Wired UPNP vs Wireless UPNP

[eniriop]

When streaming 24/96 files wireless from Qobuz with Audirvana and UPNP on the Macbook, the music would pause 2 to 3 seconds every now and then. But after hooking up the optical cable from the macbook to one Phantom, it plays perfectly every time. All CD quality files play without problem on wireless UPNP. But I have a 2015 Macbook. The newer ones have no optical connection in the headphone plug apparently,
