This issue seems to be NOT specific to AMD/ATI Tahiti XT : For example, it has been reported with NVIDIA GTX 970 at https://askubuntu.com/questions/874320/audio-starts-playing-3-5-seconds- after-video-does
So, I suggest to report this issue at https://www.alsa-project.org (instead of 'radeon at freedesktop'). Besides, I suggest to change the title of this issue to the following more precise title : Sound output using DisplayPort is NOT played during the first 3-5 seconds (on several audio hardware) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1504227 Title: Sound output starts several seconds late using DisplayPort with [AMD/ATI] Tahiti XT HDMI Audio [Radeon HD 7970 Series] [1002:aaa0] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1504227/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
