Comment 18 for bug 1816394

Lubuntu 19.10 QA-test (live 20190519)
dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)

i suspended system & waited, on resume i had screensaver operating which disappeared on movement of mouse. firefox streaming resumed, but without sound. i heard a click though, so press ^R to refresh firefox's window and video restarted with sound!

suspend system again, wait on resuming (power key) i got a different screensaver hiding display (and silence), and movement of mouse I could see firefox continuing to stream alas without sound. pausing and stopping it did nothing. I opened a new tab with different youtube video I'd watched earlier (selected from history) and it had no sound. Tried refresh of first tab and it restarted video but without sound.

pavucontrol & to Configuration tab, click blue square "Analog Stereo Duplex" so it's off, then back on. Instantly a loud din as I'd two music tabs playing at full volume....
