Why every time I open the bitbook it auto quits

For now there isn't any way to import songs to Lips from an iPod Touch or iPhone, you can't even stream music for any other game.

I took the liberty of contacting the developer - Sega Mobile Games - about this issue. They report that they haven't had any other complaints about the sound issue prior to my report, and consider it an isolated problem.

Here is the relevant excerpt from their response:

...I am unfamiliar with the specifics of that potential bug, but am glad to hear that reinstalling seems to have resolved it for the person on that website. Given how long ago that was mentioned, and that I have not seen any reports of the issue, it was likely either an isolated problem or long-since fixed. Hope that helps!

Since you reported this a few years ago on your iPhone 4S with iOS version 5.0.1, If this issue is still occurring for you, I would recommend updating both your phone OS version and the apps themselves:

• The most recent iOS version (as of writing) is 8.0.4.
• Sonic the Hedgehog is now on version 2.8.0 as of Apr 29, 2015
• Sonic the Hedgehog 2 is now on version 3.1.4 as of Apr 29, 2015
• Sonic the Hedgehog 4: Episode 1 is on version 1.4 as of Aug 15, 2012

If the issue is still occurring after updating, please raise a ticket with Sega Mobile Games Support. Link them back to this question to help provide context.
