Status: RESOLVED INCOMPLETE

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

Description

[guy]

Attachment: greyed out options

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

Open a site that plays video with audio e.g (https://www.youtube.com/watch?v=jNQXAC9IVRw)

or just audio e.g. (https://audionautix.com/Music/AcousticRock.mp3)

Actual results:

youtube video plays without the sound.

for audio files, I get errors dumped in the web console:

Media resource https://audionautix.com/Music/AcousticRock.mp3 could not be decoded.

and

Media resource https://audionautix.com/Music/AcousticRock.mp3 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_MEDIASINK_ERR (0x806e000b)
Details: OnMediaSinkAudioError

Also, when i right-click audio the play, mute, and speed options are greyed out as seen in the attachment for some reason.

Expected results:

video plays normally.

audio plays normally.

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