Audio speed and pitch halved with 192k 32, no audio with 384k 32

i tried the script on my Google Pixel 6 and when i change the sampling to 192k 32 any audio played is halved in playback rate and pitch. using 384k 32 there is no audio at all.

Pixel6's cannot replay tracks over 96kHz without usb_samplerate_unlocker (up to 192kHz for Pixel's) because of their platform configuration.

This is normal behavior.

what is the benefit that this script brings to usb-samplerate-unlocker? changing via command line?

usb_samplerate_unlocker extends only the capability of the Pixel6's original sample rate range [8 ~ 96] kHz to [8 ~ 192] kHz. The sample rate of a USB DAC isn't changed at this point, usually 48kHz for 44.1kHz tracks and 96kHz for hires. ones.

This script can change the rate in [44.1 ~ 192] kHz range on the fly by executing it with options.

By the way, Tensor devices are poor in this point, but others are can be extended the rage to [8 ~ 768] kHz.
