I have a problem with my sound output on Manjaro KDE. When I first installed it, the speaker sound was fine but the headphones were silent. I checked alsamixer and only saw a master speaker option. I changed the sound card and found a headphone option that was muted. I turned it on and then both the speaker and the headphones played sound simultaneously. I tried to enable auto mute but it didn’t work. After updating the packages and rebooting the PC, I lost all sound output and only got a dummy output. Does anyone know how to fix this?
Update: This morning, I turned on my laptop and booted into Manjaro and everything seemed fine, except for the earphones. They were silent. I repeated the process and they came to life. I turned the speakers down to zero so I could listen through the earphones only. However, when I restarted the laptop, the dummy output problem returned.
