i have the same issue too with ubuntu 16.04 mate, but also i have changed my distro to Arch Linux and have the same issue, so i dont think its limited to to Ubuntu.
The other issue is that the bug is intermittent. sometimes it happens other times its not. I cannot work out what triggers this bug. the chip im using is: 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) its a new machine. The work around that Positvek suggested seemed to work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001842 Title: No Audio from HDMI After Switching Monitor Off / On To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1001842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
