I'm loading mp3 files via a URL to the music file uploaded into WordPress.
I cannot use a plugin for this because I am doing this inside an imap.
The files load and play correctly, however, I am looking for a method of pre-setting the volume by adding a parameter in the URL.
What I have: href="http://mysite.com/wp-content/uploads/music/myfile.mp3"
What I want: href="http://mysite.com/wp-content/uploads/music/myfile.mp3 volume="0.4""
Does anyone know what HTTP parameter exists to pre-set mp3 audio volume?
If yes, can you provide me an example?
