[opensuse-factory] Sound delayed when playing via HDMI
When I play a video i.e. in Firefox or VLC or when I use Musescore, the sound is not in sync with the picture. It is delayed about 1 second. When I go back to VGA and the analog sound device, sound is in sync. I searched for it on Google, but did not find a solution. Any hints? -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

This is normal. When using digital video connections like DVI or HDMI, you always end up with video and audio getting out of sync due to the difference in time it takes to process the audio and video data. However, normally the software will take care of the problem but it requires both video and audio to be passed digitally to the display device, e.g. HDMI video including audio. If you just pass the video signal digitally but the audio signal stays analogue, then there is no way for the software to make sure the signals are in sync.
When I go back to VGA and the analog sound device, sound is in sync.
How is your audio signal connected to your speakers? Do you just use an analogue cable to your stereo, do you use headphones or do you use HDMI audio? Without knowing the details of your setup, it's not possible to determine the cause of the problem. If your connection is all digital, then you might have run into a bug.
I searched for it on Google, but did not find a solution.
For VLC, you can always use the keys "j" and "k" to adjust the audio delay until both video and audio are in sync again. Adrian -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

The sound using HDMI comes via the HDMI connection; it is the only connection between my system and the display with the speakers.

That might be a solution for VLC, but I get my video via Firefox, which displays it in a Firefox window. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Then you should check the settings of your TV which should have a menu to adjust the sound delay for an HDMI connection. I think it's also possible to adjust the delay using Pulse-Audio, but I'm not sure about that.

Which is probably the case. If you look at the description of HDMI in Wikedia you will read that there is a strong probability that there may be an incompatibility between the monitor and the computer: https://en.wikipedia.org/wiki/HDMI in particular the section :Personal Computers.

If the sound is going through HDMI then the Video card that is outputting the HDMI signal will also be treated as the sound card. Given it is just forwarding the digital audio signal via HDMI it shouldn't be doing much processing though. Another thing to check is that your playback sample rate isn't too high and matches one that can be sent over HDMI otherwise your sound card is having to convert the digital signal which it may not be good at. I don't know how to check / set that with pulse audio though. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adelaide Australia, UTC+10:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B

Of course it is a workaround. But the fact that applications have those workaround means that the problem is common. Another workaround: it is possible to view youtube in external apps; sometimes directly, some times indirectly (download the youtube video and play it in a player). -- Cheers / Saludos, Carlos E. R.

It should not. Maybe you need to change audio device inside your desktop configuration tool (system settings ?). Daniele. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Tried a lot also System Settings, even installed and played with jack (could not make it run), but without PA I have no sound at all. In System Settings I only have Default as the only sound device, which does not produce any sound using the Test button.

This is likely correct, ither because they used a intel audio chip on the graphics card or because the audio chip they created has the same interfaces as the intel one.

These are settings in Pulse Audio not your monitor, you want to try a much lower bitrate and or sample rate.
Besides, there was a suggestion to delay sound, but the problem is that the sound is about one second later than what is on the screen. Mouse movement on the screen is in sync with moving the mouse. The only solution is to have the sound processing faster.
Modifying your audio settings in Pulse audio is likely to speed up audio processing. similar to how modifying video settings in a game for example can speed up video processing. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adelaide Australia, UTC+10:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B
