Comment 20 for bug 184314

I tried your recommendations twice, but it did not work for me. The first time, after I rebooted I noticed that the volume icon had a line through it. I figured my sound was muted so when I went to open the volume controls, it said that there was no device to control. I then opened up sound preferences and sure enough, there was nothing in the devices for me to pick from. Usually, ALSA and OSS were there, but there was nothing. After looking around, I got a notification to update, so I installed all of the checked packages that came up and rebooted and my computer went right back to having sound through the speaker and not through the headphones. I tried it a second time to make sure that I didn't skip anything, and the same thing happened, except I didn't get any notification to update. Right now I have no sound on my laptop and the volume icon has a line through it. Whenever I try to open it, it says, "No volume control GStreamer plugins and/or devices found." What should I do now?
