[rodercot]

So here are few more things I have found,

I have worked quite a bit to tailor my xorg file to my setup and switching to 24hz is perfect with the on-board setup with the 220 and the patch and video drivers glx 190 and 195 and as well as the new beta 195.36.03 anything that I have ripped blu or hd-dvd that is 24 gets the stutter unless I switch off diplay rate matching in xbmc.

BUT anything I play from the DVD player that is live like an actual blu-ray disc or animated series is perfectly fine other than an annoyong black screen pause about 10 seconds after I test the movie and stop it this is switching back to 60hz at this point.

I am compiling the new patch right now to test my 240 again and I will let you know asap paoleary - by the way that patch line will not work from the wiki on the scripts dwnlded files as alsa-driver/sound is actually alsa-driver-1.0.22.1/sound

EDIT - 240 works with the latest patch and msi=0 option in the sound.conf file to let you know. I am downgrading to the glx-185 drivers again as hd rips @ 24Hz will not play from my server and anything animated .avi like south park I get sound fine but video is a bunch of green squares, but family guy plays fine from the dvd player at 24hz off the disc. I will test this more. Remember there is suppose to be a bug with lpcm and 190+ drivers that is suppose to be fixed in the 195.36.03 beta driver but I see the issues with all those drivers other than 185 including channel mapping. Kewl - It's like 5 bugs in one and fixing one breaks another.

Reverting back seems to allow everything to play with the match display rate checked in xbmc but I do not think it is switching as normally I would see an icon on the tv screen telling me it is at 1080p 24Hz and then switch back to 1080p 60Hz when done. So there has to be some new options for these cards that are required in the xorg file to allow for switching on the fly with xrandr that I am not aware of yet. I fixed the defaulting to 24hz on bootup by changing the modeline order in my xorg file. but again with drivers newer than 185 I cannot get solid video playback at anything 24Hz. Anyone else see this.

Oh by the way myth tv audio setup just needs plughw:1,3 in both devices under setup-general to work with these cards, you can edit the one that is already there just change the 0 to a 1 in the existing line.

Great Job on this stuff guys, I cannot wait to get this 100%. It is so smooth with the new cards. OH BY the way stay away from the Asus 220 card without a passive heatsink, it sounds like an airplane inside my chassis when running The fan is stupid loud you can hear it over the file you are playing all the time.

Dave

D'oh, yeah, you're right. I've fixed it, but feel free to edit the wiki yourself, it's a wiki after all. :p

Thanks for the 240 info (basically, it wasn't being initialized correctly) and the otherwise extensive feedback. Unfortunately reverting to 185 isn't an option for the G210, since 190 is the first to support it IIRC.

However, are you saying that under 185 with the patch, you have no audio problems? No audio dropouts and all channels mapped correctly? If so then that is very interesting.

EDIT: More diagnostics for later:

Code:

the msi=0 option seems to fix the speaker-test issue as well as the audio and the resulting frame drop issue. But the channel mapping is mixed up. Some are wrongly mapped some don't even sound up in speaker-test. This is also weird as it also seems to effect ac3 and dts passthrough? How can that be?

[rodercot]

@paoleary,

I will double check that this is actually the case with 185 I still have to change the mapping for True HD WITH any of the drivers 185 included via my post a while back by editing the

/usr/share/xbmc/system/asound.conf file and under the win5.1 section match all the tables from what they are now.

like 1.1, 2.2, 3,3 4,4 5,5 this realigns center channel to center channel properly. I have no problems with DTS in any drivers I do not have any 7.1 aac files. but I will get alan's files and test them all later tonight and let you know for sure.

Seems there is still major powermizer bug affecting the 240 which causes the memory to run at a 1/3rd of what it is suppose to there is a big thread at nv about it. google GT240 xorg files and it is the first result. This is a with all the drivers including the newest 195.36.03 people are not happy.

The thing that is confusing me is that with ANY of the 190+ drivers I cannot play 24hz files from the server BUT anything I play live from the dvd player works just fine it switches from 60hz to 24hz no audio problems at all 2ch, 5.1ch dts or dd and true-hd, lpcm and dts core stripped from dts(hd or ma) all that works and this is with Blu-Ray, Animated or Regular DVD movies, I cannot see it being a bottle-neck between the lan and the pci-e bus can you, I though we were over that 32bit hurdle ages ago but it would seem that this may be the issue for at least stuttering playback from my lan but DVD playback is perfect. I am grasping at straws with this ofcourse.

I am sure there must be some new options in the xorg file that need to added or old ones that need to be removed. I have looked the driver readme but nothing seems to have changed across the 190 drivers evolution.

keep testing I guess. I think i will install my VNF100 Zalman on the 220 and test with it, Until they get the bug fixed on the 240 cards it is running slower than the 220 anyhow.

Dave

Thanks for that, I have never been affected with this bug, I run svn 27017 and have been for a while and before I started playing around with these cards I had no issues and I can back out of all these patches and upgrades and default to my 9300GT on my P5N7A-VM and all would be fine.

I also have a zotac IONITX-F-E setup with a blu-ray player that is fully configured as well with 27017 and it works perfectly with my xorg file and all my hd, bd, .avi etc work just fine at 24hz switching with that machine.

No! this problem is directly related to how the new video cards and how they interact with each other. All three 190 drivers perform exactly the same way on either the GT220 or GT240, which REALLY BITES, as the smoothness and blacks when they do work ARE JUST AMAZING.

So I plan on building up another test bed and play with both cards and xorg.conf options until I find the culprit to this issue and xranadr I feel it directly related to dynamictwinview but have not played enough yet to confirm it.

Dave

GT240 - Audio working over HDMI !!!! Ubuntu 9.10 here.

Thank you to paoleary and all of you. Posts were very helpful.

Thank you to paoleary and all of you. Posts were very helpful.

Please--if you come back, qualify "working" as well as you can. Do you have all 8 channels mapped properly (to the extent you can test)? Problems with occasional loss of audio/stuttering? That feedback will help keep me from breaking things as I try to fix those problems that I know at least affect the 210 and 220.

Welcome back, XBMC!

The most current instructions are here.

Other useful ongoing links:

• The alsa-devel thread discussing the patchset; currently in the ALSA snapshots packaged by Takashi Iwai.
  
• The git repository that the snapshots are pulled from. This is Takashi Iwai's personal tree and represents the state-of-the-art for ALSA HDA.
  
• The official ALSA driver repository. These get pulled into official releases.
  

The latest news is that the enable_msi=0 option may no longer be required with new snapshots. I do not have the time to test this right now, but if someone can verify that (1) the current snapshot has this patch, and (2) the explicit option in sound.conf now does nothing, we can simplify the installation even further.

Sound working with Gainward G210 on ubuntu 9.10!
Had to use "# 3.2 The Original Patch" to get the device listed in aplay -l.
Thanks to everyone who put the guide together.

[paoleary]

Patch for GT220 has been dropped in! Once this hits the snapshot (not sure yet, haven't downloaded it) the process should be down to configuring the module options.

I can now legitimately say I've contributed to the Linux kernel!

Hi there,

I'm the unfortunate owner of a GT220 in my HTPC and I can't manage to get any hdmi audio output working. I've already been able to let a nVidia ION chip work fine with XBMC/HDMI audio output on another system, but with the GT220, I'm stuck ...

I'm running Ubuntu Karmic with :

Code:

ii  nvidia-settings                         180.25-0ubuntu1                         Tool of configuring the NVIDIA graphics driv

I grabbed the latest http://ftp.kernel.org/pub/linux/kernel/p...ot.tar.bz2 which includes the GT220 patch and installed the modules :

Code:

./configure --with-debug=full --enable-dynamic-minors --with-moddir=updates
make
sudo make install-modules
sudo reboot

After that, I were able to see 4 NVidia HDMI output with 'aplay -l'. I applied recommended changes :

Code:

$ cat /etc/asound.conf
pcm.!default hdmi:NVidia
pcm:iec958 hdmi:NVidia
$ cat /etc/modprobe.d/sound.conf

options snd-hda-intel probe_mask=0xffff,0xfff2
$ sudo reboot

At this point, I'm left with only one HDMI NVidia output :

Code:

$ sudo alsamixer -c NVidia
[did unmute the IEC958 output]

LOL, hey, it happens. Thanks for the confirmation on the current state of the snapshot. I'll edit the wiki to remove the GT220 patch instructions.

[snoopy20]

I'm having the same problem - no sound - but my user is in audio group (no sound with root either). I'm running at 240 with alsa 22.1. I entered the correct txt into sound.conf which caused the four hdmi to switch to 1 spdif that I unmuted.

When I play anything using speaker-test or aplay using plughw:2,3 which is the correct device I get no sound.
