I presume that the "most > correct" pipeline source object type to use is pipewiresrc. alsa is the hardware layer. It supports the drivers for all audio devices on the system. Pulse and pipewire give access to alsa devices in a more user friendly way and add capabilities that alsa doesn't have. They both use alsa to access the actual devices. The official switch in Fedora is from pulseaudio to pipewire as an enhancement layer. I think I still see new pulseaudio versions available, so maybe it will still work. But, whichever you choose, it should be the only one active on the system at any time. Two managers (pulseaudio and pipewire), one employee (alsa), not a recipe for good things happening. > If the answer is to use pipewiresrc, how can I inspect the pipewire > "devices" seen by gstreamer? `gst-device-monitor-1.0` only shows the > expected PipeWire devices via the ALSA api.

There doesn't seem to be a clear translation from the alsa device assignment / label to the pipewire device assignment / label. My investigation was months ago, so it could have changed in the meantime, and could still be changing. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
