Device registration (experimental)

When you sign in, Libation registers a virtual device with Amazon. Audible then ties download licenses to that device. The default is an Android emulator, which is required for Widevine.

Audible has been refusing licenses (License Denied / CustomerThrottled) for some emulator registrations even when the same title still plays in the official Audible app. If that happens, you can try an experimental registration, or import credentials from mkb79's audible-cli.

Changing this setting does not convert accounts you already signed in. Remove and re-add the account (or run login-external) after you pick a different profile.

Where to find it

Chardonnay: Settings -> Important -> Device registration (experimental)
Classic: Settings -> Import library -> Device registration (experimental)
CLI / Docker: DeviceRegistrationKind in Settings.json, or --device-registration on login-external. See Command Line Interface.

The three profiles

Setting value	Label in Settings	Widevine	What it registers
`CurrentAndroid`	Android emulator (default)	Yes	The emulator Libation has used for years
`RetailAndroid`	Android Pixel (experimental)	Yes	Same Android Audible app as the default, with a retail Pixel fingerprint
`Mkb79IPhone`	iPhone / audible-cli (experimental; no Widevine)	No	The virtual iPhone used by audible-cli

Leave the default unless downloads fail for titles that still work in the official app.

How to apply a new profile

Pick the profile in Settings (or set DeviceRegistrationKind / --device-registration).
Remove the account from Libation. Existing Amazon device records keep the old registration until you sign in again.
Add the account and sign in, or run login-external.
Scan and try the download again.

Importing an audible-cli JSON file with import-account is the other workaround: those credentials already come from audible-cli's iPhone registration, so you do not need to change this setting first.

Widevine

Use Widevine DRM only works when the account was registered as an Android Audible app (CurrentAndroid or RetailAndroid). The iPhone profile cannot use Widevine. If you need Widevine later, remove the account and sign in again with an Android profile.

Settings.json (Docker and CLI)

json

{
  "DeviceRegistrationKind": "RetailAndroid"
}

Accepted values: CurrentAndroid, RetailAndroid, Mkb79IPhone. Then remove the account and sign in again. login-external --device-registration Mkb79IPhone overrides Settings for that one sign-in.

If it still fails

Wait 24 to 48 hours: Audible also rate-limits heavy Plus use. See Daily download limit and Retrying titles Audible refuses. If the official app can play the title and a new registration still cannot download it, open a GitHub issue and attach your log.
