Chrome only Loading 6 HTML5 audio tags

Set the preload attribute of audio (and video) tags like this: <audio controls preload="none">

This way media files won't download on page load (think about mobile performance especially). When a user presses play the relevant file will download as normal.

By default, Chrome lets you download five or six files simultaneously because that is the default value in most Windows installations. If you need to download more than five files, Chrome places some of the target files in a queue and then downloads them as soon as one of the five slots becomes available. Chrome does not allow you to change the number of concurrent downloads within the application itself. However, by editing the Windows Registry, you can set the number of simultaneous downloads in Chrome, or any other Web browser, to any number you choose.

Solution: One trick you can use to increase the number of concurrent conncetions is to host your video files from a different sub domain. These will be treated as seperate requests, each domain is what will be limited to the concurrent maximum.

I think this problem can be fixed by setting attribute preload of audio tag to metadata.
