Any TikTok sound generated from an originally uploaded video (not submitted as a separate audio) is not handled properly by our media pipeline. The issue arises from TikTok making a request for an `audio/mpeg`, while the server responds back with a MIME type of `video/mp4` and response body containing an `mp3` file. Downloading the file locally, you can see that renaming the file extension to `mp3` and opening it in Safari will play normally. A fix for this might involve inferring the type separately and falling back to that media type if the initial load is unsuccessful.

Modifying the source of that page so that the <video> element has a <source> tag with a 'type="audio/mpeg"' attribute causes the page to load correctly. <video class="" playsinline="true" x5-playsinline="true" webkit-playsinline="true" tabindex="2" mediatype="video"> <source src="https://v16m.tiktokcdn.com/9d1d39b4d82b9f45898221476afe4b7e/62f844a7/video/tos/maliva/tos-maliva-v-27dcd7c799-us/662ea36d360b41539e8b0fc113ebefc7/?a=1233&ch=0&cr=0&dr=0&er=3&cd=0%7C0%7C0%7C0&br=250&bt=125&ft=ApCEgBnZqq2mo0PZ9YyfkVQZ2TJw_KJ&mime_type=audio_mpeg&qs=6&rc=NDY2ZzZoZDQ8M2RnZDdkNUBpM2c0O2c6ZmpxPDMzZzU8NEAtLmM1YjMvNTYxYS0vL2M0YSNeLl5ncjRfYGRgLS1kMS9zcw%3D%3D&l=202208131840460101921662191132E5D9&btag=80000&cc=3" type="audio/mpeg"> </video>
May want to consider suggesting that workaround to TikTok.
