Schiit Decrapifier released - USB power isolator

[spaceace1014]

The iPhone can probably electrically see the Bifrost just fine but the Bifrost probably has its own machine language.  
 
Say you were calling someone to order a pizza Your Iphone is you and the italian guy in the dirty little pizza parlor is your Bifrost. This guy who is fresh from italy(your Bifrost) gets your call and you say hello and he thinks maybe your his cheese supplier and he starts gibbering at you in italian and you try to stop him but he doesn't understand a word your saying so finally you hang up (that's an error). Your Wyrd or a direct cable are analogous to the phone. The phone made a perfect call but you weren't able to order a pizza because your phone and your Bifrost speak different languages which in computer terms is called a driver.
 
I can confirm that the Wyrd in general will work with an iPhone and if you can confirm that the actual Wryd you've got on hand is actually functioning in a simple scenario by connecting your Bifrost through it to your computer than the problem most likely lies not with the iPhone and not with the Wryd and if that's the case the most likely culprit is the Bifrost.

In other words I suspect the problem is with the lighting to usb adapter.

A single cable or 2 cables? I use a CCK and a standard USB.

 

[Jimmy101]

Computer works fine with Wyrd.

 

[Jimmy101]

What gen iPhone are you using?

 

[spaceace1014]

Can you connect the lightning to USB adapter to anything at all like a keyboard or a digital camera?

CCK and standard 2.0 usb

What gen iPhone are you using?

If that was to me, I said in post #490 an iPhone 6+.
 
I know there was a recent security update, not advertised. I can test both USB ver 1 and USB ver 2.

Much appreciated

OK, tried one sequence that seems to work. Connect phone to Wyrd, power on Wyrd. Phone is recognized immediately. Then power on BF. All is well. Makes no sense to me but I am electronically illiterate

 

[Jimmy101]

Scratch that. Worked 4 times in a row. Now nothing

I keep all my DACs running all the time. The Wyrd, I do power on and off, but it is on second. Then I plug in the phone and go.
There have been many iOS updates since the last time I tried this, so perhaps something went wrong there. But it usually works if not on the first plug-in, at least the second.
 
Will try of course once I get home...

...and until I got home, I forgot that I have all three generations of USB.
 
USB ver 1 - plugged iPhone directly into the DAC. I heard an audible pop through my headphones. I hit play on the iPhone and there was no sound through ether the headphones or iPhone. Through the Wyrd, it was identical. It took an unplug and replug to get the pop sound from the DAC. But then there was still no sound. Both lights on the Wyrd were on, indicating I had a connection, but there was no sound. And I next plugged directly into my laptop (did not unplug anything but the CCK) and there was sound through the same chain of USB cables and Wyrd.
 
USB ver 2 - plugged iPhone directly into DAC, and it reported too much power draw. Plugged iPhone through Wyrd into DAC. I heard the normal click sounds as I started to scroll through my music. And once I hit play, there was sound through the headphones.
 
USB ver 3 - identical to above. When I plugged my iPhone directly into DAC, it reported too much power draw. Plugged in through the Wyrd, and there was sound.

Forgive my ignorance but am I correct in assuming that by different gens you are referring to the lightning USB adapter or am I incorrect?

No, there are different generations of the USB card inside the Schiit DACs.
 
The first two Schiit DACs I purchased both came with USB gen 2. I purchased a Bifrost in February and a Gungnir in August of last year. These both came with USB gen 2. I purchased a Yggdrasil, and this is the only DAC from Schiit that comes with USB gen 3. I sold my Bifrost (Uber upgraded to Multibit) and recently purchased an original Bifrost (4399 upgraded to 4490 - sorry, I'm a bit of a collector) and it came with the older USB gen 1.
 
That's why I asked the question - which generation of USB card do you have in your Schiit DAC? Unless you see the too much power issue when plugged directly into the DAC, my guess is you have USB gen 1. I heard it click, but I never got sound to come through the DAC.
