Need infinite playback for art installation. Help please!

Hello all,

I have a relatively simple project that I am having a great struggle with implementing successfully.

The project:

A sculpture in a public place. Audio is coming out of the sculpture. Audio needs to play forever without stopping.

The setup:

Audio device(iPod) --> amp --> speakers

amp powered on/off with a timer.

The problem:

Audio device is an iPod which I tested at home for about 36 hours with uninterrupted playback. However, out in the wild, the device seems to shut off after an undetermined amount of time.

My question:

Is there a playback device that will repeat a single track of audio uninterrupted and indefinitely without requiring someone to push play? Something that won't shut off automatically? Something that can be started and not monitored?

Any help and suggestions are greatly appreciated, thank you!

This is probably your best bet, though I don't think you're going to figure out "infinite playback".

I don't want to invest more time and money into something i am not sure will work. I would do Raspberry Pi if I was 100% sure it would work.

Yeah, i guess a laptop would not shut off automatically, I'll look into that. I guess I was imagining something simpler.

"Infinite Playback" Lol, I didn't mean literally infinite. Reading that now is amusing. haha.

Thanks for all of your responses!

Instead of going shopping, I would be investigating why it will p-lay for 36 hours non-stop in your house, but not outside your house.

Did you change any settings?
Does it have an auto-power off function? Did you have it attached via usb in your house?

ps there are dozens of apps/programs that will allow you to put a device to sleep at a set time then wake that device at a set time playing a music file (looped).

A cheap tablet (Amazon Fire for example) would be better than a cheap laptop.

I have an old netbook lying around that I'm going to use. Any suggestions for apps?

What OS is the netbook running?

If it's Win 7 or better then you could just use the Task Scheduler to create the tasks you need.

You can wake the computer from hibernate (less power draw than sleep) at a set time, then have it launch your music file with WMP.
WMP remembers the 'loop play' button's last setting, so leaving it on loop will mean it stays on loop through the hibernate/wake cycles.
Then a task that puts the netbook into hibernate at the end of the day, then repeat the process.

I read an article that recommends you disable hybrid sleep mode before you set it up, as otherwise this might interrupt the wake cycle.
(run a Command Prompt as admin, then type powercfg -h off and hit enter.

Or use an app to control the sleep/wake timer like this:
http://windowsreboot.sourceforge.net/ and then just use the Task Scheduler to run the music file.
(When you create the task, for 'Action' choose 'Start a Program' but then select your music file instead of the music player .exe).
