2018943 - Application audio volume resets while playing YouTube videos

Status: RESOLVED DUPLICATE of bug 1422637

(Core :: Audio/Video: Playback, defect)

Description

[doug.hs]

Attachment: Screen recording showing how the app volume resets

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:147.0) Gecko/20100101 Firefox/147.0

Steps to reproduce:

1. Open any YouTube video (e.g. https://youtu.be/JTm1aClf-fg?si=a0qhrapQkr6ynLzn).
2. Hit Play and watch the application-level volume on the system panel (it should be set to ~50%).
3. Correct the volume in the app-level controls, as the current volume is way too low.
4. Use the video seek bar to switch to another point in time, and watch the volume level again. The same behavior should be observed when switching to another video.

Actual results:

Volume will always reset to about 49%, ignoring my previous selection.

Expected results:

Application volume level should either reset to 100% or remember my last selection.

I cannot reproduce this on Chromium. I'm running openSUSE Tumbleweed and Firefox 147.0.4 (64-bit) packaged by the distro. I was instructed to report this upstream. See the downstream bug report [1].

I cannot reproduce this on any other sites I've tested so far: bandcamp.com and vimeo.com.

Actually, this might be a duplicate of [1]. I couldn't find it the first time I was searching for similar issues.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
