AMD fglrx Driver Limitations

The AMD fglrx drivers on Linux limit the number of real audio channels to 2.0, this only provides enough bandwidth for LPCM 2.0, DTS (5.1) and AC3 (5.1) and so HD audio is NOT possible on Linux for AMD GPU's and that "Output stereo to all speakers" must be disabled. Further to this the lglrx drivers limit HDMI audio to a 48Khz sample rate however 96KHz is possible on SPDIF.

When using AMD HDMI to an AVR then use the "AVR (no HD Audio)" settings.

Intel HD Audio

HD Audio on Intel SandyBridge & IvyBridge systems require a patch from Intel to be included within the kernel, Linux 3.7 and higher include this patch as standard. In addition modification to system files maybe required in order to get the HDMI audio working.

For more detail on the required Linux modifications see Intel Linux Modifications for HD Audio
