This example opens separate OSS capture and playback channels in mmap
mode, places them into a sync group, and starts them together so both
ring buffers advance on the same device timeline. It then monitors the
capture mmap pointer with SNDCTL_DSP_GETIPTR, converts that pointer into
monotonic absolute progress using the reported block count, and copies
newly recorded audio from the input ring to the matching region of the
output ring.
The main loop is driven by an absolute monotonic frame clock rather than
a fixed relative usleep delay. Wakeups are scheduled from the sample
rate using a small frame step similar to the SOSSO timing model, while
the audio path itself stays intentionally simple: just copy input to
output, with no explicit xrun recovery or processing beyond ring
wraparound handling.

This allows the image build to work even if the host's OSVERSION doesn't

Also fix the image name so that Podman/Buildah will fetch it

These scripts have not seen the necessary changes to keep them up to
date with current KPIs and coding practices. They use I/O ports directly
rather than any bus abstractions, use i386 (which is on the way out for
kernel configs) as the architecture of choice for generated kernel
configs, use ISA KPIs, use INTR_TYPE_FAST (renamed in 2000 to INTR_FAST
and removed in 2011), and likely have other issues too that render them
more harm than good for the uninitiated developer looking for a driver
template. If anyone wants to invest time in modernising them they can do
so and bring them back, but for now delete them.

For now, we enumerate disk devices before network devices. This is to
work around a problem wherein u-boot remaps BARs during boot in a way
that bhyve does not handle. Some discussion and experiments suggest
that this can be handled by having bhyve not map BARs during boot on
arm64; until a solution is implemented, however, this workaround is
sufficient for simple usage and doesn't have any real downsides.
The console and bootrom are specified slightly differently versus amd64,
and a few of vmrun.sh's command-line options are amd64-only.
