On my laptop (and probably most modern laptops) the old-fashioned "PC speaker" is not a physical piece of hardware on the motherboard: it is purely virtual
No, not really virtual. At least I do not think so, for two reasons: - Sound chips (some, at least, maybe "many") have an input line for the PC speaker if you look at their functional block diagram. For example the AD1812 (which calls it just "MONO"). - x86 motherboards already have all the magic to make analog sound using the PIT, and the firmware that goes along with it. It is easier to just wire that in analog mode into the MONO line of a soundchip than it is to rewrite the BIOS/firmware to issue digital commands (ever-changing API!) to have a soundchip autonomously produce a squaresine wave. I am not saying it's impossible, but it seems overkill, and it's not like you are going to do Hi-Fi over pcspkr anyway that you absolutely need a digital transport. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
