it's probably a driver problem, because by changing the 01 to 00 in the registry, it fix the problem on my computer. I hope that they will release new audio driver soon for you.
the new d810, d610 and d410 are very well designed and made with good quality materials like magnesium. the i6000, i9200,9300 and xps2 are a little bit less solid, but much better than the 8600 or 600m.
