Javascript audio playing at specific times of day, and randomly choosing from a number of different audios

I am working on a website for a friend, just about to apply audio, and have setup this test page to figure it out first.

So the idea is that at specific times of day (9 - 9.05pm, 8.55 - 9am, etc), if you refresh the page, a short audio piece will play once.. this audio piece will be randomly selected from a selection of 2 or 3, with a 'blank' track in there, so sometimes it will be silent. If you refresh again within the time slot another audio will play.

Here is the code..

AUDIO TEST !<br />
<br />
Chapel Bedroom @ 8.55 - 9pm<br />
Amazing Song, woodblocks + blank<br />
<br />
Jenny&#39;s Room @ 9 - 9.05pm<br />
Snow, Still a writer + blank<br />
<br />
Kitchen @ 8.55 - 9am<br />
Goosebumps, Rain, Reservation Piece + blank<br />
<br />
Living Room @ 2.05 - 2.10pm<br />
Flute and hidden voice, peacocks, whiterose + blank

So it is working on my side, but my friend said it is not playing for her on her side. Where am I going wrong ?

Thanks !
