Attached is a modification to get Input and Filter setting directly into moode.

Just to confirm, only the 9028/38 q2m dacs sold in 2019 support the chip options ??

Only the post 2018 DAC support the 7 filters settings. The others one support only 3 filters settings.
Other parameters works with both board version.

That's why in the plugin I wrote some parameters between ()
The first boards revision will only use these parameters.

Ok got it.

Regarding the input switch, is the audio routing is handled entirely on the board?

In other words there is no need to run alsaloop to route ALSA in to ALSA out.

Here's some screenies that show how the DAC's are integrated.

- There is an additional entry for the pre-2019 DAC.
- The "input select" option is part of moOde's universal Source Select feature
- moOde 5 will be shipping with kernel 4.19.34 or higher which provides the new Audiophonics i-sabre-q2m driver that exposes these nice options :-)

                           

Tapping on the title in the center opens the Source Select screen

Yes the input switch is hardware, so the signal is directly processed by the ESS chip.


Input setting display is very good, thanks for your work Tim !  Cool
