He has an Asus PC with a Sapphire Radion HD 6000 sound card. The card is showing in the sound preferences and I have ensured that nothing is muted but no sound. I have had a look on the forum and tried some changes that have been mentioned but no difference, still no sound.
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get update
sudo apt-get install fglrx-amdcccle-updates
sudo aticonfig --initial
sudo aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0
you will need to be root for the following.
you have to edit your grub config. open /etc/default/grub with your preferred text editor and look for GRUB_CMDLINE_LINUX_DEFAULT and add radeon.audio=1 to the end of it.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"
now save the file and run update-grub
