Default Which Nvidia IGPs support 7.1 channel LPCM under Linux?


I am planning to build a linux workstation or two that have both advanced scientific computing (via CUDA and Stream) as well as multimedia/HTPC/gaming capabilities. Towards that end, for starters, I am trying to figure out (with some certitude) as to which of Nvidia's IGPs listed below (taken from this HTPC building guide) are fully supported under linux, including working 7.1 channel LPCM audio over HDMI:
- GeForce 8200 & 8300, nForce 750a & 780a SLI mGPU for AMD
- GeForce 9300 & 9400 mGPU for Intel
Looking at the installation guide for the latest 180.37 release under the supported GPU section, we have these AMD chipsets as being supported by the current driver:

GeForce 8300 0x0848
GeForce 8200 0x0849
nForce 730a 0x084A
GeForce 8200 0x084B
nForce 780a SLI 0x084C
nForce 750a SLI 0x084D
But, does support here mean that they are fully supported, i.e. including 7.1 channel LPCM over HDMI audio?

On the Intel side, when one searches for 9300 and 9400 in that list, these entries come up:
GeForce 9400 GT 0x042C
GeForce 9300M G 0x042E
GeForce 9300 GE 0x06E0
GeForce 9300 GS 0x06E1
GeForce 9300M GS 0x06E5
GeForce 9300M GS 0x06E9
GeForce 9400M G 0x0862
GeForce 9400M 0x0863
none of which seem to be the 9300/9400 chipset IGPs. Does this mean that those IGPs are NOT supported by the current linux driver (and if so, is support planned in a (near term) future version of the linux driver?) Thanks in advance for help, tips and pointers.
