I purchased my Yggdrasil 3 months ago. The first month it worked perfect. It has a great sound, I really enjoy listening to my music collection.
A weird problem started last month. The DAC kept randomly disconnecting from the computer. No noisy source LED, just one click as the relay switch went off. And once it went off the DAC never reconnected. I had to turn the Yggy off, disconnect it from power and wait 15–20 minutes before it could connect again. Sometimes it worked for a few days without disconnecting, some other times it took only an hour of listening to music before it went mute again. Extremely frustrating.
In the beginning I should point it out that previously I had used the same laptop and a Peachtree Decco2 for 5 years without a single connection issue. Anyways, I read Schiit's
DAC Problems web page and followed all the Windows 10 audio setup instructions — no success.
I tried all 4 USB ports on my laptop — same result.
Even though the ifi iUSB3.0 permanently supplies 5V to the power line, I bought a Belkin externally powered USB 2.0 hub and put it between the laptop and the iUSB3.0 — no success.
Next I left the iUSB3.0 out of the chain — no success.
My wireless router is placed relatively close to the DAC thus I thought this could somehow mess it up. Perhaps the Yggy was more sensitive to radio waves so was the Wi-Fi disabled. No change.
Then I suspected that my USB cable was broken and purchased a PYST cable. The problem still persisted.
At this point I thought there's something wrong with my computer itself so I bought a Lightning to USB 3 adapter to connect my iPhone to the Yggdrasil. This setup gave me the same exact result; after a few songs the relay switch went off and that's it.
The only thing I learned is the longer the Yggy is turned off/disconnected from power the longer it works before it dies again. A heat-related issue?
By now I'm out of ideas. I ruled out everything I could think of but the problem still persists. What on Earth is wrong?
