• Download and install the player plugin "ASIO Output" from: www.foobar2000.org/components/view/foo_out_asio. The "ASIO Output" plugin is necessary for High Resolution Audio playback.
• Download and install the decoder plugin "Super Audio CD Decoder (DSD)" from: https://sourceforge.net/projects/sacddecoder/files/foo_input_sacd/. The "foo_input_sacd" plugin is required for decoding and playing DSD Audio files in foobar2000.
