nvidia hdmi audio

Postby UNIXgod » 16 Mar 2012, 00:01

Going to be setting up a HTPC. Curious if the nvidia GT520 has support for using the HDMI output to carry the audio as well at the video.

Anyone done this?

Not sure if this partical model is supported but there are various NVidia cards on which you can use the audio on the card.

If I'm not mistaken most are detected by [man=4]snd_hda[/man].

I don't know about the GT520 in particular, but I've had audio working on a GT240. The peculiar thing ( with reference to the output below) is that I had to use unit 1 for output ([FILE]sysctl hw.snd.default_unit=1[/FILE]). Zero-two-three did not work.

Code: Select all
gong:~% cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA NVidia GT240 HDMI PCM #0 DisplayPort> (play)
pcm1: <HDA NVidia GT240 HDMI PCM #0 DisplayPort> (play)
pcm2: <HDA NVidia GT240 HDMI PCM #0 DisplayPort> (play)
pcm3: <HDA NVidia GT240 HDMI PCM #0 DisplayPort> (play)
pcm4: <HDA Realtek ALC892 PCM #0 Analog> (play/rec) default
pcm5: <HDA Realtek ALC892 PCM #1 Analog> (play/rec)
pcm6: <HDA Realtek ALC892 PCM #2 Digital> (play)
pcm7: <HDA Realtek ALC892 PCM #3 Digital> (play)

I'm going to go ahead and purchase to see if it works. Thanks for the heads up.

HDMI audio output works fine since recent mav@ work, committed in 9-STABLE in r232798. Before you had to manually disable [FILE]msi[/FILE] (see [FILE]snd_hda[/FILE] man page).
