Are you using a Coaxial SPDIF or Optical SPDIF connection to the Mytek Liberty?
Optical SPDIF devices will often struggle to maintain signal lock at rates higher than 48kHz. Generally, we see that most devices are reliable up to 96kHz, with 192kHz playback being dependent on multiple factors including the quality of the cable, how long the cable is, and if there are any excessive bends in the cable run.
For reliable playback at 176.4kHz or 192kHz, it is recommended to use the coaxial connections on the Node 2 and Liberty. Keep in mind that cable quality may also impact the reliability of high resolution playback with coaxial SPDIF, albeit to a lesser degree than with optical.
When you play 176.4kHz or 192kHz content to the Node 2, can you hear audio output on the Node 2’s RCA outputs?
In the Settings > Audio screen, make sure that you are not using the “System Output” or “Core Audio” zones for playback. When the Mytek Liberty DAC is connected, it should appear in this screen as a separate playback zone. Enable this zone, and ensure that the “Exclusive Mode” toggle is enabled in the Device Setup screen.
My Mytek Liberty DAC is not showing as a separate playback zone? When I try to “Configure Mac OS Devices” to see if the Liberty will show up it just runs and runs, I have let it run for 30 minutes or better and it just keeps running?
The Mytek Liberty should appear on this screen. Click the “enable” button next to the entry for the Mytek Liberty to enable the zone. You can then click the gear icon to head to the Device Setup screen to ensure that the DAC is in Exclusive Mode.
