My previous two NetBSD system's volume could be turned up with:

	mixerctl -w outputs.master=248,248

But my new system doesn't have that. I am not sure what is used to turn up 
the volume.

Playing with ogg123 shows something playing (using default oss). But I 
hear no audio.

I have:

NetBSD/amd64 4.0_RC4

My laptop has a volume dial that spins forever.

Any ideas on simply getting this to make sound?
