I also from Hong Kong..
Just forgot the ASUS Xonar HDMA audio card or I must goes for it....
I bought the Creative Sound Blaster X-Fi Titanium Fatal1Ty last Friday (HK$ 1280.00).
99.9% play movie file from my PC, the sound is ok (SPDIF-->AMP direct)
However, some file just output garbage sound but not all files.
(e.g I have the 'Mariah Carrey concert' which format is BDrip 720p.X264 DTS-48000Hz 6ch Audio-CHD.MKV)
