If one is using alsa directly then the multi input, multi output benefits of pulseaudio are not available. > > What the kind of weird error is this ? I can't use Firefox and > Audacity at the same time ? What happens if instead of closing firefox, you close the youtube video? How have you got sound configured to use pulseaudio in firefox? In audacity? What if you don't minimize firefox? It could be that minimizing firefox locks the audio device to firefox, preventing pulseaudio from using the output device. > Is this a limitation of the Linux Sound subsystem ALSA ? No, if you are using pulseaudio in both applications, it is happening because of pulseaudio. But, this is the whole purpose of pulseaudio. It allows multiple inputs to be routed to multiple outputs, in various combinations. If there is not an error in your configuration, then this could be a bug in pulseaudio. I have to say this seems unlikely, after all this time that pulseaudio has been in use. But it could also be an error in the interaction of the desktop you are using with pulseaudio. It might be that the desktop is not forwarding pulseaudio requests to minimized applications, so pulseaudio can't reuse the audio device for a new audio request. In that case it might be a bug in the desktop. However, this could be a corner case that is difficult to solve, and thus a known issue where the solution is 'Don't do that!'. > Does this happen for anyone else ? Works fine for me, which is why I think it is something in your configuration. Also, if I use sound as two different users, one switches to another device because it is locked out of the original device by pulseaudio. I have also found that if I play sound as the same user in different applications, they both play at the same time (similar to your use case). Not much point to having sound from two different sources playing to a single output unless I'm trying to emulate a cocktail party or something, but another data point. If you don't want to continue troubleshooting, open a bugzilla against pulseaudio, describing the behavior, and how to recreate it. That will let people more knowledgeable than me look at it. _______________________________________________ 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
