I am running GNU Radio Companion with KDE, and am not able to hear any sound when using an Audio Sink. I have tried producing sound by making one of the FM receiver examples available online, as well as by connecting a signal source to directly to an audio sink. When I run either of these examples, I can see that a signal is going into my audio sink, but no sound is heard.
I have tried setting the device in the audio sink to "pulse", "hw:0,0", and "plughw:0,0", as suggested in other places, without success. GNURadio does not show up on the list of applications producing audio in "System Settings > Audio > Applications".
I was previously able to hear some (very choppy) sound from the FM Receiver example. I am not sure what changed. As a note, I did recently install KDE alongside GNOME, and then uninstall GNOME. I don't think this caused the problem, but figured I would mention it just in case. Any suggestion as to what might be wrong would be greatly appreciated. Thank you!

I tried everything else I could think to do, including reinstalling packages related to PulseAudio, ALSA, and GNURadio, and looking at a bunch of their config files to see if I could find anything amiss. None of this helped. Eventually, I reinstalled the gnome group and rebooted. This fixed the problem, even when using KDE. I will have to do some digging to see what gnome did that fixed things. The sound is still very choppy, but this seems to be a more common problem, likely with an unrelated solution.
