Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

And do you agree that this is a very important function? I would say, basic function?

Legacy connections stay legacy unless it is very clearly indicated that they have changed. Asus does not say in the manual it has changed. The speaker signal is still +5V-speaker, as it has been for decades. Not speaker-GND as would have been likely for a DC output. The 5V-speaker is constructed as such so an open-collector output can be used to drive the speaker.

Besides, if you have an ATX case in which you can mount this MB which still happens to have a conventional AC-drive speaker a modern ATX mainboard would not be able to drive the speaker? Can't believe that.

Please notice the writer in the quote is addressing some person who I do not know. Also, there is a difference between piezo buzzer and piezo speaker.

If the system doesn't boot due to hardware malfunction you have to open the case anyways, so you can hear even low volume beeps.
In normal usage I don't think that the PC-speaker is important anymore, most terminal emulators support visible bell indicators and audible bells through the sound system.

Well, the more simple a system is, the more reliable it is, other things being equal. Anyways, it's only a slight difference in opinions. And it is possible, besides, that you have much greate knowledge and experience than I do.
