Check https://experienceleague.adobe.com/docs/experience-manager-cloud-service/content/implementing/content-delivery/caching.html?lang=en for finding out about cache control.

Which AEM version are you using? Also, is there any specific component in which you face the issue?

Thanks @Jagpreet_Singh_ & @kautuk_sahni for the recognition.

https://experienceleague.adobe.com/docs/experience-manager-cloud-service/content/assets/admin/developer-reference-material-apis.html?lang=en is helpful for Asset creation in AEM.

Can you directly open the system console and see the CQ link configuration?

It would be best if you embedded the jar as well.https://experienceleague.adobe.com/docs/experience-manager-cloud-service/content/implementing/developing/aem-project-content-package-structure.html?lang=en#embeddeds 

Check logs for any error.

Can you check if the file exists here:/content/dam/my-project/folder/audio/file.mp3 Also, see if the below URL is blocked in AEM as Cloud Publish: https://publish-pXXXX-XXX.adobeaemcloud.com/content/dam/my-project/folder/audio/file.mp3 

Can you share more details like Java, maven archetype, and maven versions?

Can you provide AEM version in which you are facing this issue?
