HDMI on GTX240 still not working

acharnley · 04-12-10, 05:05 PM

Problem: no sound over HDMI
Setup: latest NVIDIA, latest ALSA snapshot, correct probe_mask so that HDMI SPDIF shows 1 instead of 4 devices. Unmuted.
Test: send sound (speaker-test etc) to hw:2,3 (which is correct) and it plays but nothing comes out. Works fine in Windows

And finally

, I'm running Slackware64-current, alsa-snapshot (yesterdays), NVIDIA 195.36.15

Ignore the first HDMI my onboard doesn't really have one.

Disabling onboard sound doesn't make it work on the 240.

I am completely stuck.

acharnley · 04-13-10, 04:23 AM

I've sorted it, it's a bug with the NVIDIA drivers. If the resolution of the HDMI port is switched to "off" in NVIDIA control panel then SPDIF isn't passed through either.

In windows this can be done, in my case I have a Sony Reciever attached which doesn't need video. Having to use "clone" instead of "off" means you cant use Twinview on the other two video outputs.

Enabled onboard video to handle one screen and twinview turned off for now.

I can confirm this on my Palit GT 240 GDDR5. HDMI audio does not work when the HDMI output is not sending video. This makes things very difficult since I use a CRT connected to the VGA port as my primary monitor and want to have audio from my receiver where my secondary monitor (a TV) is connected as well. If a game runs in fullscreen and changes the video mode so that the HDMI video output turns off, I get no more sound. I'm using the driver 195.36.15 packaged in Ubuntu repositories.

Please fix this.
