having a bit of an issue with getting audio to go through HDMI. Here are the base specs:

OS: Ubuntu Desktop 12.04.1 x64 CPU: AMD A10-5800K 3.8G 4M FM2 R Mobo: MSI FM2-A75MA-E35 OS: Ubuntu 12.04.1 LTS Vid Card: (integrated on CPU) AMD Radeon HD 7660D

HDMI sound works fine under Win7 (after mobo and vid drivers are installed), so it's not physically broken. Audio through the normal headphone jacks works fine under Ubuntu.

Looking at the audio panel, there is no HDMI output at all. aplay -l also reports only:

card 0: Generic [HD-Audio Generic], device 0: ALC887-VD Analog [ALC887-VD Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

In additional drivers there are two versions:

ATI/AMD PROPRIETARY FGLRX GRAPHICS DRIVER
ATI/AMD PROPRIETARY FGLRX GRAPHICS DRIVER (post-release update)

The first installs, but problem persists. I do get more resolutions to pick from. Second version does not, reporting it failed installation and to find details at: /var/log/jockey.log

Looked at the log, and it's insanely long, if necessary I can get it to you guys.

Did more research and some had luck by manually installing the drivers, so tried to give that a shot by following this:

https://help.ubuntu.com/community/BinaryDriverHowto/ATI#Manually_installing_Catalyst_12.6

starting at 3.1 Manually installing Catalyst 12.6. I immediately had 2 issues, (1) the AMD website does not provide any drivers for Linux, and (2) the following command did not work:

sudo sh amd-driver-installer-12-6-x86.x86_64.run --buildpkg Ubuntu/precise

sh: 0: Can't open amd-driver-installer-12-6-x86.x86_64.run

Some other posts stated to update "alsa-drivers", but that also did not work as install command for the new version of them did not work. I forget the exact issue, but similar to above, cannot open / cannot find.

Any help would be greatly appreciated!
