[Solved] Reduce Gain DAC?

Hi Everyone,

I’m using actually Volumio since a while with Nanosound DAC (1st generation) with volume disabled connected to a Sansui AU-717 amp, I’m pretty happy with the results, the thing is when I play music, the DAC outputs quite high volume/gain so I have to set the Sansui’s volume very low, almost 1-2 steps from the minimum, so I would like to ask you whether there’s a way to reduce the gain of the DAC to something like 50% keeping the volume mixer disabled, I’m aware that volume itself tunes the gain but if I activate software volume it will reduce sound quality and hardware mixer makes nothing to the volume, just doesn’t react.

Any hint will be appreciated!



Both NanoSound DAC and DAC2 should support hardware mixer.

Can you please try this:

- In playback options page, set i2s to OFF

- Reboot

- Follow this guide to set back the playback options. Look for “Output device” in this guide

Hi, Thanks a lot, that link made the trick.. I misconfigured the volume options... my mistake I didn't check the documentation in support..
