Sound changes to wrong device & output, shows speakers in line out always as 'unplugged'

Scenario: I’ve HP Probook G1 Intel Haswell -laptop in dock connected with speakers in ‘Line out’ and that’s output mostly. Sometimes I use USB-headset which stays connected and I only change output. This used to work fine until recently. I have HDMI output but it should be never used. TW has recent updates and kernel.

Problem: In Xfce’s Pulse audio plugin it defaults to wrong device: HDMI or USB-headset. if I try to change device to ‘Built-in Audio Analog Stereo’ it doesn’t have an effect (plugin shows shows the same device). In pavucontrol ‘Output devices’ -tab sound device: Built-in Audio Analog Stereo port keeps changing to. Speakers if I set it to ‘Line out’, it shows it as ‘Line Out (unplugged)’. I assume that’s related to problem.

If I then play something in pavucontrol Playback section the device keeps changing to wrong setting too. If I change it to analog stereo, I can hear the sound from speakers just fine.

How could I make ‘Built-in Audio Analog Stereo’ output always be the ‘Line out’ and make that the default when playing something? (as it has been before)

  • would be nice if I could get the HDMI-device off permanently as I never use it. changing it in pavucontrol doesn’t stay.

‘Line out’ the output and make it stay until I need to change it to USB-headset as I’ve done before?

Extra info:

  • I’ve tried different speakers and it has same outcome.
  • USB-headset’s port shows in pavucontrol as Speakers, don’t know it should do that.

See if this helps with setting the default sink…

I did as suggested there and set ‘set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo’ at bottom of the file and restared pulse but doesn’t affect the problem.
If I could just force pulse to accept somehow that the Line out is plugged. I’ve ofc unplugged and plugged it several times but pulse remains determined that it’s unplugged.

  • I’ve also deleted ~/.config/pulse and reinstalled alsa & pulse, but it just the same.

You need to set the active port. Check the current active port using…

pacmd list-sinks

or

pacmd list | grep "active port"

Assuming card 1, try executing something like

pacmd set-sink-port 1 analog-output-lineout

If that works as desired, you can set it permanently by adding the following entry to /etc/pulse/default.pa

set-sink-port 1 analog-output-lineout

I can change the port of card to “Line Out (unplugged)” via pavucontrol or pactl so it’s right. The problem then is the default/fallback device which I haven’t yet been able to change. AFAIK that’s used when I for example open new web page which plays audio. It’s then either HDMI or USB-headset depending if USB-headset is plugged or not. After command ‘pactl set-default-sink 1’ or ‘pactl set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo’ gives no output but ‘pacmd list-sinks’ still shows asterix on either HDMI- or USB-device and new web pages play audio through that.

In pavucontrol’s output -tab I can’t make only analog stereo’s fallback icon being selected. either HDMI/USB is being selected or HDMI/USB and analog stereo.

I can change device on Playpack-tab but I have to do it every time new application starts playing audio.

So you haven’t been able to set line out as default via /etc/pulse/default.pa entry to set the sink port?

Just in case this is relevant here…

This looks as expected…

        active port: <analog-output-lineout>

For some reason, it’s just start to work! (atleast for now :-). So for new applications analog stereo is selected and sound comes from speakers. In pavucontrol analog stereo’s output is set to Speakers which I thought meant just the laptop’s internal speakers since there’s no other port for that, but the sound comes from the speakers connected with line out :-o Before when that output was selected sound did come from laptop’s internal speakers. Don’t know why that changed but now it works as it should.

I have added the default as is seen below but new sound applications sounds sink had been HDMI/USB nevertheless.


### Make some devices default
#set-default-sink output
set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo
#set-default-source input

Ok now I think I figured out where the problem is. If I change the angle where laptop sits on dock, the sound begins to come from speakers connected to lineout and I finallyget pavucontrol to show “Line out (plugged)”. Also if I move it, it goes to “Line out (unplugged)”. I didn’t realize that connection between laptop and dock could be a problem since all other cables connected to dock for without problems.

Good to find something definitive about the connection behaviour though. :slight_smile:
