Firefox game intro is silent until you press play: compare autoplay with in-game audio

Firefox audio • Independent troubleshooting

Separate the intro from the game

A browser game may show an introductory video or music control before the table loads. Note whether the silence happens before you interact, after you start the game, or only on one control. If the page has an ordinary play button and you intend to hear the media, try it once outside a live round.

Look for Firefox’s site indicator

Mozilla says Firefox blocks automatically playing media with sound by default and displays an indicator when it is actively blocking media on a site. Record whether that icon appears. If the intro plays normally after you press play, that is consistent with an autoplay restriction. It does not establish how every sound in the game is generated.

Keep a narrow test

For example, a video introduction is silent when a page opens, plays with sound after a deliberate click, and card effects are still audible afterward. A player can retain quiet startup behavior and use the play control when needed. If both the clicked video and the game remain silent, note that result and check the game and device audio separately.

Preserve preferred site behavior

Review the current site setting in Firefox if you want a different behavior on that site. Keep your normal defaults for other pages. A useful help request states the browser version, whether a block indicator was visible and whether a deliberate play action changed anything. Avoid resetting the whole browser based on one intro video.
