Reinstalled Arch, currently running XFCE4, I had a Gnome 3 DE before and everything worked fine.
So I installed ALSA (and Pulseaudio) and followed the instructions in the wiki, but when I run speaker-test -c 2 I get this:
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,
So I run alsamixer, and the default soundcard is the Nvidia one from my GTX card. Obviously the wrong one.
But in /etc/modprobe.d/alsa-base.conf Ive already set the cards up (I think). It looks like this:
options snd_usb_audio index=0
options snd_hda_intel index=-2
My motherboard has no onboard audio so I should only have two possible soundcards. As you can see I'm trying to exclude the Nvidia one, and after setting this file up is when VLC started working.
But still, whenever I start up alsamixer I get the same thing, 3 options:
Default: HDA Nvidia
0: USB PnP Sound Device
1: HDA Nvidia
I'm thinking this has to be the issue somehow.
I can set them both up in the audio mixer, and the settings of the volume control, but it makes no difference. No sound in youtube, no sound Vimeo, no sound in mplayer. VLC = no problem.

Not an expert here, but since you have installed pulseaudio, I think you have to follow the pulseaudio wiki.
With pulseaudio, you can setup inputs and outputs with programs like pavucontrol.
On the other hand, you can remove pulseaudio if you don't use it.

vlc didn't work before I installed Pulseaudio. But ok, thanks I ll look at it.
