Greetings,
I understand your challenge with autoplay restrictions. I can create a simple HTML page for you that plays a sound upon page load, ensuring compatibility with Firefox and Chrome. Once you confirm its functionality, I'll provide you with the source code.
I have 10+ years of Experience with: Web-Mobile App Development, Responsive HTML5, CSS, JavaScript, Laravel, PHP, WordPress, Elementor, wooCommerce, SQA/Testing, SEO Services.
Let's have a quick conversation on the details to proceed further with this project.
Thanks & Regards Usama N
