On Ubuntu 12.10 "Quantal Quetzal" and later you will no longer be able to use the proprietary fglrx driver on your Radeon HD 4850/4870 as AMD have dropped support for this card in their drivers around the same time that they added support to their drivers for the newer kernel and xserver used in Quantal.
You will be able to use the open-source radeon driver, but note that HDMI audio on AMD/ATI GPUs has been disabled by the upstream kernel developers as it causes blank screens on a lot of systems. You can re-enable HDMI audio by adding radeon.audio=1 to your GRUB kernel boot options as described at https://help.ubuntu.com/community/Grub2/Troubleshooting#Editing_the_GRUB_2_Menu_During_Boot -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/970795 Title: [MSI 785GM-E51 (MS-7596), ATI R6xx HDMI, Digital Out, HDMI] No sound at all Status in “fglrx-installer” package in Ubuntu: Confirmed Bug description: sudo lshw -class multimedia *-multimedia description: Audio device product: RV770 HDMI Audio [Radeon HD 4850/4870] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0.1 bus info: pci@0000:01:00.1 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list configuration: driver=snd_hda_intel latency=0 resources: irq:43 memory:feaec000-feaeffff *-multimedia description: Audio device product: SBx00 Azalia (Intel HDA) vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 14.2 bus info: pci@0000:00:14.2 version: 00 width: 64 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: driver=snd_hda_intel latency=64 resources: irq:16 memory:fe9f4000-fe9f7fff ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-21.34-generic 3.2.13 Uname: Linux 3.2.0-21-generic i686 NonfreeKernelModules: fglrx AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
