Distorted output and high DSP usage in Ardour on Arch Linux

[thef1sherman]

Hi, I created this to install this plugin on Arch Linux (it's my first PKGBUILD!) and it looked like it was successful. I tried loading the plugin in Ardour and the GUI loaded, but the output was garbled. I'm not sure how to diagnose this and was hoping I could get some help with fixing this issue.

Sampling rates above 48khz cause problems. In particular, creepy artifacts and wheezing. Checked in cakewalk.

I have the same issue, also on 44.1 kHz. I'm on Fedora
