01-20-11: LadavidI had the same problem. In my case, it turned out not to be an issue with Pure Music per se, but rather a mistake I had made in the configuration of the output sampling rate in Pure Music's Advance Audio Setup. I had set the output sampling rate and limit rate too high for the capabilities of my DAC, which is 96Khz maximum. I had set Pure Music for 192Khz. When I made the correction to 96Khz, I finally had sound.
thanks guys - I think you are right on this - haven't been able to get hiface to play with pure music. Have tried for hours but probably need to give it more effort.
Don't know if this is the same problem for you, but it's something to check...and something I mentioned in my first post.
I will admit getting things to work properly was a several day adventure for me that was unpleasant at best, so I can empathize with you.
