[Libguestfs] [PATCH] lib: direct: Set QEMU_AUDIO_DRV=none ...
https://listman.redhat.com/archives/libguestfs/2019-March/msg00128.html
This happens because the qemu audio driver can't be set up without a console. We can suppress this by setting the environment variable QEMU_AUDIO_DRV=none, which is the same thing that libvirt does, and also the same thing that we are already doing when launching the real appliance subprocess.

Instead of exportI've had to use setcommand on Windows 10, also &&didn't worked, so I've only ran these two commands set QEMU_AUDIO_DRV=noneand then emulator -avd Nexus_4and can confirm that sound is now really disabled in QEMU. Also problems like 40-100% CPU drain, after few hours of emulator inactivity are gone. – tekk Dec 7 '16 at 3:06 1

Note that setting QEMU_AUDIO_DRV to none is just to suppress error messages from QEMU about missing configurations for the audio drivers, which we do not use. As with the BeagleBone Black, this will end with a kernel panic and the system will halt. To exit from QEMU, type Ctrl + A and then x (two separate keystrokes).
