I want to switch back and forth from digital and analogue sources. The Raspberry Pi hosts the world-class Audirvana music player. That's the beauty of this RME device.

But then no RasperryPi nor iPad or any computer is need, right ?

Disconnect USB
crank up the volume of the amp
or use a DAW with a limiter/maximizer

You can record in Reaper and normalize the recorded file.

Low analogue input volume on ADI-2/4 Pro SE

I am running the ADI-2/4 Pro SE connected via USB to a Raspberry Pi running Dietpi (Debian ARM). This allows me to perfectly digitally stream DSD level quality through the ADI-2/4 Pro SE. However, I also have a turntable connected via the analogue input of the ADI 2/4, and that is often at a very low volume. I need to unplug the ADI 2/4 from the Raspberry Pi and plug it to an iPad or a Mac to achieve a proper listening volume in analogue mode from the turntable.

I do have the RIAA amplification set to high gain, so that is not the issue. It's enough to connect it an Apple device to restore it's proper volume. In a previous thread, RME has informed me that this low volume is set by the USB connected device. That means the Linux is lowering the volume of the ADI 2/4.

Does anyone have any knowledge on how I could fix that? I've tried ChatGPT, followed many instruction on how to setup volume at 100% in the Linux OS (Dietpi), but nothing works.
