pulseaudio, nVidia HDMI/DisplayPort, nothing...

dimm0k · 10-31-2016, 09:16 PM

Currently running Slackware64 14.2 and everything was great until I upgraded my video card to an EVGA nVidia GTX 780. this card still has the DisplayPort output, which I'm using with the same monitor setup that worked fine in terms of audio output because this monitor has speakers built in. With this new video card there is no audio coming out from the DisplayPort so I'm hoping I'm just missing something. I know the monitor and speakers are fine since they worked with the old video card and just to make sure I plugged in a Chromecast and that worked as well. When audio is playing I do see in pulseaudio that the meters are moving, but there's just no sound. any suggestions or is this video card bad?

If you run:

Code:

pacmd list-sinks

what is listed for device.profile.name? I ask because on my computer, when I hook up HDMI via the DisplayPort output, I always run something like this to set the audio output to HDMI:

Code:

pacmd set-card-profile 0 output:hdmi-stereo

(You can also just run 'pacmd' to get into an interactive mode. Once there, 'help' will list many other commands and queries you can do.)

so here's the funny thing, I actually see two under device.profile.name shown below. does this mean they're conflicting?

Code:

{~}$ pacmd list-sinks | grep profile
		device.profile.name = "analog-stereo"
		device.profile.description = "Analog Stereo"
		device.profile.name = "hdmi-stereo"
		device.profile.description = "Digital Stereo (HDMI)"

I think it means you have more than one sink available, but I'm not sure if that's a problem or not. When I connect to HDMI and run the command from my previous post, I just see the last two lines from your output. So that might be the problem, or there might be a legitimate reason why you would have two sinks, but I'm not sure.

so I believe the reason for the two profiles is because I'm combining both the analog and digital connections so that audio can be played through both simultaneously. I was able to get this setup working in Windows so that verifies all of the hardware is working... while in Linux it just won't allow me to play audio through this connection. attached you'll see what I see in Windows and that works, while the other screenshot is what I see in pulseaudio. I'm connected from the video card to the monitor via DisplayPort.

The first thing I would do is temporarily kill pulseaudio, then use "aplay -l" and/or "aplay -L" to locate all my audio devices. Then use "speaker-test" to see where the audio is. The new csrd may have a different "default" and pulseaudio is still expecting the old one. It might be a good idea to check "lsmod" to make sure you aren't missing a module.

(you can ignore the .aroundrc part).

big n00b question, how do I temporarily kill pulseaudio? whenever I kill it with 'pulseaudio -k', it pops up again
