On some websites the embedded video will play but no sound. Here's an example. https://www.rte.ie/culture/2022/1026/1331602-surrender-by-bono-sinead-crowley-reviews-his-autobiography/ Direct link to video here https://cdn.rasset.ie/hls-vod/2022/1028/20221028_webexclusi-bonospeaks_c22165371_22165372_260_/manifest.m3u8 I have tried by turning off the ad blocker but that does not help. The video and sound play fine if I play the video on Google Chrome. It appears that the sound is off by default but if I try to click the mute button on the video nothing happens. Pls help Thanks
