Pulseaudio Output Won't Switch

llewellen · 11-09-2020, 10:51 AM

Manjaro/Budgie 20.0.1 on Dell Inspiron 13 7000
pulseaudio 13.99.3-1
pulseaudio-alsa 1:1.2.2-2
pavucontrol 1:4.0-2

Not selecting headphones output automatically when headphones are plugged in (which it used to do on my previous installation of Manjaro/Budgie).

- default setting: sound to spkrs works fine
- plug in headphones: no sound to spkrs or headphones
- manually change output to "headphones" in Settings>Sound or in pavucontrol
- sound now in headphones and cut off to spkrs
- unplug headphones: sound to spkrs resumes
- replug headphones: no sound to spkrs or headphones

Try udevadm in monitor mode to see if you get an event when connecting. It's not hard to add a udev rule that can run pavucontrol.

I have not used this previously - not familiar with it. Checking through arch-wiki it seems I will need to specify a device to be monitored, else I will get a printout of all udev kernel events, which could be voluminous.

Really? You are connecting and disconnecting devices that often that it would be voluminous?

Sorry, I ran an incorrect script. This is what is returned when I plug in the headphones - nothing.

Code:

[drew@drew-dell ~]$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

I tried on a CentOS system to see if I got any ACPI or udev events, and I don't get either. I think you are dependent on the polling in pulseaudio, and I don't know of a way to trigger a script on that.

Thanks for looking into it. I'll try posting on the Manjaro forum; maybe someone there has a solution. If so, I'll report back here.
