(Apologies - also posted in the E7AUM-DS2H thread in the main HTPC forum)

I've been running my E7AUM-DS2H with Vista HP 32 bit and then Win 7 Beta and RC 32 bit for the last 6+ months with no major problems.

I've just installed Ubuntu 32bit 9.4 onto a spare hard drive in the same rig and am having all sorts of problems with the nVidia drivers. Firefox crashes when maximised to full-screen, and I get all sorts of freezes and corrupted graphics.

I'm running 4GB of Corsair PC6400 RAM as 2x2GB sticks in dual channel, and have allocated 512GB of RAM to the frame buffer.

Anyone else had problems ?

Thanks.

My suggestion would be, try running a memory test (http://www.linuxtech.net/tips+tricks/hw_diagnostics-pt1.html), I have seen cases where Windows didn't show up existing memory errors while Linux did.

Also you could try some other Linux distro (use a Live CD so you don't have to install anything), some particular versions of some distros sometimes don't work well with specific hardware, while others do.

My suggestion would be Mandriva One Live CD (http://www.mandriva.com/en/download/free), but any will do really for testing purposes.

With ref. to memory test I added new ram to a system and only ran into problems when I ran mythcommflag. Memtest86 passed the memory, but it was still the problem. The default voltage for this particular ram was 1.95v and the bios had it at 1.85v. Raised it to 1.90v and haven't had a problem since.

Well it appeared to be the nVidia 180 drivers I'd installed which were offered by Ubuntu as part of the "Restricted Hardware Drivers" option...

Re-installing from scratch and installing the nVidia 185 drivers has been rock solid. Took a little bit of research to get HDMI audio working (PCM2.0 and SPDIF only so far - need to spend some time working on multichannel PCM) and optimise de-interlacing in XBMC - however I'm pretty happy with the set-up for a couple of hours work.

Nice XBMC touch is that it reads the XML files that MyMovies created in Windows and which are stored on my server - so all my DVDs appeared in the XBMC library with the right artwork and metadata!

Very impressed so far.

Do you get DD and DTS 5.1 discrete channels output from this mobo? either thru HDMI or preferably thru analog or SPDIF?

Thank you.

I've got Ubuntu 9.04 32bit + XBMC SVN PPA + nVidia 185 drivers playing DVDs with DD and DTS being bitstream output as DD/DTS streams via HDMI for my amp to decode. MP3s and MP2 audio is output as PCM2.0. I haven't looked at optical/coax SPDIF output as I have no use for it - my set-up is primarily HDMI.

I haven't ventured into Linux's handling of multichannel PCM via HDMI yet - so am not decoding DD/DTS in the PC.
