I have pureaudio installed and ASIO4ALL and have them configured properly. Pureaudio (2.2a) is enabled and set to use ASIO4ALL. In the music tabs I have BASS player selected and ASIO4ALL selected in the ASIO section. I have chosen my Nvidia HDMI audio as my sound output device. Every time I try and play any music in MePo I get zero sound. I have AC3Filter installed for all of my movie based DTS and AC3 passthru and I even tried AC3File too but still no sound. I have no problem playing any of my content in FooBar2000 via ASIO over my HDMI connection to my receiver which receives the streams in multichannel PCM format.
