Patch 1.4 (non beta) sound problem and corrupted audio drivers

[Mylloijya]

First, i had no problem with Skyrim 1.3 (except some bug related), but with 1.4 audio starts beeping for about a minute, and then game becomes soundless. When restarted Skyrim runs fine for a minute, then same thing again. After second try, i tried a console+qqq, and the game hanged. Had to reset computer, to find that audio drivers has become corrupted. My specs are: Core2Duo [email protected], Asus 5850, 4 Gb DDR2, Sound Blaster X-Fi Audio.

Also, Ancient Dragon instead of landing to the ground remains in the air (slightly off the ground), not responding for a 2 minutes, and then returns to normal.

I repeat, it happened with 1.4 patch, not 1.4 beta patch. Anybody else had this problem, and fix, if available, is appreciated.

P.S. Frame rate is much better with this patch.
