Same here, using a Toneport UX2. I get sound in my DAW, but not on sites (YT, Soundcloud, Bandcamp etc). When I activate my HDMI-sound I get sound from the tv though.
Edit:
Hey, I think I solved this! Go in to sound-settings -> playback. 1. Rightclick on another device (usually you have a device on the motherboard) 2. Pick the option "Make default communication device (Not sure thats what it sais, not English windows here, but pick the one with "Communication") I got sound after that 3. Now you can rightclick the soundcard and make it the default on both sound and communication Hope this helps! Please let us know if not :) Edit2:
It actually has to be 16bit 48000. I tried the 16bit 44000, with my "solution" but it did not work. Allthough when I had 16bit 48000 I had to do the "solution" I suggested to get sound anyway. (Guess it has something to do with multiple audiodevices)
