As far I know, there is no way to play any sound on a webpage if the user did not first interact with the page.<p>But Big compagny video like TikTok or Youtube achieve to do it.
You can open a direct link to a TikTok video or a Youtube Short and it will play with sound without any click.<p>Does anyone know how they bypass the restriction ? Is it some kind of whitelist that the browsers implement ?
It looks like these websites are in a whitelist, see <a href="https://blog.google/products/chrome/improving-autoplay-chrome/" rel="nofollow noreferrer">https://blog.google/products/chrome/improving-autoplay-chrom...</a>
