Audio/Video Broke on Ubuntu 12.04

Those chrome GPUs don't do well under ubuntu. You will only get 2D acceleration at best

I'm still having problems with no sound card.

There is no hardware 3D acceleration for most VIA GPU's, so they use a generic CPU/software driver (which is slow, but better than no 3D accel at all). The software driver is llvmpipe and it was written by VMWare, so that part's correct.

As for your sound, the kernel module is missing/borked. I would recommend installing this .deb and rebooting: https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+files/alsa-hda-dkms_0.201212202005%7Eprecise1_all.deb

If audio still isn't working, run the alsa info script again and see if the !!Soundcards recognised by ALSA----------------------- section is no longer blank. If an audio card appears there, repost the updated alsa info.

I have sound before I log in, and had sound for a few minutes, and then it went silent when I reopened Rythembox.

This script visits the following commands/files to collect diagnostic
information about your ALSA installation and sound related hardware.

  dmesg
  lspci
  lsmod
  aplay
  amixer
  alsactl
  /proc/asound/
  /sys/class/sound/
  ~/.asoundrc (etc.)

See '/home/emerald/alsa-info.sh --help' for command line options.

Automatically upload ALSA information to www.alsa-project.org? [y/N] : y

Please inform the person helping you.

Hmm. My suggestion is to make a verbose pulseaudio log, and kill pulseaudio as soon as you lose sound (since it seems like your driver is okay now). I'm not good at reading them, but I will look at it.

Also, when the sound dies, look at the last lines of dmesg.
dmesg | tail -n 50

Kind of new to this. I've never had this kid of issue with Ubuntu
before. I'm still a noob. lol

Here is the Verbose log.

Looks like the attachment didn't carry though the mail. BTW The only thing I can get sound out of is Audacity. I can actaully select the sound card as output in it. The default sound has RTP Multicast and Simultaneous Output with no input.

Got it working for now. I was missing an ALSA mixer to control the sound
levels.

Sound is choppy at times, but I'm sure this is due to the graphics card and sound card both being integrated.
