19.10 lubuntu suspend test; on wake no sound

[Chris Guiver]

i was attempting to add this as additional info to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1816394
this has occurred on various model dells (755x2, 780, 960..) but they are all similar) and occurs on occasion on installed systems (18.10, 19.04 & 19.10)

19.10 live QA-Test, I suspended system, waited. On hitting power button to resume the machine resumed as expected, but firefox (when unpaused) was silent with only video showing. Like aforementioned bug, to fix I go to pavucontrol & go to last tab, click the profile off, then back on and instantly firefox sound resumed (it'd been silent.
