I'm on an early '08 Mac Pro 5,1. Is it possible to install more audio output ports? For the ideal system that I will gradually try to achieve, I would have the headphones out, + 3 other outs. So that's one output short. If it's possible, could you please suggest the correct component – the anatomy of a computer it still relatively new to me so I don't trust myself in identifying compatible components. When you already have the hardware, it's relatively easy to find teardowns and other illustrated guides. If you're about to suggest Bluetooth speakers, external audio interfaces or mixers, please see below. Otherwise, this doesn't need to be elaborated Spoiler: Q&A for why it's an internal output that I'd prefer. Q: Why not split by using a mixer? A: I'm doing this currently and it isn't ideal at all because it's fully manual. I have a small desktop mixer mostly for recording purposes, and it also serves as a physical volume controller for my main speakers which don't have one of their own. But the mixer is one more nasty looking device cluttering up the work area when it wouldn't necessarily have to be there; For the volume knob-less speakers I'd rather get a standalone volume controller. The mixer in between is one more electrical device plugged to the mains which contributes to heating and use of electricity, and it's one more device that has to be switched on and off in the correct order when I start/stop using the computer. Awkward. Q: Why can't it be an external device? Such as a USB/Firewire audio interface? A: Two reasons. One, because I'd rather not collect any more individual physical manually operated mains devices to the working area, if possible. Two, because when I'm about to start doing something I launch a 'context' that includes the automatic adjustment of multiple factors in the environment. For the audio output, this means that I want the switching of the audio output to be Applescript-commandable. You can't do this if the splitting is done by an external device that has a logic of its own. Q: Why not get some Bluetooth speakers? A: They DO seem to be taking over the market, a lot! But after reading a lot of reviews, for speakers, I can only find BT a major annoyance and a potentially short-lived fad: Bluetooth means software, which is one more thing that can malfunction, and if it does, the stuff today isn't really meant to be repaired, just disposed of. Some BT speakers have automated behavior which you can not change, one that can either be very annoying to you, or again, not work as it should: Speakers auto-shutdown after a certain amount of time; Speakers make a sound signal to indicate when they're on or off; Speakers can be paired with a device freely, meaning that other people can accidentally/purposefully connect to them without your consent. Speakers develop connectivity issues so that that the sound quality either isn't very good, it comes in and out, or you have to fight with the pairing. What can I say – I like simple, wired, personal speakers that only have one job. My main ones are decades old, work flawlessly, and don't have the "emotional problems" that "smart devices" can have.
