Wel it might be. Depends a bit on what kind of material you want to play and what kind of audio device you have.- if I am using SPDIF pass thought to my receiver. Is useful to install this ASIO plugin?
Yep, ASIO4ALL is just an ASIO device driver and doesn't play anything by itself. The PureAudio plugin can use that driver.- if you install ASIO4ALL. Is still useful to install Pure Audio plugin?
