iPod - USB dac. Possible?

phrarod · 13th January 2008, 02:28 AM

Is it possible to plug an iPod into a USB dac or does any extra processing have to happen? I'm not sure why I could plug a computer into a USB dac and drive it with iTunes and not an iPod with the data out pins.

Alpine is doing this with their new head units so they can use a 24-bit burr brown.

There is a USB Audio profile for which there is a standard driver on both Windows and OSX (and I'm sure others) which is why it "just works". To my knowledge, the iPod does not have such a driver.

Is there any hack to load such a driver?

Nope. iPod is an end point, so don't expect this to ever happen.

Thanks Dave. Now I understand what Alpine was mumbling to me at their booth at CES. If they had explained it like the article I would've got it.

There goes my idea for a new product.
