Couldn't play any video in browsers ?

Hi,

Couldn't play any video in browsers (chromium, firefox, vivendi etc.) when SMPLayer is in background (even not running...)
Videos seem to be loaded but never start (youtube, vimeo, dailymotion etc.)
Error message in youtube is: "if playback doesn't begin shortly, try restarting your device"
Videos start well in browsers if I quit SMPlayer

What could I do to check further ?

Thanks for your help

config:
Ubuntu 19.04
SMPlayer 19.5.0 (9214)
MPV 0.29.0

That's strange. Try changing the video and/or audio output in preferences -> general and see if that helps.

Looks like it was coming from the alsa audio output driver...
I have selected "default" instead "alsa" in audio output driver menu and now it's working
Thanks
