@zac Lennart Poettering, the same guy who made the Linux blight called systemd, that's what. The guy just doesn't know how to make decent programs.
@zac Maybe. For several years after its adoption by major distros, among the things pulseaudio couldn't do was mix sounds from different applications, things OSS, ALSA, & ESD had been doing reliably forever. Just as with bad systemd design decisions currently, Poettering's inclination was to blame everyone & everything else for not using his code properly.
@arielmt in my experience I had more issues with alsa playing from multiple sources than pulse :/
it's probably my overall inexperience talking, though
