Neither method barely seems to be working for me. I got as far as to be able to select DDL or DTS in my Panel; but still I wasn't able to play some sound due to the PUMA issue. The sys-method never worked for me, at all. A version of this for original Realtek drivers R2.73 would be much appreciated as I don't know where to get original R2.71 anymore. Found some on softpedia, but for EVGA - caused problems on my system.
