Help! W13: Mix sounds okay, but rendering/exporting ruins it completely

[Axxxeman]

Hi folks, recently, when buying a new PC, I changed from W11 to W13. And since that time I got a massive problem. I am recording mainly radio shows (some are word-based, some are music-based) and radio jingles / teasers.
The problem is that since I changed from W11 to W13 the mix sounds absolutely okay, but when rendering the file, it is terrible. It seems that on rendering, the plugins are simply ignored. Furthermore an Automation on one track seems to affect all other tracks as well, which is absolutely inacceptable.

A small example as explanation: One of the projects has only 2 tracks, one for background music and one for the voice-over. I am using the inline mixer with the usual plugins "Volume & Pan" and "Levelmeter". Additionally I am using an Exciter plugin (La Petite Excite) on both tracks (with individual settings on each track). I had the plugin verified in W13 and it works as it should in editing mode. On the music track a volume automation is set to reduce volume, while the voice is on.

As I said, the mix sounds perfect. But when I export the finished work, two unwanted things happen: The Exciter plugin is absolutely ignored. And the voice volume, instead of standing out clearly (as in the mix) is reduced just like the automated music track. As you can imagine, the result sounds terrible.

BTW, the outputs of each track are set exclusively to the audio interface and the result does not change, when the outputs are changed, nor do plugins in the mastering section change the result. The Exciter-Plugin is ignored there, too. I did not have these problems in W11, so I guess, it is probably either a bug or some setting, which is different, and I just cannot find it ...

Any help / ideas are highly appreciated, because I need to hand in a few emissions within this week ...

Okay, sorry bothering you boys & girls, I found the problem and it has nothing to do with Waveforms 13 at all! I would have deleted this post, but could not find, how to ...

The problem is a combination of a faulty hardware component and a new Windows 11 feature my old PC (Windows 10) did not possess ... You see, in Windows 11 you can use different sound systems simultaneously, in my case ASIO for the DAW with studio monitors and Windows Sound System on some old standard PC speakers. Mixing is done on studio equipment, while Windows uses a built-in Media Player with the other sound system for the rehearsal of the result. And something with these old speakers does not work anymore, it's maybe a broken cable connection or maybe a bad plug. So some frequencies are missing on the final result and I really thought it to be a problem in the mastering process. Playing it on the studio monitors or on headphones and everything is fine again ...

Again, my apologies!
