In the device settings decode and render is activated:

But I had to disable MQA-Core-Decoder, because otherwise Roon is unable to play to the amp, because “it’s loosing connection”

Diagnosed it furthermore - it seems to work, when disabling the automatic volume adjustment?

@support any idea on this specific issue?

Hi @Kersten_Kusch ,

Can you please clarify on this? Do you mean to say disabling volume leveling for the zone allows correct playback? Are you using the latest firmware on the DAC?

Hi,
disabling this option: image
resolves the issue and allows correct playback. The module is using version: 3.12.13, which is the latest.

Hi @Kersten_Kusch ,

Can you please confirm that you have the latest BluOS firmware installed? There was a recent update that may have helped with this behavior, can you please verify? Thanks!
