I have a new Lenovo Chromebook 14 Plus. It is a wonderful laptop, great OLED screen, powerful Mediatek CPU, good keyboard.

Connecting a USB DAC, I see that all audio gets resampled to 48kHz. I guess this is the default used by Chromium OS Audio Server (CRAS).

Is there any way to get CRAS to bypass resampling and send bitperfect audio to a DAC connected via USB?
