Dear Sirs, I have vista 64bit [Asus P5W DH Delux Motherboard ATI Crossfire Ready Intel Quad CPU etc.]. Realtek Digital Output will not work for the 'test' I have no sound from speekers at all from cd audio or DVD etc. Volume Mixer - Device - Realtek Digital Output, does show a reading in green when music plays, but no sound. SOUND - PLAYBACK - SPEAKER (Realtek High Definition audio) 'Test'. Test is ok. But no green tick box? Below in Sound - Playback (as above) there is Realtek Digital Output (Realtek High Defintion audio) has a green ticked circle and a reading grenn bar when 'Test' is done but no sound. Speakers hardware are all ok. Trouble started when I downloaded Asus DH Remote software. I also do not know the 'Path' for this. Please can you help ?
