"Finger duct" is often the easiest way to get relatively clean results in a situation like AV where cabling is sort of poorly standardized (connections front and back, inline DC supplies, etc). It's fairly cheap and often run vertically on rack posts and horizontally above and below cable-dense areas like patch panels and switches, but in an AV situation you probably only need one vertical channel to get a big improvement in results. Finger duct can get pretty messy without planning but I think it's usually the best results to effort ratio.
