At first I thought it was a bad audio file, but it turned out that everything I play is choppy. Then I thought that some process is clogging the CPU or IO, but it wasn't that either. After some searching, I opened sound settings and found out that Line Out audio output is rapidly disappearing and reappearing from the list. I checked the alsamixer and same thing was happening in its window. I tried to restart the computer, and the problem disappeared only to come back again after a short time. I still have my old 14.04 installation, I rebooted to that and everything worked as it should. I have never seen anything like this, I have no clue what is happening and I have no idea what to check. dmesg output showed nothing related to sound. Since it is very unusual, I have attached a video of what is going on.
