Getting started with LMDE "4" post 2 - Pulse, Alsa, Nouveau and Nvidia

Sound and Video

Everything is pretty much working now but I have no sound. I am now using a  Gigabyte G41MT-s2PT Motherboard so I guess Intel HD has an issue.

Pulse Audio vs Alsa

aplay -l

Remove Pulse

The card exists so I guess it is Pulse giving me hassle. Time for Pulse to die! (This is optional - If Pulse works for you then you can leave it alone)
sudo apt-get purge pulseaudio pulseaudio-utils gstreamer0.10-pulseaudio libpulse-browse0 paman pavumeter pavucontrol
This file needs to be removed if you use skype etc.
sudo rm /etc/asound.conf
Add this:
sudo apt-get install libalsaplayer0
Removing Pulse is a hiding for nothing. I had to re-install Pulse after getting this message and pulling my hair out.

The audio device "default" could not be used linux

Activated the Nvidia Driver

Did a dumb thing I think. I have a new Sanyo CG20 that was on special with a second battery and 8GB SD card for RM600 so I did a few test videos and it was jerky with many artifacts. It was 1920 x 1080 at 60fps. I immediately (prematurely) blamed the Nouveau drivers and installed the Nvidia drivers. Up to that point the Nouveau drivers seemed pretty good.

sudo apt-get install nvidia-kernel-dkms nvidia-glx build-essential nvidia-settings nvidia-xconfig
sudo apt-get install nvidia-settings
sudo nvidia-xconfig
Hmmmm, OK for a while there I had a very unstable machine. Whenever I played a video Cinnamon would crash. I could sign in to MATE and if I removed  ~/home/rayd/.local/share/recently-used.xbel I could restart Cinnamon till the next time I started a video. Loop.

I have no idea how I fixed it but what I did was re-install VLC, totem and gstreamer.

All seems ok now.

Snotkop is bopping on the second monitor and Asla is rocking the room. I can do with castle now and some biltong.
