Description John Williams 2016-11-09 02:02:40 UTC

Firstly, thanks for a great audio solution for GNU/Linux!

However, I have a problem that goes away when I kill pulseaudio. I have a home network with a few boxes (2 x GNU/Linux, 1 Winblows) connected by ethernet, and others by WiFi. When one of my directly-connected machines has networking active, WiFi stops working for all devices that attempt to connect. If I disable networking on this box (Running Fedora 24), WiFi works fine. By trial an error I found that if I kill pulseaudio (and set autospawn false), my problem goes away. Also, this problem does not occur if my other GNU/Linux box, also running Fedora 24, is connected with networking enabled and pulse running.

I am a user, not a coder. But I know my way around the shell. So, what can I do to help diagnose this problem?

Thanks,

John

Did you enable "Multicast/RTP" in paprefs at some point? If yes, this is probably the same problem as has been reported here: https://bugs.freedesktop.org/show_bug.cgi?id=44777

That was it! Thanks so much! I see from the discussion on the bug report
you showed me that this has been a known issue for some time. Perhaps the
GUI for paprefs could be amended to show a warning about enabling this
option?

Thanks again for your quick and effective help,

John

You're right, we should add a warning to the UI.
