I can see how I wasn't clear. This issue isn't that sound is coming out of both devices; it is that once I select "Digital Output (S/PDIF) USB Device" (under the "Output" tab of the "Sound" preferences dialog), the sound continues to be played through my internal speakers AND no sound comes out of the ArtDio NB- 005B USB Speakers (for which my selection specifies).
Again, this behavior started after upgrading to Ubuntu 12.10 beta 2, but worked correctly in 12.04. When I run alsamixer, it says │ Card: USB Device 0x46d:0x821 F1: Help │ │ Chip: USB Mixer F2: System information │ │ View: F3:[Playback] F4: Capture F5: All F6: Select sound card │ │ Item: Esc: Exit │ │ │ │ │ │ │ │ This sound device does not have any playback controls. ---------------------------------------------------------------- Actually, that's probably not the right device.
