Actually, the 20% story is coming directly from iQaudio manual V.20 :
"connect from web browser to moode.local
select configure from the pull down menu, then system.
Within the Audio section select the IQaudio device you have (such as Pi-DAC+) and press SET
Within the same selection make sure you set the volume to around 20% (not 100%) and press SET
Select reboot "
I am currently using moode only.
And I only use the settings available through the (G)UI. I followed exactly the procedure described in iQaudio manual.
This evening I will do some test. I think one solution could be to set Alsa to 100% in the UI, but use a setting of -6 dB for the analog volume. In my opinion this should result in a lower output level and avoid the problem of "too loud and distorted sound" that I am experimenting.
Another approach could be to find a solution to limit the level at 50 or 75 % in alsa.
This way, I hope have a final output of the same order as my CD player typically.
The point is to find a way to definitely be certain that I am using the DAC card as it should be (for the best sound quality perf) and avoid over loud setting even when moode is used as renderer from Android bubbleUpnp for example.
The full config is:
moode running on raspberry Pi 3+ with iQaudio DAC-pro connected to NAIM integrated amplifier.
Usage : moode controlled from web browser (mostly for web-radio listening), or from bubbleUpnP or from idevice (shairport-sync)
