Hi, I'm a total newbie to linux and am also not very good with computers .
I recently did a full install of ubuntu 12.04 on my hp pavilion dv6700 which wasn't easy for a newbie like me due to the laptop having nvidia graphics (which I could see was a common problem)
...anyway, I did all the updates and evreything was fine (and also loving it over windows) for about a week, then I noticed the sound had stopped working, the icon was there but just no sound through speakers or headphones and also the wired internet connection was working sometimes and not others (same went for the wireless connection too).
I turned the laptop off and pulled the battery and power lead off, went back to it an hour later and everything was working fine again until an hour or so later I noticed the sound had stopped again (I hadn't restarted or downloaded anything).
This time I googled around for something to try in 'terminal' and after trying several things (which I dont really know what I was doing) then again using terminal it was saying 'sound card not detected' and in sound settings it had changed to dummy output.
So today I have done a full install from scratch again but still no sound and no sound card detected??
Any help would be great as I really don't want to go back to windows if I can help it.
Could you also keep any info I need as basic as possible so I can understand what I need to do.
Thankyou in advance!
