I cant believe the problems I have had. I have an intel DH77EB with a core i7 HD4000 chip.
My goal is to start off with Base Ubuntu as I want this pc to host XBMC plus be a Myth TV backend.
I have tried Ubuntu 12.04, 12.10, every kernel at
http://kernel.ubuntu.com/~kernel-ppa/mainline/ For both versions.
and I have tried the latest XBMCbuntu.
12.04 base makes solid black color have a green tint.
upgrading the kernel fixes that, but then I loose 24Hz capability.
I can not get DTS-HD MA to work even though all bugs are supposed to be patched in kernel 3.7 and 3.8/
12.10 better support out of the box but I can not get DTS-HD MA to work even though all bugs are supposed to be patched in kernel 3.7 and 3.8/
I loose 24Hz capability.
MythTV isn't great.
I want Ubuntu 12.04 with Frodo, DTS-HD MA and 1080p 24hz and 60hz working properly.
If anyone can help that would be great. Someone else out there must have this setup working with linux. Everyone that I have seen successful is using Windows 7.
Thanks.
Thanks for the reply but I have read up on that issue and it has gotten me no where. i have updated alsa and even built the kernel on my own and not had luck. also the patches are supposed to be in the main repos right now and a part of all 3.7 kernels and are not.
I dont know why it isnt in any of the ubuntu mainline kernel and an option isnt present that doesnt require people to compile stuff.
when you say 3.5 and 3.7 do yo mean that you applied the base 3.7 kernel from the ubuntu mainline or was it another variant (3.7.2 or another place)
I got around to trying the latest current in your post. It is a 3.8 kernel. I know it had an impact on the video driver because the Green blacks issue of default ubuntu 12.04 goes away, but xbmc fails when it tries to switch to 24hz and it eventually goes back to the default 60hz.
Audio is still the same. A DTS-HA MA stream turns into horrible multichannel output noises.
Interestingly enough the latest XBMCbuntu with a 3.5 kernel worked in 24Hz mode however it still suffered from the Green blacks issue. It also gave me an option to set that in the Video settings which I don't have now. Is this possibly a Unity issue, and I should try using Gnome? I have no loyalty. Not sure how XBMC interacts with the different desktops.
More interestingly, 24 Hz mode works if I enter XBMC from the login menu. It does not work if I am in Unity or Unity 2D.
I would like it to work from Unity.
Bitstreaming doesn't work from either of them.
I've been trying to get this working on my Sandy Bridge setup. It seems like the people at openelec have made some progress recently.

Basically, try the
http://sources.openelec.tv/tmp/image/Ope...61.tar.bz2 build, and then SSH in and do this.
Quote:read and understand the following, and place it in a file called 'disable-spdif-for-hd-audio.conf'
in .config/modprobe.d/
Code:
# Uncomment the following lines to disable any S/PDIF out to deliver
# bitstreamed audio on Intel builds. This is a rough workaround for
# users that have both S/PDIF and HDMI audio outputs on their motherboard
# or motherboard+discrete graphics combo.
# EVEN IF YOU ARE NOT USING THE S/PDIF OUTPUT
# but still have one, you will need to uncomment the lines below !
# after uncommenting these lines, you must reboot for these settings to take effect
# blacklist snd_hda_codec_realtek
# blacklist snd_hda_codec_sigmatel
# blacklist snd_hda_codec_cirrus
I haven't had complete success with this (still get popping noises with DTS-HD MA 7.1) , but others have. Hope this helps!
Thanks for the advice, but I need this to work with an ubuntu install. Preferably stock 12.04 as a base, but I have no love for Unity. This machine is going to run MythTV as well as XBMC. I think just xbmc on a core i7 is overkill.
I have done a couple of tweaks (such as add legacy full screen support in CompizConfig) but no such luck. Occasionally I will get 24hz to activate from within Unity however the screen goes blank and I loose mouse and keyboard.
The intel nightly kernels that ubuntu supports are slowly getting there with adding HDMI and intel fixes.
I am going to see if I can disable SPDIF from the bios and see if that helps.
i tried xbmc with the detect refesh rate amd unredirect toggled in compiz config and that didnt work either.
the only other thing i touch in compizconfig is legacy full screen support for mythtv
All visual effects in compiz must be off.

does that include window decoration?
Everything Turn it off completely. and then must add composite fix.
For NVIDIA-Graphics use Disable composite in xorg.conf, like so:
Code:
Section "Extensions"
Option "Composite" "Disable"
EndSection
Or in terminal
Code:
sudo nvidia-xconfig --no-composite

Holy crap. I got dts-hda ma and it worked!!!
the main problem was that people referred me to Xingchao's kernel patches. No where to be found was this nugget in the bugzilla comments previous to Xingchao's fix.

I am going to do a clean 12.04 install tomorrow with xubuntu (no 24Hz issues aka no compiz) and update to the latest current intel-drm branch. that plus the fix above should get me a sweet mythbox + xbmc frontend.
I plan on documenting my steps to share.
