Suggestion for Universal PCM 384 kHz Support for PCIe Sound Cards

Currently, Windows’ built-in internal audio drivers only support 24‑bit / 192 kHz PCM, which prevents high-end internal sound cards or DACs from playing 32‑bit / 384 kHz PCM high-resolution audio without manufacturer drivers, limiting transparency and airiness.

We suggest Microsoft:

Add 32‑bit / 384 kHz PCM support while preserving native hardware sound.

Provide a native pass-through mode to avoid extra DSP processing and retain transparency.

Maintain backward compatibility for lower-resolution audio playback.

This would allow users to enjoy high-resolution audio even without manufacturer drivers, improve Windows compatibility with high-end audio hardware, and strengthen Windows’ position in the Hi-Res Audio market.

I’m talking about supporting PCIe sound devices, not USB.

It is hoped that the next-generation system will support universal 32-bit / 384 kHz PCM

    Hi, I understand how important it is to get the best audio quality from your PCIe sound card.

    The reason you’re not seeing 32‑bit / 384 kHz support is because Windows’ built-in audio stack currently tops out at 24‑bit / 192 kHz for PCM, so anything beyond that requires the manufacturer’s driver to unlock full capability.

    To check if your card can run at higher rates, open Sound Settings then click Device Properties then go to Advanced and see the available formats.

    If 384 kHz isn’t listed, try installing the latest driver from the card’s manufacturer and confirm WASAPI exclusive mode is enabled in your playback software for bit-perfect output.

    Do you usually play Hi-Res files through a specific app like Foobar2000 or JRiver, or are you relying on system-wide audio?

    Knowing that will help me guide you on the best setup for transparency and pass-through.

    Regards,
    Aron
