How to use HDMI sound output for VLC and headphones for everything else


Hello,
In Windows, I make the laptop's speakers the default sound output then in VLC I choose HDMI as the Audio device. Then I can use my headphones to listen to whatever I want and let the rest of the house watch a movie on the TV.

How can I achieve the same result on Linux Mint 17.3 running KDE and VLC 2.2.1

It depends on your sound setup. For basic alsa:

FILE: ~/.asoundrc
Code:
defaults.ctl.card 0
defaults.pcm.card 0
defaults.pcm.device 3
Where defaults.pcm.device is 0 for the speakers and 3 for the hdmi audio out. As hinted to by:

$ egrep -r -i hdmi /proc/asound/*
/proc/asound/card0/pcm3p/info:id: HDMI 0

For pulseaudio

$ pavucontrol

And select the needed thing, probably by disabling everything but it.

I subscribed to this thread as I was interested. Is Phonon a plugin to PulseAudio? I've always found PulseAudio a little too clever for its own good on switching inputs (much like Windows offerings) but is Phonon a little less annoying?

I'm not running Linux Mint, but I am using KDE, and if I right click on the volume icon in the panel and select Audio Volume Setings > Audio Volume and Under the Applications tab I can select any output on my system for the given application

I would think you'd change the audio device in VLC the same way as on windows. Your HDMI device would be named something like hdmi:CARD=HDMI,DEV=2

What do you use for letting the rest of the house watch a movie on the TV?

EDIT: You can directly use PulseAudio volume control (pavucontrol) to switch audio devices for a program as it is running.

I'm so sorry for the late reply, the internet is down and currently I'm replying from my phone

@273 I'm sorry but i don't understand what you mean

@TheEzekielProject only options in pavucontrol are to mute, lock channels and volume control

@DJ Shaji there is only one device listed which is the working sound output so it's either "built in audio digital stereo (HDMI)" or "built in audio analog stereo"

I'm not sure what you mean by i have a 3 meter HDMI cable connected to the TV so anything from a YouTube video to a game can be run on the TV as a separate screen


Please note that i manually change the sound output to and from HDMI using a KDE widget that changes the settings for me
