Mac running 10.9.1. Driverless.
Have not tried on other computers. I suppose I could. I just know the problem goes away when I substitute in a Modi instead.
From a Windoze perpective: I'd check the drivers first. Many times if you change a property in the DAC specific driver for let's say an enhancement the sound cuts out, requiring an in and out of the USB cable to restore the flow of music. Perhaps the Bifrost driver is flaky and needs an uninstall/reinstall. do you have another DAC that you run on the same USB port? Can you try the SPDIF connection and see if the sound quits? Otherwise you might need to call for an RMA.
Edit: I missed the part about the MAC. Try the SPIDF connection, if possible.
Modi doesn't require a driver while Bifrost does.
Ugh. Now I have to pick up an adapter just to test all of this crap. Yeah, I'll try and do that.
Neither require drivers on a Mac.
Yep, I believe the MAC directly supports the USB 2 audio spec. and Windoze does not.
Now that I think about it, I didn't check the USB cable. Will swap that out too when I get home, but it doesn't make sense that it's that since the Modi did work with the cable.
Try another cable anyway. Nothing to lose at this point.
Dang, I didnt know the Bifrost required a windows driver... Mine hasnt come yet. Thats not good. Is it a generic driver or something we have to depend on Schiit to maintain?
Schiit has it to download from their site. It's a C Media driver.
Windoze doesn't support USB Audio 2.0 protocol natively (the one which makes modes higher than 24/96 possible).
If you have the equipment, try hooking up a DVD or CD player over coax or optical to see if the DAC works with the exception of the USB implementation. If it does, then you confirmed USB is the culprit. Try another computer is possible to determine if the DAC or computer is at fault.
I see in another thread that your DAC croaked last night. Was it the Modi?
Ugh, I wish. It was the Bifrost Uber. I describe the problem here.
So when are you getting a replacement? I understand their customer service is second to none. Whenever I asked questions via email the responses were amazingly swift.
