How to use 340.xxx nvidia driver for openelec 6?

[docolli]

I have used successfully version 5.0.8 on my HTPC that is connected via onboard graphics and HDMI to my TV. I've got a Full HD picture and sound, after selecting HDMI#1 in Kodi audio settings.
After 6.0.0 was released I upgraded, but since then I have had no sound via HDMI. I need to use the nvidia-legacy version build since my nVidia chip is no longer supported by the driver version 352.63 used for 6.0.0 generic. It costs me several hours for finding the cause, but today I found the following page, which showed me that with version 6 of openelec I've been "falling through the net" with my nVidia hardware: http://www.nvidia.com/object/IO_32667.html
I have Geforce 9300 with nForce 730i (0x086C) and this hardware is no longer supported by latest 352.xxx driver and is not supported by 304.xxx driver, only 340.xxx driver build is supporting my (and probably other users) hardware.

List of nVidia Linux driver versions: http://www.nvidia.com/object/unix.html

I know, that nVidia states that Geforce 9300 is supported by the 304.128 driver (http://www.nvidia.com/Download/driverRes...0399/en-us) , but the link above shows other information, which (from my experience) is the truth for the 304.xxx driver.

So my question: Is it possible to add another version of openelec 6, that has build-in 340.xxx nvidia legacy driver? Since I found quite a lot of hits in the web of people using openelec and having problems with HMDI sound, maybe usage of the 340.xxx driver will also solve their problems...

Or (since I can make a VM with necessary Linux build system), how can I replace the 304.xxx driver in the source code with the 340.xxx build and build my own openelec version?

Maybe this version of OE will be OK
see here http://openelec.tv/forum/115-vdpau-nvidi...r-ion-ion2

There is such a thing as the OpenELEC Legacy build, for ION machine and the like.
Have a closer look at the downloads page on the OpenELEC website.

legacy nvidia drivers .....ION
is not the same as 340.xxx

I'm aware of the small gap between 304.xx and current but it only affects a tiny number of cards and so far there's only been posts or complaints from 2-3 users so it's not a widespread issue, i.e. not enough to justify another official build between Legacy and Generic (not sure what we'd call that!?). At some point we will need to bump the Legacy driver version and it will probably be bumped to 340.xx, but not just yet. There are several "community" builds in circulation with 340.xx (as linked above) that can be used or it's not hard (it takes time, but isn't hard) to self-build.

Thanks for all of your help and the link to a build with 340.xx driver. I've already downloaded it.

But yesterday something magic has happend on my HTPC, since suddenly I had sound through HDMI #1 with 6.0.0 nvidia-legacy (304.128 driver) installed in my internal SSD. So I decided not to upgrade now and find out what has happend.

Today evening sound was still there, so it survived a (soft) poweroff without problems. My idea was, that I had started 5.0.8 from a stick as a live system yesterday, which has 340.xx driver. And maybe this 340.xx driver is able to init something in my hardware that sound through HDMI works. So, to break HDMI sound again, I put my HTPC completely from line power and unplugged HDMI cable. I succeeded, HDMI sound at 6.0.0 (304.128) was not working again. I then started a live 5.0.8 from the USB stick and after selecting HDMI #1 I had sound through HDMI. However, rebooting the HTPC from SSD to 6.0.0 did not bring back sound as happed yesterday.

So currently, I don't know why I had sound in version 6.0.0 with 304.xx driver. Something magic has changed in my hardware that is only persistent until the mainboard is completely from power.

So finally I have upgraded to the 340.xx build of 6.0.0 and I have sound through HDMI.

I also have setup a Debian System to be able to make my own build with 340.xx driver. Since I am not an openelec developer is there any help of how to change driver to 340.xx? My idea is to grab the latest sourcecode (or the latest stable), patch it to change 304.xx to 340.xx driver and build.

Build the Nvidia_legacy project as it will build quicker (no need for AMD/Intel drivers etc.) and edit the driver version in the nvidia-legacy package.mk to the driver version you want.. that's all that's needed.

Thanks, using openelec 6.0.0 with driver 340.xx from the link helped.

Also I was able to get the latest build (OpenELEC-Nvidia_Legacy.x86_64-7.0-devel-20151208091023-r21674-gc5875ae) and change driver to 340.96. Principally this self-made build also worked, however, VDR client did not work after upgrading. So now I am using the 6.0.0 with 340.xx from above link.

Is there anything known, that VDR is broken in latest build? But this is related to another topic, so we should discuss there ;-)

addons need to be rebuilt for 7.0 .. it's on the staff to-do list
