This is my first post, so I apologise for any formatting mistakes or missing information. Please let me know and I’ll correct it accordingly.
I’m experiencing an issue with PulseAudio where the built-in laptop speaker and headphones are simultaneously producing output when the audio jack for the headphones is plugged in. I found a work-around where I have to manually open PulseAudio every time I restart Manjaro and first select Speaker from the drop-down (under the Output Devices section) and then Headphones. After this it only produces output through the headphones as expected.
Initially my sound wasn’t working at all and I had to follow these steps to install the appropriate firmware:
sudo pacman -S sof-firmware alsa-ucm-conf
I also installed a package pavucontrol as part of this process.
I’m using a Dell Vostro 5590 with an up to date Manjaro KDE installation.
Kernel version: 5.8
The device giving me issues is sof_hda_dsp Speaker + Headphones
I used an Ubuntu installation before now on the same laptop and didn’t experience any similar issues.
Thanks in advance!
