Dacmagic USB ticking/popping noise when switching tracks on Foobar - Help

[K_19]

Hey all,
 
I'm wondering if anyone can help me work out this annoying little glitch I have with the Dacmagic that I got recently for my bedroom rig.
 
It seems that when using the usb input of the Dacmagic through my Macbook Air/Bootcamp Win 7, I randomly get this pop/tick noise when I switch tracks or stop and switch to a different song.
 
Several factors to consider:
 
- The pop occurs right before the next song starts, with random loudness/direction (sometimes it pops hard enough for me to be concerned, other times not that loud; sometimes it pops in the left side of the headphones, sometimes the right). It never pops in any other parts of the song, which tells me something's going on between transition of one song to another.
 
- The popping does not occur all the time. Sometimes that switching of tracks is smooth, but perhaps 1/3 times it's not.
 
- The pop occurs regardless of filter used with the EXCEPTION of Directsound (this I'm assuming because the transition from track to track is completely smooth in DS mode). ASIO, KS, WASAPI all gives the random popping noise when I switch tracks.
 
- There seems to be no correlation between the popping and change of sampling rates or bitrates of songs. Sometimes it pops from mp3 320 to mp3 320k, FLAC to FLAC, etc. It's one of the first things I checked and it seems completely random.
 
- I don't think it's anything inherently wrong with the USB port of my laptop; my Stello DA100 USB for example is completely smooth and glitch free.
 
- I also tested it through my other Windows 7 desktop which is more powerful, and Dacmagic USB still has the same issues. The system doesn't seem like a culprit here at all.
 
 
So with many of these things seemingly random, I'm quite baffled on figuring out what the problem is. Perhaps just the fault of the DAC chip?  If anyone has any clue about what may be going on here in this popping glitch happening it would be great if you can help me troubleshoot this little issue. Oh, and yes, the coax input of this Dacmagic is completely glitch free (tested it with my hiface) and I may invest in another usb to spdif converter down the road anyway, but till then I'd like to have the USB component work properly.
 
Thanks in advance!

Anyone? I'm sure I'm not the only one using the USB out of Dacmagic to Win 7/Foobar here... any problems on your end?

Hi K
 
What output buffer length are you using?
 
Suggest you try 2000ms, if not already set at or more than that.

The buffering is set at 1000ms and I've tried various other higher rates with which didn't change a thing

  The ticking still remained...

Hi K
 
I suggest you try 2000ms and also with Full File Buffering set to 2000000kb.

In my case the opposite works: using J River/WASAPI a longer buffer creates all kind of problems. I use 50 ms (hardware buffer).
 
A simple test is to run DPC Latency Checker, check if the system is high on latency

The reason you get a pop is because the audio feed is terminated instead of there being digital silence between songs if I remember correctly. Unsure of how to fix, would recommend using S/PDIF inputs with the DACmagic anyway.

That would certainly explain why there are no ticking in the DS, as the transition is smooth...
 
Is there any way to apply this action to WASAPI and KS filters? I suppose applying it as a DSP would break the bitperfect-ness though, in which case I may as well use DS anyway...
