1803721 - Media audio levels directly modify pipewire audio levels

Status: UNCONFIRMED

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

Description

[Matthew Warren]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:107.0) Gecko/20100101 Firefox/107.0

Steps to reproduce:

1. Open a youtube video
2. Open your audio mixer (For me it's the KDE Plasma audio settings
3. Adjust the youtube video volume and watch the value in the audio mixer change with it

This also happens with twitch, so you can use a twitch stream or probably any website that plays audio.

Actual results:

Firefox is directly modifying the pipewire audio level for the particular stream instead of using it's own internal volume parameter.

Expected results:

The volume in the system's audio mixer should NOT be changed by firefox. This is mainly problematic when raising the volume of the specific media source above 100% and then interacting with it in any way since firefox resets it back to 100%.

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.

Curious about how we're using pipewire, over to triage for discussion.
