This is an iPHONE 3gs device issue very weird, but I took the code from KS for the sound_remote.js added my own URL to an MP3 file, and it works great ... on the iPHONE simulator. When I run it on the device, ( 3gs )... no sound at all, UNLESS i add speakers to the sound jack. Then it sounds great again.
So for some reason, I can not get the sound to play on the phone by itself. another issue, I have other radio players that work with out the external speakers on my 3gs phone.
I am looking at: Ti.Media.createAudioPlayer(); and I don't see a way to increase the volume.
I have not tested on android yet... but will try that next.
