[Bug 1914986] [NEW] KVM internal error. Suberror: 1 - OVMF / Audio related

[Toolybird]

Public bug reported:

This is latest release QEMU-5.2.0 on Arch Linux running kernel 5.10.13,
latest OVMF etc.

I'm seeing the following crash when loading an audio driver from the
OpenCore[1] project in the UEFI shell:

Here's the QEMU command line I'm using:

qemu-system-x86_64 \
-machine q35,accel=kvm \
-cpu host,+topoext,+invtsc \
-smp 4,sockets=1,cores=2 \
-m 4096 \
-drive 
file=/usr/share/edk2-ovmf/x64/OVMF_CODE.fd,if=pflash,format=raw,readonly=on \
-drive file=OVMF_VARS.fd,if=pflash,format=raw \
-usb -device usb-tablet -device usb-kbd \
-drive file=OpenCore-0.6.6.img,format=raw \
-device ich9-intel-hda,bus=pcie.0,addr=0x1b \
-device hda-micro,audiodev=hda \
-audiodev pa,id=hda,server=/run/user/1000/pulse/native

The driver loads fine when using the "no connect" switch. eg:

Shell> load -nc fs0:\efi\oc\drivers\audiodxe.efi
Shell> Image 'fs0:\EFI\OC\Drivers\AudioDxe.efi' loaded at 7E3C7000 - Success

However, the crash occurs when loading normally.

Any ideas? Thanks.
