so today I played a 3 second long mono MP3 track in foobar(some old piece of a sound with absolutely nothing special about it, it's something I used to have as a sound alert on IRC ages ago(well IRC ago), and it pretty much broke audio on my computer.
after some half backed diagnostic, I noticed that ASIO was still fine, but DS and wasapi were dead. foobar would give me some unknwon error number, youtube had no sound etc. reboot did nothing to help, windozzzz 10 diagnostic saw nothing, unplugging/replugging the USB DACs didn't help. it felt like this time I really had messed up(well I have a complete hard drive image just about a month old so I didn't start crying just yet).
in the end I got Direct Sound and WASAPI back by disabling my devices and enabling them back. somehow they came back ON with the wrong/not my usual settings??? the order of my devices is different so now my virtual cable for headphone DSPs is set to the wrong output. my shortcuts to switch DACs are wrong, same for Room Eq Wizard and other audio apps. a really effective waste of my time.
I looked up everything and I believe I'm back to traditional configuration, but I had no idea a track could initiate such a mess. even less so when it's 3second long. if magic is science we don't understand yet, then I just witnessed magic ^_^.
