How do I enable a podcast feed for a discussion in a course?
You can insert a podcast feed for your discussion topics. A podcast is a way to distribute digital content for download on the Internet. A podcast feed is the file you use to distribute your discussion for users who want to subscribe through external podcasting channels.
Note: The Record/Upload Media Comment tool in the Rich Content Editor must be used for updates to be added to the podcast feed. Text-only discussion posts are not included in the feed.
Select Discussion Options

To enable a podcast feed for the discussion, select the the Enable podcast feed checkbox.
Include Replies in Podcast

Click the Include Replies in podcast feed checkbox to include the replies of students in the podcast feed.
Save and Publish

If you are ready to publish your discussion, click the Save & Publish button [1]. If you want to create a draft of your discussion and publish it later, click the Save button [2].

When your discussion is saved in a draft state, you can return to the page and publish it at any time by clicking the Publish button in the classic Discussions interface [1] or the Publish icon in the Discussions Redesign interface [2].
