Please make sure the MUTE switch is not enabled on your iPad.
Papers, Please uses the OpenAL audio subsystem, which relies on the PULSE or ALSA sound libraries in Linux. The Debian install file doesn't list these as dependencies (probably a mistake). If your game plays but has no audio, try installing either PULSE or ALSA.
There are a few things to try.
Reduce your audio output settings
Some users have reported problems running the game if their audio output quality is set above 24 bit 96kHz. If you have a high-end sound card with adjustable output settings, try setting the output quality to 24 bit 96kHz or lower.
Disable all but one audio output device
Some users with multiple audio output devices have seen startup crashes that go away when disabling all but one of these devices.
Update your audio device drivers
- Open the Device Manager from the Windows Control Panel.
- Find your audio device, right-click on it and select "Update Driver Software..."
- Follow the prompts to search for an update online or install one manually.
