Schiit Yggdrasil II

Description Of Issue

I just updated my Mac to os Catalina 10.15.4 and since then the Mac do not see the Yggrasil via USB anymore.
Any suggestions?
Thank you,

You do not need drivers for Mac or for Linux distros that support UAC2.

Can you see it in Audio MIDI Setup? Can you select it in Output Settings?
Apple menu > System Preferences, click Sound, then click Output.

I did and can’t see the dac anymore.

If it’s not showing in MacOS either, then its not specifically a Roon issue. You could check if it’s detected in System Information > USB, or try Schiit support?

Thank you Mike.
I’ll do.

Hello @Vassil_Pertchinkov, were you able to detect your DAC under “System Information” as MJB suggested? Let us know!

The DAC works on the previous version of Catalina but can’t be find in 10.15.4
Not visible in System info or Audio devices in Audio Midi.
Just talked to Apple-they are not aware of a problem.
Just contacted Schiit for updated driver, if any.
Looks like I can downgrade to older Catalina version or wait for new update on Catalina.
