Audio sample rate of 384000 not supported on Windows

It appears as though audio sample rates of 384000 are not supported on Windows.

If you use, for example, the s/w only HIFI-Cable driver from here: https://vb-audio.com/Cable/ (The driver half way down the page, not the one at the top) - Windows System > Sound > Hi FI Cable Input / Hi Fi Cable Output > Format both show 24 bit 384000 Hz (Studio Quality) as an available setting,

However, QAudioDevice::maximumSampleRate() for this device returns 192000.

The variable allSupportedSampleRates in https://github.com/qt/qtmultimedia/blob/dev/src/multimedia/audio/qaudioformat_p.h is missing 384000. Not sure if that is the only relevant bit of code for this.
