Continuing the discussion from Roon 2.50 Build 1528 is Live!:
I just updated both the server and the Roon app on my MacMini and am noticing a lot of clipping, even with leveling:
I haven’t experienced this before this update and wanted to check if there’s anything wrong on my end or if this is related to the update.
In Headroom have you got the clipping indicator set to on?
Is the signal path indicator turning red when this clipping is occurring?
Does it occur when you turn off the 7 band PEQ?
Might be worth seeing a screenshot of your seven band PEQ screen
Yes to both, thank you.
For now I fixed things by using DSP volume control for my DAC, which gives a good sound without clipping.
You need a lot of headroom for an EQ like that. I would be surprised if that is not the issue.
As a rule since decades ago I just assume there is (or could be at some point) no headroom so all my EQ (at any point in any signal path in music production or listening) is subtractive. You could have the same shape of EQ doing that, just ~10dB quieter.
On this last signal path you posted, if there is anything additive in your parametric EQ you would only escape clipping if the source track happens to be very quiet, or if there was nothing additive in your EQ.
If the source track were a modern track (with usually no headroom at all) and you add anything at all in the EQ stage, you’ll already have clipping before the -18dB later on, which won’t fix any audible clipping, just turn the volume down. So I would suggest testing with a modern loud track and looking at your EQ as it is now applied.
edit: the black bar to the right of the para EQ in Roon can be used to easily push the whole of your EQ curve down (or up) if it is the source of clipping where there is little/no headroom.

@Cosmin_Tataru is the correct solution for your needs based on the PEQ screenshot.
