How to change audio output on the fly?

I'm using ALSA. I have simple PC sprekers set to my PC's audio jack. Today I bought new headphone that are connected with USB, they worked just fine out of the box. But I don't want to always get up and remove the headphones in order to use the speakers. So when I plug the headphones in, they 'capture' the sound output and I can't get it back to speakers unless I unplug them. Does ALSA have some command that I could switch the audio output? I was searching and found amixer -c and I tried to switch the card but it didn't help. If I open alsamixer I can see the headphones listed as a card.

Re: How to change audio output on the fly?

Install and use pulseaudio. This requirement is one of the main reasons pulseaudio exists.

Though the rest of your description does sound like you are already using pulse, since no automatic switching should happen from USB to built-in and vice versa on a plain ALSA setup. Can you post

aplay -lL
amixer -c0
pacmd list-cards
pacmd list-sinks
pacmd list-sink-inputs

You were right, I actually have pulseaudio. I swear I have not installed it haha.

Re: How to change audio output on the fly?

Please all of them into a single post in the future. That last one is most interesting during actual playback.

What you can do here depends on what you want, for ease of use I suggest you install at least pavucontrol that provides you with quie an intuitive way to do what you want. To prevent autoswitching from happening you will want to comment/remove

load-module module-switch-on-connect
....
load-module switch-on-port-available

in your /etc/pulse/default.pa however at least the first of these two should not be enabled by default and it will be responsible for the kind of switching you are seeing. Is this actually an Arch install?

Another thing that could implicitly enable this would be a relevant audio mixer of your environment, nearly all of the GUI mixers of the big DEs will have a checkbox to set and unset loading of the previously mentioned module.

I tried, but when I pressed preview or submit, the editor just got cleared. When I tried to split it to smaller pieces then the preview and submit worked so I thought that there is a length limit.

Thank you for the help. I'll try pavucontrol.
Yes, this is vanilla Arch install and I haven't messed with any audio settings before. I honestly don't even remember that I have installed pulseaudio, I'll check in the evening how it got to my system. Of course it's possible that I did install it but just can't remember. I don't use DE so I would prefer to have some command so I can do a keybinding to switch the output easily from headphones to speakers.

Re: How to change audio output on the fly?

For a terminal method

pacmd move-sink-input $sink-index alsa_output.usb-Logitech_PRO_X_000000000000-00.analog-stereo #Move to headset, to move to internal card replace that last part with alsa_output.pci-0000_0c_00.4.analog-stereo

You can find the sink index for your actual streams with the aforementioned sink-input command or in a bit more terse format with

pactl list sink-inputs short

You might also want to look at the following script: https://www.freedesktop.org/wiki/Softwa … #index40h3 to move all your streams in one go.

There are also a few command line pulse mixers that might have some more extensive features.
