Don't use SFX/MFX/EFX

[john-peterson]

because it doesn't work

communication streams don't call mfx

we have to use gfx instead of mfx for post-mix because communication streams don't call mfx, they only call efx

In Windows 8.1, a render audio stream opened in communications category is always opened in raw mode. Any must-have effect, such as speaker protection, must be implemented as an endpoint effect (EFX), which is an always-on effect.

by disabling sfx/mfx/efx everything fall back to lfx/gfx. including modern skype

better than using sfx/mfx/efx

this is better than using sfx/mfx for pre-mix and efx for post-mix because

• the sfx/mfx/efx result is identical at best to lfx/gfx because EqualizerAPO dont use any APOInitSystemEffects2 features

• we don't know which of sfx/mfx/efx are pre-mix and post-mix because there's almost no docs or samples for it. capture devices have no gfx. we don't know which of sfx/mfx/efx it has

• sfx or mfx for pre-mix together with efx for post-mix fail. the audio playback is silent and create this endless Initialize loop https://www.dropbox.com/s/ghrh2ij0di3wd8m/EqualizerAPO.log?dl=0. my config.txt is

  Preamp: -30 dB
