st does not play at all. The 'test' buttons don't even light up to show they are trying to play a sound.
I have checked alsamixer on the CLI and disabled the automute, also checked that all volumes are up there on all sound cards detected.
I have tried installing the packages from daily build alsa HDA (http://ppa.launchpad.net/ubuntu-audio-dev/alsa-daily/ubuntu/pool/main/o/oem-audio-hda-daily-dkms/) but am unsure which one to choose (i've tried raring so far).
Also i have totally removed pulseaudio and it's packages, and alsa and it's packages and re-installed them all using apt-get.
the output of lsmod |grep sound :

In the sound manager (i'm using Mint 15 cinnamon), I can see HDMI / Display port (GK107 HDMI Audio Controller)
HDMI / DisplayPort (Built-in Audio) and
Speakers (Built-in Audio)
I have volume controls, the function volume controls on the keyboard work, everything 'looks' like it's working but there is no sound in any application or system sounds at all.
The system i am using is an Alienware m14x R2 (it does use Nvidia Optimus) - I have not installed bumblebee as yet. This is a fresh install with no changes other than updates and the procedures I have tried above.
I have edited the alsa-base.conf multiple times with different specs (PCH / generic / dell / and so on).
Funny thing, I tried ubuntu, it worked with sound but wouldn't load X because of some problem with the graphics setup, so i loaded sabyon and it worked but had problems with broken dependencies (which i just couldn't resolve), so i tried fedora, it worked but had issues with steam / games so it hought mint was a happy medium being buntu based should work with steam well etc, but now it has problems with the sound....
So i'm a bit frustrated with it all at the moment, it's been days on end of googling things, installing uninstalling / changing distros etc... I'm just after something that I can install , will use the hardware i have, and go from there. I don't mind playing with things like huawei modems / sd slots etc, those things I expect to be tricky, but simple things like display driver / sound driver / HDD read write / SAMBA... would be nice if just one distro could install without problems
anyway, /rant. Any help would be appreciated because i really don't want to go through another session of distro swapping.
