Do you have Automute enabled (unmuted)? If yes, then it looks like it
is not working. If no, then it works all right.
In earlier alsa releases, Mac Mini was using the same snd-powermac
driver as did all older PowerMacs. But I assume that Debian Unstable
has the support only in snd-aoa (AppleOnboardAudio). You can check
which you use with:
lsmod | grep ^snd

What do you mean with pcspkr? Isn't it the same as built-in speaker
and internal speaker. You mean the beep? That's how it was called in
snd-powermac driver of which I have experience (not on Mac Mini,
though). There is probably no separate speaker for beep. The
implementation in snd-powermac generates PCM sound and plays it out
through the normal channels. I was able to see that in dmesg output
there was a line saying something like: PowerMac Beep attached to
.../input...
Do you have a control named Beep?
It can also depend on the terminal emulator and its settings. All
terminals probably won't produce the beep sounds.

I assume that you get what the driver gives you. It looks like the
implementation could be better. But don't take my word for this.
