Description Of Issue

After reinstalling a fresh copy of MacOS I’m having problem with the volume control in Roon.
It doesn’t seem to matter whether I choose DSP or Device Volume, I still get 100% output no matter how much I use the volume slider in Roon.
I really can’t see what’s wrong.

Any ideas?

Hi again!

Sadly it does seem that the volume output from Roon is stuck at 100% whatever type of output I try to use. If I select device volume is 100% regardless of what the volume slider says. If I choose DSP the slider will be at -2147483 and will not be possible to move. Audio output is still at 100%

Volume control worked just fine before my reinstall so I just can’t figure it out.
Anyone who’s seen this problem or know how to fix it?

[Thomas_Rosander]

Problem solved partly. It appears that disc permissions was wrong and that triggered the behavior in Roon. However only DSP Volume works, Device doesn’t.

Hello @Thomas_Rosander,

Glad to hear you’re back up and running. Just so you’re aware, the Mytek Manhattan II does not support “Device Volume” via its USB input.
