Public bug reported: Hi,
I encountered an audio bug on my new ThinkPad X260. Since I was not able to find a fix online I will try to explain my bug and hopefully get it fixed. I'm using Ubuntu 16.04.1 LTS on my X260 with i5-6200. I want to use HDMI with my Samsung TV to watch videos eg. So I connect the HDMI cable, I get my desktop on my TV and in sound settings I can see HDMI Output. When I select HDMI Output I hear a cracking noise from my TV speakers. When I play a test tone, it looks like the TV needs a 1 or 2 seconds to get the tone so I can only hear the end of the tone. When I repeat this test everything works. But when I open a music player eg. or Chrome with YouTube I hear the cracking noise again and I get no sound on my TV. When I close all applications and start the test tone again, I get the same results. To sum it up. Only test tone works with HDMI, i can select the output but dont get any sound. I attach the alsa-info-alsa-info.sh to this report. As this is my first report, feel free to ask for further outputs eg. Kind regards!
