Dell posts NV beta driver to resolve DPC audio interrupt

Today Dell posted the 196.86 NV Beta driver. This driver implements the change which ManuelG of NVIDIA Forums spoke of here:

The fix does not disable Powermizer. The driver was in a DPC state for too long and this was corrected. It should not have an adverse affect on performance. Tomorrow (Tuesday) we will be releasing a new driver which unfortunately does not include this fix as it did not make it in time (the fix was added shortly after this driver was built). The fix will be in drivers following this. Once I get the exact driver versions, I will update this thread. Quote Source
