[9fans] qemu sound, only one side/speaker working

So last year a patch was submitted to fix 9front's sound under qemu as a guest (using intel hda)

But it's semi broken again.

With a linux host using pulse audio, audio in qemu with a 9front guest only plays on one side/one speaker.

here's my startup cmd

qemu-system-x86_64 -cpu host -enable-kvm -m 4024 -net nic,model=virtio,macaddr=52:54:00:00:EE:03 -net user -device virtio-scsi-pci,id=scsi -hda 9front.qcow2.img  -boot d -vga virtio -display sdl,gl=on -device intel-hda -device hda-duplex

just tested with QEMU 5.1.0 (v5.1.0-11824-g8699890d91-dirty) under windows 10.

it works just fine for me.

i doubt this is a bug in the hda driver. the left and right channels are submitted
as one stream. the fix of last year was about command completions requiering the
interrupt driven method in qemu, while the driver was just implementing a simple
polling scheme.

so i suspect it to be a problem with your specific qemu version or pulseaudio.
