OK, Stephen, could you prepare the patch including all missing IDs?
I wrote an new patch with three new codec IDs for Nvidia Fermi cards. I attended to use existing IDs and online technical specifications to get two others cards :
- Nvidia GeForce GTX 470 : id = 0x10de0015
- Nvidia GeForce GTX 560 Ti : id = 0x10de0016 (works fine)
- Nvidia GeForce GTX 570 : id = 0x10de0017
They don't appear to match our Windows driver. Where did you get the values from? (0x17 isn't in the Windows driver at all. 0x15 shouldn't be a GTX 470)
I ask to a reseller, it seems a bad idea.
The only way to find the values that I know of would be to plug the card in, run Linux, and look at the ALSA /proc files. (Perhaps there's some equivalent tool under Windows)
If I can help, where are these values in the Windows driver ?
They encoded into the binary. I doubt they're user-accessible.
So, I think the best way to proceed is for you to modify your patch to add IDs 0x15 and 0x16 only. I'm pretty sure ID 0x17 isn't assigned to anything. Let's not remove any NVIDIA IDs even though I'm pretty sure a couple aren't actually assigned; if I'm wrong, we'd just have to add them back later, and having them in won't harm anything.
OK, I modified Richard's patch to get rid of 0x17 and merged now to sound git tree.
thanks,
Takashi
