In case no sound hardware is present the driver initializes successfully and throws errors later on, i.e. effectively the automatic probing doesn't work. So the driver should not be used by default (until that is fixed). Drop the can_be_default flag.
Explicitly picking the alsa driver (using QEMU_AUDIO_DRV=alsa environment variable) will continue to work.
