You can access such experimental option via Settings -> Safari ->Advanced -> Allow speaker device selection, as seen in the below screen capture. There is no guarantee this will work, and maybe it will be enabled by default in the future.
There are some other experimental options as well that you can enable on iOS, such as AV1 and H265 codec support, and perhaps in the future Screen Capture will work, too. iPadOS tends to have more functionality available, such as external USB video device support (as of iPadOS 17), as least compared to the iOS 16 at time of writing. ![](https://2943598173-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MZHXv1G8N0MDxwotaT9%2Fuploads%2FGcknojwxuTe7KAmbIllB%2Fimage.png?alt=media\&token=e4c61973-c9d7-4006-9f48-e71d5ed14a09) ![](https://2943598173-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MZHXv1G8N0MDxwotaT9%2Fuploads%2FesjlMrvhGjSVUvpyIu4U%2Fimage.png?alt=media\&token=602314c4-e12a-42b7-9e37-4f04d054da3c) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.vdo.ninja/common-errors-and-known-issues/cant-select-audio-output-on-ios.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
