I have a weird problem. When I want to watch a youtube video on my television (HDMI) I switch the sound via soundsettings to go through hdmi. But no sound is played on the television. Whenever I play a video on VLC, or play music via rhythmbox, this problem is not present. In other words, the audio is played fine via hdmi on my TV.
This problem is present on my Lenovo Ideapad u330p AND my Asus Zen UX305F.
My girlfriend's laptop still runs 14.04 and there the problem is not present. Is this a bug?
Edit: the audio in VLC works fine: in VLC one has the option to choose the audio device. Even if in sound settings the speakers are the sound device, I can choose to play video via hdmi in VLC. And this does seem to work.
