[Solved] Alsa audio output switching issue when unpluging headphones

Hi,
I just reinstalled my Arch, I have a problem with ALSA I guess :
- By default, I have sound with my PC' speakers
- When I plug my headphones, the sound is correctly redirected
- When I unplug my headphones, the sound doesn't switch back to speakers

With pavucontrol I can see that the headphone is correctly detected as "unplugged" and if I change manually the output source to speaker, I have sound again with speaker.
Has someone an idea how to ask alsa to switch back sound to speaker after unplugging headphones ?

Sound card : Realtek ALC299
Environment : KDE Plasma

Thanks

Re: [Solved] Alsa audio output switching issue when unpluging headphones

From a pulseaudio POV that usually happens via the switch-on-port-available module that should be loaded in a default configuration.

FWIW maybe post a

amixer -c0 #... or the correct card index from aplay -l if not 0
pacmd list-cards
pacmd list-sinks

Re: [Solved] Alsa audio output switching issue when unpluging headphones

I tested something else also :
I connected a bluetooth headset and it switchs correctly between the BT headset and the speaker.

Re: [Solved] Alsa audio output switching issue when unpluging headphones

not a useful test, a bluetooth card is a completely separate device that none of the jack logistics that are at play here will have a relevance on.

Were these outputs after headphone plug out (... and non existant speaker playback) ? All seems to look correctly from a general stand point.

Re: [Solved] Alsa audio output switching issue when unpluging headphones

Ye this is weird,  module switch-on-port-available is loaded ?

pactl list modules | grep switch

or did you unload that because of the HDMI device switch that otherwise might happen on wakeup?

Alternatively listen to acpi events yourself and do the relevant switch over see this post for some pointers on how that could look like

Re: [Solved] Alsa audio output switching issue when unpluging headphones

Yes, the module is loaded

$ pactl list modules | grep switch
Nom : module-switch-on-port-available

I will check your link, thanks

Hi,
I just reinstalled my Arch, I have a problem with ALSA I guess :
- By default, I have sound with my PC' speakers
- When I plug my headphones, the sound is correctly redirected
- When I unplug my headphones, the sound doesn't switch back to speakers

With pavucontrol I can see that the headphone is correctly detected as "unplugged" and if I change manually the output source to speaker, I have sound again with speaker.
Has someone an idea how to ask alsa to switch back sound to speaker after unplugging headphones ?

Sound card : Realtek ALC299
Environment : KDE Plasma

Thanks

Its an issue with pulseaudio, I have managed to find a workaround though a bug report is necessary later to help resolve this issue.

I reverted to the 14.0-1 version for these packages from the archive and it correctly switches when unplugging headphones:

libpulse
pulseaudio
pulseaudio-bluetooth

Re: [Solved] Alsa audio output switching issue when unpluging headphones

Should be fixed with the just released 14.2 if I'm reading the release notes right, don't have a setup were I could readily test this myself right now.

I have just checked it out: the old correct behaviour is restored in pulseaudio 14.2
Hurray!
