HDMI AUDIO a Success finally - rodercot - 2008-12-15 23:27
Hey ALL,
So I finally have 1080P video and HDMI audio on my ASUS M3N78-VM and the Asus P5N7A-VM (as of this evening)
Asus M3N78-VM bios version 0507 int. and ext. codec selected and HDMI audio out.
Asus P5N7A-VM - shipped bios (actually I did not even look at the rev) bios codec - Auto, HDMI Output
It is a bit tricky BECAUSE Alsa 1.0.18a driver will not compile on 2.6.24 with --all-cards options and you need this.
I also dwnlded and installed the NVIDIA 180.11 driver from the ftp site do a search for it and you will find it.
OK.. here is how I did this.
On a clean install to hard drive with XBMC Live 8.10 - from desktop
ctl-alt-f2
Login - xbmc
password - xbmc or whatever you used at install
sudo apt-get update - let it run
sudo apt-get install wget - let it install
sudo apt-get install build-essential linux-headers-`uname -r` - let it install saying Y or N when required.
download the NVIDIA driver
wget ftp://download.nvidia.com/XFree86/Linux-x86/180.11/NVIDIA-Linux-x86-180.11-pkg1.run
now install the NVIDIA driver
sudo telinit 1
cd /home/xbmc
sudo sh NVIDIA-Linux-x86-180.11-pkg1.run
say no to the first question then yes to the rest.
Now sudo reboot - your driver is installed
now the fun stuff with alsa update.
go here and download the latest script.
keep the page open for reference.
http://ubuntuforums.org/showthread.php?t=962695 - it is rev 1.14
**UPDATE** to save having to run this script twice do this step here first**
copy the script to your /home/xbmc directory from an ftp client or the like then
cd /home/xbmc
tar xvf AlsaUpgrade-1.0.x-rev-1.14.tar
sudo ./AlsaUpgrade-1.0.x-rev-1.14.sh -d
(This will download all the alsa 1.0.18 files to your /usr/src directory and create the required Alsa directories for you.)
sudo reboot
after boot - ctl-alt-f2 and login again
now go here and dwnld the snapshot - if the link does not work you can get it from this page as well.
ftp://ftp.kernel.org/pub/linux/kerne...napshot.tar.gz
http://ubuntuforums.org/showpost.php?p=6249579&postcount=65
once you have that file on your windows machine. ftp in to your XBMC Live machine and copy it into your
/home/xbmc directory
now do these steps on your XBMC machine via putty or on the console
Code:
cd /home/xbmc
sudo tar xvvf alsa-driver-snapshot.tar.gz
cd alsa-driver
sudo ./configure --with-cards=all --with-card-options=all --with-sequencer=yes --with-oss=yes --prefix=/usr
sudo makewhen completed do this.
Code:
cd alsa-driver (if you are not already in this directory)
sudo cp -rf * /usr/src/Alsa-1.0.18a/alsa-driver-1.0.18aNOW once that is completed
cd /usr/src/Alsa-1.0.18a
cd alsa-lib-1.0.18
sudo ./configure
sudo make
sudo make install
cd ..
cd alsa-utils-1.0.18
sudo ./configure
sudo make
sudo make install
cd /home/xbmc
now you can run the script
sudo ./AlsaUpgrade-1.0.x-rev-1.14.sh -i
Note the (-i)
This will install the latest 1.0.18a version of alsa for you.
I had to do this a couple times to get it to take.
sudo reboot
after the reboot you can go back to your shell login and run alsamixer - you should now have either an HDA NVIDIA MCP78 HDMI (generic 10de) or a HDA NVIDIA MCP7A HDMI (generic10de) and the alsmixer version should be 1.0.18. If this is not the case the install did not take and you will have to run the script with the -i again.
Once this is all done and the desktop is up and running
go into settings-system-audio and change the passthrough device to hdmi from default or iec958 whatever it is now. Do not forget to change your bios from SPDIF to HDMI output.
This has taken me nearly two weeks to get sorted out.
I have tested Everything.
2 channel Stereo
Mono
Dolby Digital & (Plus)
DTS & (HD)
2 channel Pcm
DVD playback
Music sources MP3 and FLAC.
The only thing I do not have is navigation sound but I usually turn that off anyhow. I have not tested the Spdif output and I am not going to, this is working and I am leaving it alone.
PLEASE back up your userdata info first in case something goes wrong. Mine worked but I cannot be sure all will and also if you have the latest Nvidia driver and alsa version installed then just try changing your passthrough device setting to hdmi.
hope this helps, it has been a while, I got this board in like may of this year.
rgds,
Dave

how about multichannel flac or Dolby TrueHD? I assume it will pass multichannel FLAC as 6/8-ch PCM

Matt,
I do not have any mult-channel flac stuff encoded to try, I tried a couple Re-authored BD discs that I encoded with DTS-HD and they were fine so I would assume that Dolby is the same I am not sure if I have any with a trueHD track I think that I converted them all the std 640 ac3 when I did my HD-DVD's but I will check and let you know.

UPDATE to this,
I had to change both items under settings-system-audio to hdmi. I had a couple of files that would not play. Nothing in alsamixer would do anything.
I do have now under alsmixer an iec958 switch as well as pcm they seem to make no difference and the device is now actually NVIDIA MCP78 HDMI instead of VIA VT1708B Analog.

180.11xx NVIDIA drivers are still sort of beta yes? Will this work as well with 177.xx drivers? I am trying to get this working on a different ASUS board and was trying to stay away from the new accelerated drivers until they were more fully baked so am curious

well I did try this with 177.82 as well and could not seem to get the card to change from VT1708b to Nvidia HDA MCP78 HDMI. If you have 177.82 and alsa 1.0.18a installed you can try to just change the output in audio settings to read hdmi and try it. Remember to change your settings in your bios. I think your board uses just the alc88x or is it alc12xx chipset. I am not sure if the bios settings are the same as mine.
I did read a few posts from google searches that say they have had it working with 177.82.
I got this running first on a full Ubuntu 8.10 install with I think 177.82, the 177.80 driver that comes vanilla will not work. With a full version Ubunutu install I had to go into system - preferences - sound and change the defaults to the hdmi device and then I got test noise but could still not get output with vlc or gzine or Ubuntu itself, but XBMC output it fine on HDMI via the change in audio preferences.
I will say the new beta driver seems to be OK. I have had no issues and it actually looks richer in color with playback.
I did still got a couple audio dropouts with DVD playback twice during a whole movie last night. Streaming movies or music from the nas seemed fine. I also tested a couple dts audio cd's and they played fine as well.

Do you know anything about this ALSA patch and is it required? http://www.avsforum.com/avs-vb/showthread.php?p=15279769#post15279769
I will be really happy once this is working and I can stop mucking with it. I only get 1 and 2 hour spurts of time to do it and I'll be out of town for a bit starting tomorrow so it's quite frustrating! Trying to do this for someone else as a test build with at least one other wanting one when I'm done so there's a bit of pressure
Appreciate the help! I wish the Live disk would just work with this, I'd be SO happy! Guess I'd learn less too...

I have not seen that patch. It would be nice if they attached a name to it. IE my via patch was VIA patch.c in sound/pci/hda folder, but for 1.0.18a the patch was already included. I do notice in that patch that they spec the alc1200 chipset and the mcp78 (My board) and Mcp7a (p5nXX-vm boards)
All you can do is try it and see. I cannot see where that patch is suppose to be installed. I know that when I ./configure for --all-card --all-options as with my post above it did compile the nvhdmi and mcp78 hdmi req'd files and patches of which both are in the sound/pci/hda directory of Alsa-1.0.18a
What chipset is on your board. I mean North and South Bridge not audio? The two common are the MCP78 and MCP7A seem to be the newest and if so than my solution above should work.

Matt,
if you want to post a small M/C flac file for me to dwnld somewhere I will test it and let you know.

Chipset appears to be MCP7a according to this -> http://www.linux-tested.com/results/asus_p5n7a-vm.html I can tell you that I used a script to compile my ALSA too so I am not sure what compile options got thrown into it. Link to the tutorial is here -> http://ubuntuforums.org/showthread.php?t=962695
I don't suppose there's a chance anyone has plans to update the XBMC Live image to add the latest ALSA and NVIDIA drivers? Pretty please?
