kiwiclientd sound device unavailable
At 1641 GMT 2023-05-13, all the JTDX instances on one of my Ubuntu 20.04 desktop machines threw a "sound device unavailable" error. I've had this happen a couple of times before, but unfortunately I didn't note when, so this is the first time I've looked into what might be causing it in hopes of preventing it happening again.
From the logs:
13 May 16:41:54 pulseaudio: GetManagedObjects() failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

13 May 16:41:28 systemd: Started GNOME Sound sample caching handling.
That's the only mention of GNOME sound sample caching mentioned in logs going back to 2023-03-15 (and no mention of it at all in logs of another Ubuntu 20.04 desktop here). All both machine do is chew on KiwiSDR RXs feeding JTDX. 1641 GMT is 0041 local, so I wasn't doing anything with it at the time... anyone have any ideas? Looking around about "GNOME sound sample caching" & gsd-media-keys is only making me want to drink a beer.
