Hi, @planetrambler
Welcome to the Roku Community.
We see that you have encountered an issue with the soundtrack of "Air Disasters Series," and we're here to help you contact the right support to address this matter.
Since this is an isolated case involving a specific channel and content, we advise you to contact the channel provider directly and let them know about the issue you have experienced. They may offer a potential workaround or indicate whether an update to their application on the Roku platform is required. It is important to note that the majority of channels available on Roku are developed and maintained by the respective channel providers.
We hope this will be sorted out soon.
