Technically, DOS doesn't support those features. The program running on DOS can though. eg sound chips during the DOS days. Each game had its own audio driver for each chip. No OS support whatsoever. Looking back, it was rather insane: instead of programming to a standard audio interface provided by an OS, each game had to deal not only with its own audio interface, but drive the audio hardware directly. The same could be said for video, although video was quite a bit easier to deal with.
