This happened out of no where, but I have no audio. It's happened before and the only fix I could think of was to reflash.

Need this fixed as soon as possible, trying not to reflash, assuming that it's not a hardware issue cause it wasn't dropped or anything and this exact thing has happened before.

Also, when trying to play audio I get "Unsupported format". Don't know what happened this time, but last time it did this, there was an update to something gstreamer-related and I apt-get upgraded, upon a reboot, it happened. Not sure why this is doing it this time.

This same thing happened to me this morning. I had to change a setting in profiles then save, then reboot to get it back.
I am trying to remember what updates I did.
Sound is back now though.

what kind of settinng?

Although unlikely, you guys didn't happen to use my patches did you? It is found in this thread...Although I have removed for three days now.

This may related to one of the Power Kernel update that just got released. Unless someone can correct me?

Haven't applied the patches, and even after power kernel I had sound.

Ah thank you very much, so it seems that the problem is gstreamer, hope someone could guide you there, as I don't have it installed.

Try typing this comman into xterminal:
start pulseaudio

"sh: start not found"

Not an encouraging sign.

I just ran "pulseaudio", permission denied.

So I ran pulse-audio --system as root. Got a lot of garbage but what stood out was Unable to connect to D-Bus.

Edit: I don't really have the time to troubleshoot random linux issues, I get enough of those on my notebook. I'm just gonna reflash it. Thanks for the effort though.

Did you try running:

start pulseaudio

as root too?

I ask because it's the only way you could have permission denied.
