The DAC+ DSP stops producing output (LED turns off) when the audio level gets low. Is there a way to configure what the cutoff is for this? It keeps switching off during quiet parts of music. I'm using it with a Pi 4B running stock Raspbian.

HiFiBerry team This can't be configured. However, it is at -80dB that should be fairly low. Are you sure, you're application is sending audio at full level or do you use some software volume control on the application side before sending data to the DAC?
Some users use the "noautomute" DSP profile that doesn't mute the output at all:

Ian Henderson I see -- it's part of the DSP program. Opening dacdsp-v11.dspproj in SigmaStudio, it looks like I can change the value in the Input Detection block. I'll mess around with this some more tomorrow (when I can be certain I won't wake up the neighbors), but I think I should be able to figure it out. Thanks for the quick response!

HiFiBerry team Yes, most functionality is implemented in software and depends on the DSP program you're running.
