I haven't heard of anyone else reporting this issue lately, so chances are there might be a local problem on your end-
please do check if one of the following things fixes your issue:
- please close & restart your browser, ideally dump the browsers cache or make sure the cached files are re-fetched by pressing CTRL+F5 key when arriving on wikiloops
- if that doesn't help, please reboot your computer to make sure it's not a hung up soundcard issue
If that doesn't do the trick, feel free to get back to me and let me know which browser / device you are using + your current location + the track IDs of not-playing tracks, that way it's much easier for me to dig into a more detailed problem spotting.
All the best
