It's only a problem if you need very low latency. This system doesn't, so you can just set a massive interface buffer size. Scheduling is a complete non-issue if you have several seconds worth of output buffer.

When professional audio people talk about the difficulties of glitch-free playback, they're talking about running their CPU at near 100% utilisation with 64 or 128 samples of buffer. Playing back a clean and glitch-free audio stream is trivial and has been for years.
