Stereo audio channels swapped?
Hasturtium:
In most distros there's a way to solve this by copying the /etc/pulse/default.pa file to ~/.pulse/default.pa, then appending these lines to the end of that file:
--- Code: ---load-module module-remap-sink sink_name=reverse-stereo master=0 channels=2 master_channel_map=front-right,front-left channel_map=front-left,front-right
set-default-sink reverse-stereo
--- End code ---
Save, exit, and execute pactl exit at the terminal to force PulseAudio to restart and enact the changes. You may need to change the master= value if the system default audio device isn't the Blackbird's built-in audio, but this worked without much hassle in Void. I am currently trying to determine the appropriate procedure for Fedora... Red Hat does things a bit differently than I'm used to. That's not bad - I just have to wrap my head around it.

If this fixes the problem, then this is worth an entry on the wiki.

All I needed to do was add
--- Code: ---load-module module-alsa-sink device=hw:"ICUSBAUDIO7D" channel_map=right,left
--- End code ---
in the existing /etc/pulse/default.pa
