enable WASAPI Exclusive ?

[Sennheiserman]

hello

i know that vlc uses wasapi but how can i enable exclusive mode?


i need exclusive mode to play files like they were encoded.
for e.g.

file format -> output

mp3 16 bit 44,1 khz > 16 bit 44,1 khz
dvd/blu ray 48 khz > 16 bit 48 khz
flac 24 bit 196 khz > 24 bit 196 khz


with wasapi shared mode the windows device settings are used for output for e.g.
windows device set to 16 bit, 44,1 khz

mp3 16 bit 44,1 khz > 16 bit 44,1 khz
dvd/blu ray 48 khz > 16 bit 44,1 khz
flac 24 bit 196 khz > 16 bit 44,1 khz


windows device set to 24 bit, 196 khz

mp3 16 bit 44,1 khz > 24 bit 196 khz
dvd/blu ray 48 khz > 24 bit 196 khz
flac 24 bit 196 khz > 24 bit 196 khz


to avoid up and down sampling i need exclusive mode
mpc hc, mpc be, dvdfab player, power dvd, etc. support wasapi exclusive mode
how can i enable exclusive mode in vlc to play files with audio frequency like they are encoded?


thx

In this thread a dev says there is a flag for WASAPI exclusive mode in the preferences, but I can't find it anywhere:

The wasapi-exclusive configuration flag exists for this.

thx for the info
and where do i find it?

i use vlc 3.0.18
i looked under preferences -> all -> audio -> output modules -> MMDevice -> output back-end
there is a wasapi flag but no exclusive option


edit:
i tested latest nightly 4.0 version
there is an option for wasapi exclusive but it doesn't work (yet)
the audio device is empty in main vlc window under preferences
so there is no audio output with wasapi exclusive

tested with 32 and 64 bit version
without wasapi exclusive there is audio output despite audio device is not show
