Nvidia card is not detected as a sound device / no HDMI sound

G

gabe.rust

My Nvidia graphics work flawlessly with x11/nvidia-driver-340 on GNOME, but I went to use an HDMI TV with my laptop (Acer Aspire 5920), and could not find sound settings for HDMI output. I did a little bit of research, and found that other people with the same issue usually have some sort of configuration issue, but in my case, my system does not even see the nvidia card as a sound device. Any ideas on how I can fix this?

Maybe I need to install some sort of Intel audio driver?

Code:

Apparently you don't have anything to detect.

That's Realtek ALC1200.
 
That did the trick, but it seems a bit inconvenient to switch every time i switch audio output. I might write a GNOME shell extension to do it from the task bar or something :)
 
So now I have the issue that some applications use the laptop speakers (firefox) and others use the hdmi (rhythmbox). Is there a way I can force applications to use the default sound unit?

Did you install audio/pulseaudio? If so, use audio/pavucontrol to set the output for firefox (I assume you use packages and as far as I understand it, firefox is compiled with pulseaudio while most other programs defaults to oss).

Also check the output of: cat /dev/sdnstat.

I don't know much about firefox, but I compiled it without pulseaudio support and still have sound. I do see that it has sndio as a dependency though, although I never configured that one.

I wrote it based on my experience using packages, not ports. I assume the OP used packages also, see www/firefox.
Configuration Options ===> The following configuration options are available for firefox-67.0.1,1: CANBERRA=off: Sound theme alerts DBUS=on: D-Bus IPC system support DEBUG=off: Build with debugging support FFMPEG=on: FFmpeg support (WMA, AIFF, AC3, APE...) GCONF=on: GConf configuration backend support LIBPROXY=off: Proxy support via libproxy OPTIMIZED_CFLAGS=on: Use extra compiler optimizations PROFILE=on: Build with profiling support TEST=off: Build and/or run tests ====> Options available for the multi AUDIO: you have to choose at least one of them ALSA=on: ALSA audio architecture support JACK=on: JACK audio server support PULSEAUDIO=on: PulseAudio sound server support SNDIO=off: Sndio audio support ===> Use 'make config' to modify these settings

The OP has sound, only on different outputs.
