@leocg Just the standard non-gaming Opera browser, so I guess Opera One?

When my computer is connected to my Bluetooth speakers or headphones, no sound from Opera is coming through, even though everything else on my computer is working fine. For example, I can play a song on Spotify and a YouTube video (through Opera) simultaneously, and only the Spotify audio comes through on my speaker.

When I disconnect from the speakers, everything on Opera works fine and plays audio normally. What on Earth is going on here??
