Subject: Re: How to direct audio output
Every DE makes a sound applet of some sort to control levels, I just find
most suck, or are at least diminished from pavucontrol in the name of
trying to make it "simple". Sometimes we need beyond simple.

30-40gb of memory if I wasn't watching it. Why, I never really did find
out, but killing it tended to keep it in check. I haven't seen this in a
bit though, so figure someone noticed the memory leak at some point, by

Glad this helped!
