Geek Pulse: Geek desktop DAC/AMP by Light Harmonics
Aug 18, 2015 at 7:47 AM Post #8,941 of 13,800
  I'm having an infuriating time this morning trying to get my Pulse X Infinity working with my new laptop. I seem to be in an infinite loop of installing driver, disconnecting and reconnecting the Pulse, powering on/off the laptop and the Pulse, switching USB ports etc etc.  Occasionally I've managed to get the device recognised by Windows, and yet it doesn't appear in the Windows playback devices dialogue box. I had some trouble with it on my previous laptop now & again, but nothing like this.  Out of all the USB DACs I've used, I have never had any issues that come anywhere near the flakiness of this one when trying to get it recognised properly in Windows. For those who've been requesting my updated thoughts on the Pulse X Infinity v DiDiT DAC212, for now I rest my case.

 
 
Had problems with it also...finally i concluded maybe its the motherboard and I bought a USB 3.1 card. Until now no hiccups.

Had my Infinity running for a bit on an upgraded Win 7 Ult x64; and, from a clean installed machine.
 
Don't like the sound IMO. Reverted to Win 7 (maybe it was the drivers?). 
 
But its working (after a timer i disinstalled it).
 
Compared also Win 8.1 and Win 10. They sound the same.

Ok after much futzing this morning, I've identified the culprit as the LH 1G usb cable that I was using from the LPS to the Pulse

. Annoyingly, it wasn't manifesting as a consistent failure - the laptop was able to see the DAC (most of the time), but not actually get it to stream any sound.  I was also seeing intermittant weird things like this error message in the LH control panel (note also the greyed out master volume control).
 

 
Replacing that cable with a generic Lindy one seems to be doing the job, as is bypassing the LPS usb cleaning altogether. I hope the 2G cable when it arrives (maybe, one day) is more reliable.

It has been for me but I have also had trouble once with it. I had let my GF use my computer speakers with foobar and I forgot to change it back to using the USB output. Once I did, all was better. Funny enough, I had to replace a component and forgot to plug its audio cable in so I was frustrated last night figuring it out and realized my mistake. So so far, settings/things being plugged in properly were more of my issue than the unit not cooperating.

Aha! Good to know you've found the culprit! There should be a warranty of some sort on those cables. Stick to cheap USB cable in the meantime! And Enjoy!!!

OK, I remembered I have done this also at the beginning: 
 
PC USB connected to LPS thru USB Source -> USB from LPS -> to Pulse.
 
Gave me also connection issues.
 
BUT USB straight to -> Pulse. NO.
 
Using 2G cable (split) however does not.

@coletrain104 Here are some free additional DSD128, DSD256 (as well DSD64 and DXD) stereo and multichannel tracks you can use.

Hi, there

DSD256 will be Native DSD first on Windows Platform. And after, we will implement Our PureDSD on Mac platform as well…

So, remember when they had those sample songs in various formats, including DSD? does anyone know where to find that now? With all the site changes it is hard to keep track of where everything went. Many don't even have their unit yet, so it would be strange to think they got rid of the samples.

anyone have examples of such sources?

Or for a more interesting experiment now that the Pulse will support DSD256 in the near future:

Or for the list of their entire music catalog:

Do the Pulses come with a card describing the proper sequence to use to connect, power on, plug in headphones, and play music without risking blowing your phones? Can someone post that info here? Do I also recall that you aren't supposed to leave any headphones plugged into the pulse when not in use?
While I seriously doubt I will get my stuff by the end of August as promised in the new shipping schedule, I don't want to destroy my headphones when I get the Xfi.

Maybe I'm just crazy, but I leave my Infinity on at all times with my Audezes plugged in and the volume at -127.5dB (the lowest it goes). Have never had an issue of any type - no spikes, no sudden volume changes, etc. Seems like the new firmware is much more stable although as always YMMV. Also one of the many good things about the Audezes is that they can take a ton of power!
