I think my sound not working is a hal/nohal issue. I just opened a 3.5.13-sru install with the in the exact same virtualbox environment and sound works beautifully. The only difference is that install loads hal and R14 doesn't. Have there been other sound problem with the nohal builds? I've attached my perirpherals-hardware-sound setup for review. It is the exact same between 3.5.13-sru and R14.
Start at the beginning. Find a wave file and test that the aplay command produces output. If not then run alsamixer.

On R14 I have the following sound packages installed:
libpulse 4.0-6 pulseaudio 4.0-6 pulseaudio-alsa 2-2
$ aplay /opt/trinity/share/sounds/KDE_Window_UnSticky.wav

This gets more interesting comparing the sound modules loaded in the 3513 install and the R14 install:
3513:
Module Size Used by snd_intel8x0 22768 2 snd_ac97_codec 89868 1 snd_intel8x0 ac97_bus 874 1 snd_ac97_codec snd_pcm 61237 2 snd_ac97_codec,snd_intel8x0 snd_page_alloc 5901 2 snd_intel8x0,snd_pcm snd_timer 14902 1 snd_pcm snd 44394 8 snd_ac97_codec,snd_intel8x0,snd_timer,snd_pcm soundcore 4378 1 snd
R14:

They are identical, so what ever is going on with R14, it has exactly the same modules loaded and available that 3.5.13 does, but for some reason it is not seeing the sound card or anything associated with it.

This seems to be an archlinux issue. root can see the sound system the user can't. Adding user to audio group makes no difference. I've posted to the Arch list.
