               HD Audio SPDIF        : out 2X44.1-192kHz, 32bit
Playback Device from Control Panel : ..from advance tab..Max avialable bit and sample rate is 24bit@192kHz all

Audio File : wav format both 16bit@44.1kHz and 24bit@96kHZ
Audio Player : Foobar 2000 with WASAPI

               From system above, I could play all audio file I have

               With XXHighEnd, I could play all 16bit@44.1 file with #3 engine .. but couldnt for 24bit@96kHz file

               I tried to activate DAC test then. and for

              this may mean that i cant play my 24bit@96kHz file with this sound card.

              I tried to test again with DAC test share mode ... and I set  bit and sample rate at 24bit@192kHz in playback device Exclusive Mode (with 16bit@44.1kHz file)
