Why is airplay used form steaming and not wired ethernet that is connected and sample frequency downsized while my Linn can handle 192Khz.
How can I optimize these settings
Probably by going to “Settings” then “Audio” and selecting the proper connection there.
(I’m not a Linn user, btw)
EDIT:
First check “Settings” “Setup”, look for and edit “Subnet for Linn streaming”…
I don’t own an Akurate, but I own two Klimax and I’ve owned Selekt as well. In all cases, one of the options that shows on Roon’s Settings>Audio>… is to enable them as “Roon Tested” Linn streaming devices. However, you may also have to make sure the DSM has Roon configured as one of its sources, via the Manage Systems page on your Linn Web account or via one of the Linn apps.
