[Realtek ALC262, Green Line Out, Rear] No sound at all after upgrade to precise

[Brian Bolek]

Sounds worked in 11.10, don't work anymore after upgrade to 12.04. Apport tested ALSA to work and pulseaudio doesn't.

I was able to fix this by installing Realtek's Linux driver (3.0) at the bottom of this page:
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false
You have to tar -jxvf the bz2 file it downloads and run the ./install script, then reboot. You also have to unmute the master volumes again in your mixer - I had done this before and the install of the driver muted them again. After this, my sound worked in Linux and then worked in MythTV after a configuration change to tell the audio to use the new driver.
