Audirvana Studio equalizer issue: works with USB but not with UPnP
I’m experiencing an issue with the new equalizer function that was recently added to Audirvana Studio.
Situation:
Works correctly: When I connect my audio device to the Mac via USB connection, the equalizer applies perfectly and I can clearly hear the audio modifications
Doesn’t work: When I use the same audio device via UPnP connection, the equalizer has no effect on the reproduced sound
Questions:
Is it normal for Audirvana Studio’s equalizer to only work with USB connections?
Are there any particular settings I need to configure to make the equalizer work with UPnP devices as well?
Is this a technical limitation of the UPnP protocol or a software bug?
Technical details:
Software: Audirvana Studio (latest version)
Operating system: macOS
Audio device: [insert your device model]
Connections tested: USB (working) vs UPnP (not working)
I would really appreciate a technical explanation of why this difference exists, as I find the equalizer function truly fantastic when it works.

If you want to tweak the EQ while music is playing , there’s one more switch to turn on:

• Enable “Realtime control (not for DSD playback)”
• You can still use the EQ on your DSD files or while playing using UPNP or Chromecast, but not in real time. To do so, disable “Realtime control” and press “Configure” under “Use Audirvāna EQ” to design your EQ before playing the track.
