NetBSD 10 Beta, RC1-6 and Pi Wifi and A/V

 Complex title, just to say how stable and feature-rich is NetBSD 10 on a Raspberry Pi (4)?

Pretty good, not bad, can't complain.

Wireless

At one time during RC (release candidate) testing I had wi-fi engaged on a Pi 3A, a 3B, and a 4. Beyond those, the Pi0W and Pi02W wireless has been unflappable on start-up, if a bit squeezed on speed, and an occasional miss of the beat. Since I took this screenshot, the 4 has lost the ifconfig (again), and the 2 3's are humming along. All of those are on the same GENERIC64 kernel.

I know there is a "symlink" fix supposed to repair the lost wireless interface; see below.
GOOD?:

A recent mail message contains the sym-fix:
In this image, a symbolic link added
/libdata/firmware/if_bwfm:
ln -s brcmfmac43455-sdio.raspberrypi,4-model-b.txt "brcmfmac43455-sdio.Raspberry Pi 4 Model B.txt"
to avoid
bwfm0: autoconfiguration error: NVRAM file not available
But I get a wrong address range assigned, so not yet solved.

Any tips welcome...

Audio/Video

Besides the ubiquitous VLC app (GUI and CLI), I've used mpg123 and mp3blaster on NetBSD systems as command line audio/video players. With a miniDLNA UPnP set-up and steaming internet radio stations I have good tunes at will. In the good old days. a SoundBlaster interface card was the way to go. Theses days, audio circuity is either built-in the system, or ready as easily as popping in a USB dongle. 

Prior versions of NetBSD on Raspberry Pi systems had challenges with the wired headphone circuit and with audio through HDMI (in some cases not the system fault but a lack of speakers in a monitor. The audio streams would play okay for a while but within a day or so various buffer/cache issues came up, causing no sound, or worse, choppy static.

I'm getting about a week of playing, at intervals, before contention creeps in.
