the Pipo X8 uses Intel's Bay Trail-T SoC (Atom Z3736/Z3740), and Pipo never published standalone chipset drivers. The common, reliable workaround is to use Lenovo's official "Intel Platform Device Driver" package for the ThinkPad 8, since it's built on the exact same Bay Trail platform and includes the Intel SST Audio Device (WDM) driver plus the supporting PMIC/I2C/GPIO drivers that audio depends on (Bay Trail audio often breaks after Windows Update because it clobbers these dependency drivers, not just the audio driver itself).

https://support.lenovo.com/us/en/downloads/ds040016-intel-platform-device-driver-for-windows-10-32-bit-81-32-bit-thinkpad-8

Check Device Manager first — open Device Manager and look under "Sound, video and game controllers" and "System devices". If you see a device with a yellow warning icon (often shows as "SST Audio Device" or an unknown ACPI device), that confirms the audio driver got wiped by the update.

Download the package from the link above (it's a Lenovo-signed installer, not a bare .inf, so it installs cleanly on 32-bit Windows).

Run it as Administrator. It will detect and reinstall: Intel SST Audio Device (WDM), the Power Management IC driver, I2C/GPIO/SPI controllers, and the Dynamic Platform & Thermal Framework drivers — all of which the Bay Trail audio stack depends on.

Reboot after install

    For a 32-bit Windows Installer package, the platform field must be "Intel". On x64-based Windows, 32-bit drivers are not supported, so a 32-bit driver package will fail to install there.

    For the audio/video issue after Windows Update on this device, the supported recovery steps in the available guidance are:

    1. Install the latest Windows updates:
      • Start > Settings > Update & Security > Windows Update
      • Select Check for updates and install all available updates.
      • Restart the device.
    2. Update the audio driver:
      • Open Device Manager.
      • Expand Sound, video and game controllers.
      • Right-click the audio device and select Update driver.
      • Complete the wizard and restart.
    3. If sound stopped immediately after the update, roll back the audio driver:
      • In Device Manager, right-click the audio device > Properties.
      • Open the Driver tab.
      • Select Roll Back Driver.
      • Restart the device.
    4. Restart Windows audio services:
      • Press Start, type services.msc, press Enter.
      • Right-click Windows Audio > Restart.
      • Right-click Windows Audio Endpoint Builder > Restart.
      • Test audio.
    5. If the issue started after installing the Intel Smart Sound Technology driver version 09.21.00.3755, install the Microsoft fix for impacted systems. It is delivered automatically through Windows Update, and a stand-alone package is also available from the Microsoft Update Catalog.
    6. If the problem followed a BIOS update, reinstall the HD audio device drivers and restart the computer.
