Hi, after installing BluOS 4.12.4 on my Powernode N330 today I noticed that the subwoofer output is much louder than before. I'm using the Home Theatre Group with Dolby Digital input (PS5 into LG C4).

Though the subwoofer output with Dolby Digital has always been quite low in my opinion, I’ve came up with some (Music / Cinema) presets (iOS shortcuts) that work around this by changing the groups' tone controls, but these, along with the sub volumes, will now all need to be changed and be retuned.

So before doing this; is this change a bug or a feature?

Update 1: Testing with Tidal Connect also reveals an obvious increase in sub output, additionally the Stereo Surround feature no longer seems to work at all (I use this often for live albums).

  On my NAD M10 V3 they just rolled back to BluOS 4.10.19.

  The 4.12.4 update was full of bugs specially with DIRAC.

  I also lost stereo surround feature after the update. 5.1 content plays fine but no stereo surround. I am running NAD M10v2 with Pulse Flex 2is as rears.
