" is integrated into my ASUS mother board, so not something I conciously do anything with, Windows 7 x32 updates the drivers for me.

Does any of this chime with stuff you guys have seen that might be causing my issues:

Its not your sound card its the game , I also crash in the RWZ ship raids, in the Director 11 Warehouse and in the save the conference when you have to kill the groups inside before engaging the giant warwalker outside.

I have an Azuntech Forte 7.1 Xfi in one machine, at SB Audigy 4 in another and Soundmax integrated on my laptop and all 3 crash.

But with the sound set to 0, I don't crash. Ever. I've tested this for the last several days. Run 2 raids with no crashing. Exit the client, come back in, turn the sound up to 1 (any sound at all), go into a raid, crash. Bring the client up, sound to 0, no crashes anywhere.

I know it's the game, I don't have these issues anywhere else, I just want to know what I can change to make the crashing go away and let me still have sound, as it's tedious as heck to play in silence, and far less enjoyable.
