[Bug 1504227] Re: Sound output starts several seconds late using DisplayPort with [AMD/ATI] Tahiti XT HDMI Audio [Radeon HD 7970 Series] [1002:aaa0]
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to your computer's buggy and outdated BIOS is available (2603).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.
Thank you for your understanding.
** Description changed:
I am using simultaneously :
- an audio headset connected to the analog audio output,
- a DisplayPort cable to connect my display to my 'AMD Tahiti XT [Radeon HD 7970 ...]' graphics + sound card.
Using the 'Sound' panel of 'gnome-control-center', I systematically get
following behaviour for sound output :
- If I choose the 'Line Out - Built-in Audio' device, the sound output comes immediately :
- For example, inside the 'Test Speakers' window, the correct sound systematically starts as soon as I hit any 'Test' button (under 'Front Left' or 'Front Right').
+ For example, inside the 'Test Speakers' window, the correct sound systematically starts as soon as I hit any 'Test' button (under 'Front Left' or 'Front Right').
- But if I choose the 'HDMI / DisplayPort - Tahiti XT HDMI Audio [Radeon HD 7970 Series]' device, the sound output starts several seconds LATE :
- For example, inside the 'Test Speakers' window, the sound starts at the end of the 2nd time I hit any 'Test' button (under 'Front Left' or 'Front Right'). Then continuous sound is correct and in sync.
- But after approx. 10s of silence (no sound to output), new sound output starts several seconds LATE again.
