I use an application called Equaliser APO to adjust Windows sound with FabFilter EQ (Pro-Q 2 or Pro-Q 3). It works fine for 1 month with either of the EQs, then suddenly stops working.
Every time I open an application that uses Windows audio, there is absolutely no sound until I "fiddle" with the Pro-Q 2 or Pro-Q 3 band settings or disable/re-enable the plugin.
This isn't an issue with Equaliser APO as it works perfectly with Pro-Q 2 for exactly a 1 month period (I timed it), then suddenly stops working. Then I have to use Pro-Q 3 instead. This also works for exactly a 30 day period and then suddenly stops working in the same way.
Therefore, I presume it's a licencing issue with the plugin and nothing to do with the application itself (Yes, I did purchase these plugins and they're activated properly).
Furthermore, the application works perfectly with other FabFilter plugins when they're run inside of it, even after having issues with Pro-Q 2 and 3 stopping working after 1 month respectively. I tested FabFilter Saturn for 1 month and the exact same thing happened.
Is there any way I can "renew" the licences to these plugins? I've tried reinstalling them and this doesn't rectify the issue. The only workaround is if I reinstall an old system clone every two months after having used Pro-Q 2 and Pro-Q 3 until they both stop working, but this means I have to reinstall any recently installed software too.
I've also tried other applications such as "VB-Cable Virtual Audio Device". The exact same behaviour occurs. One month in, the plugin stops transmitting audio through them and I need to "fiddle" with an EQ band every single time I want to use an audio application that uses Windows audio.
Sorry for the long post. Hope it explains everything in enough detail.
