I installed eOS on a HP Envy x360 Convertible 13-y0xx. Bluetooth is doing something strange. If I'm connected to my Bluetooth headsets, open YouTube through Epiphany, everything sounds normal. But if I open YouTube through Firefox it'll play the audio through the laptop speakers.
Here's where it gets crazy. I can play an MP3 song through eOS's music player at the same time I'm playing a video on YouTube through Firefox and I can hear both Bluetooth audio AND the laptop's audio playing at the same time. They're both active.
After fiddling around with the settings and installing Blueman, I got this notification. I don't know if this has anything to do with it.
