When playing music via ogg123, mpg123, juk, or rhythmbox (all tested), sound starts repeating frames (a stuttered echo) after switching ttys from X. This continues until the application and all support programs in question (for juk, all of the KDE support programs, for mpg123 and ogg123 just the program, for rhythmbox, might even need to restart dbus, along with all gnome helpers). How-To-Repeat: Start X, start playing audio, then switch ttys.
Additional info -- Using the Snapper driver.
My most recent observations today seem to indicate that all programs with any part of the device open (dsp, mixer) must be closed before the stuttering stops.

Closing as this is no longer the case.
