I can indeed confirm that upgrading to AMD Catalyst 12.6 Beta fixed the problem.
I build the .deb package from the install file using the internal build process: sh ./amd-driver-installer-8.98-x86.x86_64.run --buildpkg Ubuntu/precise sudo dpkg --install fglrx_8.980-0ubuntu1_amd64.deb sudo dpkg --install fglrx-amdcccle_8.980-0ubuntu1_amd64.deb After restart, the problem no longer occurs. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1001842 Title: No Audio from HDMI After Switching Monitor Off / On To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1001842/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
