Why do I have no sound when resuming from sleep, but if I plug in then remove headphones sound returns?

I am having strange issues with sound and volume with Ubuntu 11.10

I've noticed very often, especially when I get my computer out of sleep, it lacks sound even though the volume slider is cranked all the way up, but when I plug my headphones in and then take them out, it seems to kick start my sound back!

What gives?

What daemon in /etc/int.d needs to be restared with the restart command to fix this?

I have the following in my init.d folder

/etc/init.d/alsa-restore and /etc/init.d/alsa-store

Also, my start up Ubuntu sound doesn't play either....

11.10

    I had the same problem when I plug hadphone jack (in Ubuntu 11.10). I found pacmd command that show console

    $ pacmd
Welcome to PulseAudio! Use "help" for usage information.

    I run this

    >>> list-sinks

    and it returns that second sink (I have hdmi and analog stero) was mute

    muted: yes

    so I call (help will show all the commands).

    >>> set-sink-mute 1 false

    and it enabled the sound (before that I restarted puleaudio - $ sudo /etc/init.d/pulseaudio but I think it was not needed).

  2. The only thing that works so far is to killall pusleaudio and then restarting it back again. This seems to be an issue with Ubuntu 11.10 as I've had friends describe the same problem.
