Hi, I have the same problem on an ATI HD3850.
The videos from youtube are fast but unlike Melissa I have the audio since I deleted the folder ".pulse" in my home directory.
I have the following versions:
alsa-base - 1.0.24
pulseaudio - 1:1.0-0

This problem occures for me only when the audio output is set to HDMI. when the audio output is set to anaogic everything works smoothly.

Yes, my problem is the audio on the hdmi channel.

I see the same issue on 12.10 quantal, switching from hdmi audio to analog fixes it.

the headphones do not work

i was able to fix this by googling for my brand / model of laptop and 'ubuntu'

ubuntu hp dv6 sound

there are numerous forums that list procedures to fix, typically by editing /etc files

i did several of them and now it works.

this was added to /etc/modprobe.d/alsa-base.conf

     alias snd-card-0 snd-hda-intel
     alias snd-slot-0 snd-hda-intel
     options snd-hda-intel model=dell-m4-3 enable_msi=1

and this was edited into /etc/pulse/ (replacing the old udev line)

load-module module-udev-detect tsched=0

it does NOT work

when i close my laptop lid and reopen, the sound is not there.

also the little speaker icon in the menu is gone.

do you mean you close laptop lid while the sound is playing ?

you have to provide alsa-info before closing the lid and after reopen the lid

I fixed it by reseting PulseAudio

 $ rm -r ~/.config/pulse; pulseaudio -k

rythmbox, youtube, i dont know why or how, but it works again!

For a more simplistic approach Ubuntu 14 has the pulseaudio volume control that allowed me to switch the audio back to analog from hdmi fixing the issue without the command script.
