Built-in Dirac Live not working with upmixing or other modes

[keks8430]

Hi,

Is DL supposed to work with DTS Neural:X turned on?
The Onkyo NR7100 manual lists certain limitations of decodings with DL, but I found none for DTS Neural:X.

The test sound is a 2-channel pink noise, same for both fronts.

Played in Stereo mode, the target curve is clearly visible, without my room's mode peak +20dB@42Hz.
When switched to DTS Neural:X, the decoder correctly figures out that both channels are carrying the same signal and redirects it to the center speaker. But now my target curve is gone and the mode peak reappears.

So, either DTS Neural:X turns off DL, or the upmixed signal is not processed by DL.
Either way they do not seem to work together.
Just confirmed that (for a 2-channel signal) only Stereo uses DL, all other modes - including Allch Stereo - turn DL off.

Bug or missing feature?

As confirmed by Onkyo, the actual firmware contains a bug in the bass management. If there is no subwoofer, the bass redirected to the fronts is not DL corrected.

Since the fix so far has not made it into into an official update, I am sharing the link to the bass management fix Onkyo sent me.

There is now a firmware update available via NET, but no information yet about what features or bugs are addressed.
