Now this seems to be an intermittent fault (I think I fixed it by setting VB-Audio Input Cable to 'Stereo' and then resetting it to '7.1 surround speakers'). All work fine (apart from front centre and subwoofer). So when in the Windows 'Configure' dialog and I click on the individual speakers in the picture. Then are playing (but are very very quiet). However, occasionally the front centre and subwoofer speakers will not work on the test. The Voicemeeter Banana compression also works. When I test the 7.1 in HeSuvi everything is again fine. When I configure VB-Audio Input Cable to 7.1 and test the speakers then all sound correctly. I can tell that the HeSuVi is applying the different HRTF filters (so that bit is working). * To that output I have connected a pair of Sennheiser G4ME ONEs. Then I am applying a VM Banana audio compression to that 'Hardware Input 1', before outputting the signal to my 'Realtek High Definition Audio' output. I then have Voicemeeter banana using the 'VB-Audio Output Cable' as the 'Hardware Input 1'. I am also applying an equalization curve to this, and have the connection mode set to 'Virtualization'. I hope taking a 7.1 surround sound input and applying the HRTF function to downmix it cleverly to stereo. I have used Equalizer APO to setup HeSuVi virtualisation on that input cable.

surround sound (so as to make applications / games think I have 7.1 surround sound speakers). How am I using this software? I am using the VB-Audio Input Cable as my default output sound. (ALC1220 codec) HeSuVi 2.0.0.0 (Latest Equalizer APO) VB-Audio Virtual Cable 1.0.3.5 Voicemeeter Banana 2.0.4.4 I have these pieces of software installed: Realtek HD Audio Driver 6.
