Comment 7 for bug 662296

Yeah. I didn't realize I was telling you that, but that does seem like a fair assumption now that you say it. :)

Before recreating the bug, the output tab has one device in the list of available devices:

"Internal Audio Analog Stereo", which is also selected obviously.

[closing sound preferences dialog to recreate bug]

[recreating bug and reopening sound preferences dialog]

The same device as before is listed there now, and selected. The sound preferences dialog's slider, as mentioned, *does* work and correctly adjusts the volume.
