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').

Etienne URBAH, as per https://www.asus.com/Motherboards/M5A97_R20/HelpDesk_Download/ an update to your computer's buggy and outdated BIOS is available (2603). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid.

With kernel version 4.3.0-040300rc4, the issue stays essentially the same. But the sound output now systematically starts at the BEGINNING of the 2nd time I hit any 'Test' button.
