+<p>About a month ago I took a long afternoon being like "Okay whatever let's see how deep the rabbit hole of linux audio playback goes" (<a href="https://queer.hacktivis.me/objects/33fc99e9-c901-4764-8b75-27d78bf7cc7d">previously</a>, <a href="https://queer.hacktivis.me/objects/3a5e4919-e8ee-4e4c-b50c-899f4afac678">previously</a>). That was a mistake I guess but let's at least avoid others from doing the same and so share what I did as it's fairly complete (patches with reference/citations welcome btw).</p>
