Default apu2 beeping

I installed OpenBSD 6.3 on an apu2-c2 system a few months ago. I configured it as my router, and it seems to be functioning normally.

Recently, the system has starting to emit a loud beep on occasion. The beep is very loud and sounds like a pulse of a fire alarm. Does anyone have a guess as to why this is happening? Are there log files I should be looking at?

I attempted to disable the pcppi0 and spkr0 devices through config, but I still hear the beeps.

Maybe show the output of 'dmesg' , it will be long , but that would give every one all the details on this hardware, and it might even show a error message that explains why the beep occurs.

Disconnecting or disabling the speakers won't fix what ever is causing the beep any way,
If it is from the bios, and the internal PC speaker, it might be significant of something that needs attention.

Not very descriptive, maybe better details, like what the occasion is , specifically ? Or is this when it boots ? There are ways to disable the beep at boot time, if that is all it is, and you find it annoying.

I can't discern any rhyme or reason for the beeping. It seems to happen randomly, perhaps once an hour. Here is the output of dmesg.

Some searches yield some interesting information, the 'dmesg' output will be usefull , but any way, this was one rather humorous work around, I just wanted to share:

In fact, it was not a system beep, it was a BIOS beep and there was not any option to disable it there. But there is always some workaround. Now I enjoy absolute silence.

I just disassembled the buzzer and removed the vibrating membrana. This was the only way to force it get mute. There was no option in BIOS to turn off the self test sound, and it was very loud and annoying. After all, silence is more valuable than a 200-dollar PC.
