Your classic VGA setup will probably be connected to a CRT monitor, which among other things has zero lag, and therefore running your sound separately to your audio setup, which also has zero lag, will be fine. Audio and video are in sync.
HDMI cables will almost certainly be connected to a flatscreen of some kind. Monitors tend to have fairly low lag, but flatscreen TVs can be crazy. Some of them have “game” mode (or similar) but as for the rest, they might have half-a-second or more of image processing before actually displaying anything. Running sound separately will have a noticeable disconnect between audio and video; drives me crazy although some people don’t notice it. You would connect your audio setup to the TV rather than directly to source to correct this.
Now, the fact that a lot of cheap TVs only have a 3.5mm headphone jack to “send on the sound” is annoying to me, too. A lot of people just don’t care about how things sound and therefore it’s not a commercial priority. Optical digital audio output would be ideal, in that cheap audio circuitry inside the television won’t degrade the sound being passed over HDMI and you can use your own choice of DAC, but they can be both expensive and add a bit of lag as well.
Wait, how is losing my independent speakers and having an audio setup not instantly compatible with my CD player, VCR, and my Victrola an upgrade?
You arent losing that unless you throw away all your cords. For most cases, less cords for same result is good.
Why would you lose that? It has the ability to carry sound but it doesn’t need to.
