1602723 - Removing audio jack while in talky.io call will make the video/audio to be out of sync

Status: RESOLVED DUPLICATE of bug 1586370

(Core :: WebRTC: Audio/Video, defect, P2)

Description

[Bogdan Maris, Desktop Test Engineering]

Affected versions

• 72.0b4

Unaffected versions

• 71.0RC

Affected platforms

• macOS 10.13

Steps to reproduce

1. Have two people join a talky.io room
2. Have the person which is connected with earphones (jack) remove it

• I used MEMT T5 with mic earphones

3. Reconnect the earphones (jack)

Expected result

• Audio/video is back and in sync

Actual result

• Audio/video is off sync, a delay of 2-3 sec is introduced

Regression range

• Not sure if this is a regression or not, I will try and find a regression ASAP, it might take some time since I have to do it manually (can't use mozregression).

Additional notes

• Other operating systems are not affected by this (windows 7, ubuntu 18.04)

Happy to take a patch in 74, but since it has a priority assigned I'm marking it fix-optional so that we don't keep seeing it in weekly regression triage. Dan, do you think the see also issues might be duplicates?

It does sound that way. :bogdan_maris, if you have a chance, could you retest this to see if this has been fixed by Bug 1586370? Thank you.

I did retest this on Fx74 with the same setup as in comment 0 and I was unable to reproduce the delay.
Though a short delay of 1-2 seconds is present right after I reconnect the headphones which I assume is acceptable, since the OS needs that time to identify the headphones device.

Thank you for retesting.
