[pulseaudio-discuss] Occasional heavy click from default speakers, new in openSUSE Leap 15

[Colin Beckingham]

On May 25 openSUSE released a new distro update Leap 15 including 
pulseaudio 11.1
While in general sound works very well, there are occasional loud clicks 
from default speakers
These loud clicks occur when loading a page in a browser or launching 
Audacity for example
A web page will begin to load and all will be quiet until some 
advertising element loads
at which point there may be, or may not be, a short set of loud clicks 
from the speakers
even if the speakers are not set as the default device.
Once these initial clicks are done the rest of any true audio plays 
correctly.

If the sound device has been recently used then there likely will be no 
click,
but after say 20 minutes of no audio activity then calling one of these 
applications
even if it does not play any audio, will very likely produce these 
initial loud clicks.

Not sure how to troubleshoot this to get more info.
This behaviour was not seen in the previous version of openSUSE.
Any suggestions for next step?
