ALSA audio silent on some hardware - test - Fedora mailing-lists

12 Aug 2022


      I have F36 installed on my laptop and desktop computer.
On my desktop computer apps using other audio frameworks than ALSA work fine, while apps using ALSA are silent.
On my laptop everything works fine.
"alsactl -info" lists all the hardware on my desktop.
When using an app that uses ALSA audio on my desktop the audio source does not show up in pavucontrol, while it does show up on my laptop where it also works fine.
Below is a list of the hardware in my desktop provided by ALSACTL:
