The problem: When I use X forwarding over SSH (ssh -X email@example.com), everything works in a local-looking window… except that Audacious remains silent.
The Solution: Audacious is confused about finding the PulseAudio plugin. I’m no coder, so I’ve got no idea why it’s the only thing that notices it isn’t entirely in Kansas anymore.
At any rate, right-click on the player and select Preferences, then under Audio, select a different Output plugin. OSS seems to work beautifully on my system.
Why would anyone want to do this? The next post, “Why My 5-Year-Old Loves SSH” explains it all.
