hdaudio.sys and hdaudbus.sys log WPP events using the same ETW provider.

You can gather these logs using this .wprp, but you won’t be able to read them 
without symbols, and the symbols aren’t public.

The interesting part of the .wprp is:

    <EventProvider Id="WPP/hdaudio.sys-hdaudbus.sys" 
Name="b3a109ec-1cb3-4947-95ed-431033eeb1b4" Level="5" NonPagedMemory="true">
      <Keywords>
        <Keyword Value="0x7FFFFFFF"/>
      </Keywords>
    </EventProvider>
