This meant that Apple Macbooks with apple-gmux as the gpu switcher no longer had the audio client registering, so when the gpu is powered off by vga_switcheroo snd_hda_intel is unaware that it should have suspended the device: amdgpu: switched off snd_hda_intel 0000:03:00.1: Unable to change power state from D3hot to D0, device inaccessible snd_hda_intel 0000:03:00.1: CORB reset timeout#2, CORBRP = 65535 To resolve this, we use apple_gmux_detect() and register a vga_switcheroo audio client when apple-gmux is detected.
