It doesn't appear any mobo/sound chip will pass 8 channel PCM in Linux- yet. I suspect once the DD+/DD-HD and DTS-HD decoders are working well in Linux, the sound drivers will be updated to output PCM. My guess is about 8-12 months. Some motherboard/sound chips do support SPDIF-level passtrhough on HDMI, which means up to 2 channel 24/96 PCM and DD/DTS bitstreams over HDMI: see for discussion and confirmation of SPDIF-over-HDMI output from member mythmaster. I personally can't hear any difference between DD/DTS and DD+/DTS-HD, and the audiophiles I know are 2 channel purists, so 2 ch 24/96 PCM is fine for me.

I personally can't hear any difference between DD/DTS and DD+/DTS-HD, and the audiophiles I know are 2 channel purists, so 2 ch 24/96 PCM is fine for me I know that 2 channel PCM is working under ALSA. Under Windows Multichannel PCM is working since quite a while. MOBOs and GPUs supporting it are at least available since 6 month by now, right? Even AMPs are out there supporting it.
Would be nice to see the roadmap of ALSA development related to multichannel PCM. It appears the ALSA people are working on it- 'Are we sure that there is supposed to be support in the driver for audio over HDMI with NVIDIA nforce chipsets?
That is, is this a missing feature in the current drivers or broken code? Grepping the driver source from Realtek's site reveals references to HDMI for ATI chipsets, but nothing for nforce chipsets.' 'I found in the NVidia forums where it has been asked and the answer is that audio over HDMI is NOT currently supported in the NVidia Linux drivers and it may be supported sometime in the future.
' 'FYI, there has been a bug reported in the ALSA bugtracking system for this issue, and it actually references this bug for ubuntu. In the ALSA system it has been assigned and is currently listed as a major bug in version 1.0.15 of the driver, but there hasn't been any updates since 11-2-07.' 'Possible solution: I used to make work my HDMI audio by doing this: Open the mixer ans select 'Realtek ALC833 (OSS Mixer)' as the device. Edit / Preferences. Check 'Digital-1' and select Close.
In the Recording tab, ajust the volume of the Digital-1 to the preferred level. Your HDMI audio should now work. My understanding is that the 'SPDIF' digital output is the one that's used under HDMI, but this output gets classified in the recording / input class (bug?).' Also from Nvidia re: SPDIF over HDMI 'We recently implemented support for audio through HDMI and it is expected to ship in the release 177 driver when available.
I suggest you periodically check our web site for driver updates to version 177.'
