Ardour keeps telling me my hard drive isn't fast enough for playback. I'm using a Thinkpad t420 with an SSD, so the only reason I can think that my hard drive wouldn't be fast enough is if swap is slowing it down. I wanted to record music over winter break but I couldn't because of that issue. Music in Linux is frustrating. I will say that antergos made the process of installing jack, guitarix, rakarrack, and ardour a breeze though, so that's something.
