Bluetooth audio latency issue & feature request

django

Not sure if this is a bug, but I am unable to adjust my latency to the positive side of 0. start at 0 and can only go negative. I wind up having to hardwire my headphones to have in-sync audio.

In addition I would request that this control be adjustable while watching video.

Sorry for the late reply.
What VR device do you use please?

django but I am unable to adjust my latency to the positive side of 0

Yes this is designed by this way.
When you set -0.2 then the audio would be adjusted 0.2s backwards which catches up with the image.

I am using the Quest.

in regards to the sync, I need to go in the opposite direction +0.2 to catch things up.

Firstly, Quest does not support bluetooth headphones hence this feature should not be used on Quest.
(Bluetooth headphones is known to have significant latency hence Quest officially does not support it. The option of "Bluetooth" in "Experiment" is only intended for Gamepad and Bluetooth keyboard".
We will remove this feature from Quest version in the next release.

Secondly, +0.2 means that your audio is actually ahead of the image.
Suppose the image starts at 0:00 and the audio with its latency starts at 0:02, then you need to adjust the audio -0:02 to catch up with the image.

Hope this info helps.

I don't care if bluetooth is experiemental (either it works or it doesn't-that's fine).

What I care about is that I need the OPPOSITE audio controls of what you are describing. +0.2 is what I am looking to do (audio needs to catch up), not -0.2 (audio needs to slow down). Currently I cannot go past 0 on the positive side.

django +0.2 is what I am looking to do (audio needs to catch up)

In SKYBOX, when you apply -0.2, the audio will catch up with the image.

But I'm looking for the opposite.

What we designed for "-0.2" should be what you looked for "+0.2".
Please try with it.

To reiterate: on Quest and Quest 2, we need to be able to set the default Bluetooth audio sync to a positive value (+0.2) in order to correctly match playback. The controls currently only allow a negative value, which just makes synchronization worse.

We can work around this changing the track setting's synchronization, but then have to reset it for every single video.

Please change the Bluetooth audio sync UI to support positive values, as that is the entire purpose of the feature.

I'm on an Oculus Quest 2 and would also appreciate this being fixed.

I have the same problem on my Quest 2，it should be set "+0.1s" or "+0.2s" to sync the audio and video.
