Hi,
My question eventually boils down to: Does anybody definitely have multichannel LPCM working over HDMI from the Acer Revo?
Long version:
I've been trying to get the Revo to output multichannel LPCM to my Sony STR DH800 amp over HDMI. Stereo is fine, and it even outputs DTS and DD 5.1 fine if I select the "DTS/DD capable decoder" options in the sound config. But I have a large number of .mkv files with multichannel flac audio, and what ever I do, I cannot get any more than stereo to work in LPCM. This means I don't have the centre channel.
I've read these threads with interest:

Trying to get my setup as close as possible to other apparently known working setups, I
* Installed a fresh Jaunty 9.04
* Downloaded the Alsa upgrade script from http://ubuntuforums.org/showthread.php?p...ost6589810 and installed Alsa 1.0.21 [Alsa has the 8 channel nvhdmi fix in it already, so I didn't need to patch the Alsa code]
* Ran speaker-test -Dhdmi -c6
I get audio from left and right, but nothing from centre, or any other speakers. The amp doesn't appear to indicate that it's receiving input from other channels, but I've only just got the amp, so am somewhat unfamiliar with it.
According to other posts I think it should be working at this point, but it isn't. If anybody can shed any light on this I'd be grateful.
Other things I've tried are:
Upgrading the BIOS on the revo from the A1 to A2 version
The Karmic beta
But nothing seems to work.
Cheers
