Low volume on RPI4 with usb dac


I have a Raspberry PI4 and volumio installed. I connecting FiiO K5 Pro to an usb.

The problem is the output volume is lower than when i connect dac to PC, i was do a A/B testing and Raspberry has lower volume.

In volume settings in volumio volume control is set to none.

I typed in ssh alsamixer and this is what i got. It looks like software volume control is enabled and it’s not a bit perfect.

try to enable software mixer in volumio, save, reboot.
Disable volume control again and reboot.

You haven’t installed any other plugins like DSP?

Nie instalowałem wtyczek dsp.

Enabling software mixer and disabling still not help.

Let hope some community user has more experience with this DAC
