 While the default behaviour is to load sound data in full, it may also be beneficial to load the data in chunks, prior to their use. This is often called "streaming".
 
-One benefit is that the runtime memory is kept low.

-Another benefit is that, if you are streaming content from e.g. a http url, you can update the content at any time, and also avoid the initial download.

 ### Easy way
 
-The simplest way to use sound streaming, is by setting the `sound.stream_enabled` to true.
-By simply switching on this flag, your project will start streaming the sounds.

+You can of course use other means to load the initial chunk of the sound file. The important thing to remember is that the rest of the chunks are loaded from the resource system and it's resource providers.
 
 In this example, we have added a new file provider by adding a live update mount, by calling using [liveupdate.add_mount()](/ref/liveupdate/#liveupdate.add_mount).
 
 
 ## Sound chunk cache
 
-You can control how much memory will be consumed by the sounds at runtime, by setting the size of the "sound chunk cache".
-Given this limit, the loaded sound data will never exceed this limit.
-
-Some things to note:
-
-* Sound files smaller than the sound chunk size, aren't streamed.
-* If a new chunk doesn't fit into the cache, the oldest chunk is evicted
-* If the cache is too small, chunks may get evicted the same frame, and the sound won't play properly.
-
-The initial chunk of each sound file cannot be evicted, so they will occupy the cache as long as the resources are loaded.
-You can also control the size of each sound chunk. This may help you get the sound cache size down even further if you have many sound files loaded at the same time.
-
-## Configuration
-
-Currently, the streaming is enabled on all sound resources.
-We may improve upon this in the future, allowing settings on individual sound files.
+The amount of memory consumed by the sounds at runtime is controlled by the [`sound.stream_cache_size` setting](https://defold.com/manuals/project-settings/#stream-cache-size) in *game.project*. Given this limit, the loaded sound data will never exceed this limit.
 
-The game project supports these settings:
+The initial chunk of each sound file cannot be evicted and they will occupy the cache for as long as the resources are loaded. The size of the initial chunk is controlled by the [`sound.stream_preload_size` setting](https://defold.com/manuals/project-settings/#stream-preload-size) in *game.project*.
 
-* `sound.stream_enabled` (default 0) - If enabled, enables streaming of all sound files
-* `sound.stream_cache_size` (default 2097152 bytes) - The max size of the cache containing _all_ chunks.
-* `sound.stream_chunk_size` (default 16384 bytes) - Determines size of each chunk that is loaded from a file at a time
-* `sound.stream_preload_size` (default 16384 bytes) - Determines size of initial chunk read from each found file in the archive
+You can also control the size of each sound chunk by changing the [`sound.stream_chunk_size` setting](https://defold.com/manuals/project-settings/#stream-chunk-size) in *game.project*. This may help you get the sound cache size down even further if you have many sound files loaded at the same time.
