This is one of those problems where things seem to be fixed, but then suddenly aren't again, and no solution seems apparent.
I was flipping between bitstreaming DSD to my Geek Out 450, and taking it to PCM so I could use various plugins. (At this time, I was in WASAPI mode.) I finally decided to go back to bitstreaming...except, when I tried to play DSD tracks, I would get a very loud stream of white noise (loud enough that I had to make a grab for my volume control to prevent damage to my speakers, with the music itself playing faintly in the background.) Any attempts to get it to play properly failed.
I went online, and found a thread at LH Labs about how to configure the Geek Out in JRiver. They said, basically, to use the Light Harmonic [ASIO] driver in MC, make sure "DSD bitstream in DoP format" is checked in driver settings, select Bitstreaming->Custom in settings and checking only DSD, and then making sure output encoding is set to "none" in DSP Studio. I did all those things, and DSD started playing properly again.
But...I had no volume control slider available. After trying various things to get it working to no effect, I switched back to the "LH Labs Geek Out [WASAPI]" driver. To my non-surprise, the white noise on bitstreaming came back. Fine, I decided, I'll go back to ASIO mode and forget about the volume control. However, when I replicated the steps above to switch back to the ASIO driver, made sure "DSD bitstream in DoP format" was selected, and went back to bitstreaming, this time I was still getting the white noise. I tried everything I could think of to reset it: unplugged and replugged the Geek Out. Shut down MC and reopened it. Turned off the computer and turned it back on. Even uninstalled and reinstalled the Geek Out's device driver. All to no avail...when I try to bitstream DSD, no matter what the settings or whatever I try to do, I still get a loud wave of white noise with the music playing faintly in the background.
To add insult to injury, I'm able to get DSD playing just fine through the Geek Out using Foobar2000, which suggests to me it's something in the interface between MC and the Geek Out, as opposed to the DAC itself, that's causing the problem. But I can't figure out how to fix it. It almost feels like something's "stuck" in the MC settings, and changing the settings on-screen isn't fixing it.
If anyone has any idea how to get this running again, I'd greatly appreciate it. Right now, I could care less about plug-ins or anything like that -- I'd just like to get MC to play audio to the Geek Out in direct mode, DSD included.
