Before You Begin/Notes
This guide assumes that you have a GeForce G210, GT220, or GT240 card, are using a reasonably up-to-date system, and that you have at least the nVidia 190 series proprietary drivers installed.
Note that this is a work in progress and there are still significant limitations to the current method. The GT240, while it becomes recognized, does not yet work. Channel mapping is known to be incorrect.
Getting ALSA
You will need to compile a patched version of ALSA 1.0.22.1 from source. An easy way to do this is with the ALSA Upgrade Script. Alternatively, you can download the sources from the ALSA Project. If using the upgrade script, only complete the first (-d) step. If using downloaded sources, this how-to assumes that you've unpacked them to /usr/src/Alsa-1.0.22.1/.
Patching ALSA
First, download the patch. This how-to assumes that the patch is in your home directory and is named alsa_nvidia.patch. This patch modifies patch_nvhdmi.c so it recognizes the G210, GT220, and GT240. Apply the patch by entering:
$ sudo patch -p1 -d /usr/src/Alsa-1.0.22.1/alsa-driver/sound < ~/alsa_nvidia.patch patching file pci/hda/patch_nvhdmi.c $
Compiling and Installing ALSA
If using the upgrade script, run the -c and -i steps now (hint for the adventurous: make the -c step faster on multicore systems). Otherwise, follow the standard ALSA configure, make, and install process, but do not reboot.
Setting Module Options
$ sudo cat - >> /etc/modprobe.d/sound.conf <<EOF > options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2 > EOF $
Where there is a single "0xffff," for each card that appears before the nVidia device in `aplay -l'. In the example, the nVidia device is Card 1.
Finishing Installation
Now, reboot your system. Using `alsamixer', select your nVidia card (select it from the F6 menu, or use the -c option) and unmute the S/PDIF output (press "m"; the box should change from "MM" to "OO".) Enjoy!
