Lingoodie uses your device's built-in text-to-speech to pronounce words. If you don't hear anything, your speech engine is usually missing, turned off, or your volume is down. Follow the steps for your device.
Install and enable Google's speech engine
Install or update the speech engine: open the Google Play Store and get "Speech Recognition & Synthesis from Google" (also called "Speech Services by Google").
Open on Google PlayMake sure it's enabled: go to Settings › Apps, tap "See all apps", find "Speech Recognition & Synthesis" (or "Speech Services by Google"), and if it shows Disabled, tap Enable.
SettingsAppsSpeech Recognition & SynthesisEnableSet it as the default engine: Settings › Accessibility › Text-to-speech output › Preferred engine, and choose Speech Services by Google.

This is the most common cause when the basics are fine and you still get silence, especially on Samsung phones.
Your phone can have a speech engine installed but still be missing the voice for your course language (for example Portuguese or German). When the voice for that specific language is not downloaded, the lesson stays silent even though everything looks set up. The app can tell that an engine exists, but it cannot tell whether the individual language voice has finished downloading.
How to fix it
Tap the gear / settings icon next to your engine, then "Install voice data" (or "Languages").
SettingsAccessibilityText-to-speech outputSettings iconIf you now hear the example, reopen Lingoodie. Audio should work.
If the example is still silent, the problem is your phone's speech engine, not Lingoodie. Continue to the Samsung section or switch engines below.
This affects all Android phones, not one brand: Samsung, Motorola, Xiaomi, OnePlus, Pixel and others. The step above is the fix for all of them. Below are a few brand-specific extras.
Motorola and other near-stock Android (Pixel, Nokia, etc.)
These use "Speech Services by Google" with no separate manufacturer engine, so the fix is almost always just downloading the voice for your course language. On budget models like the moto g series the language voice is often not pre-installed, so this is the usual cause.

Samsung phones (Galaxy)
Use Google's engine, not Samsung's
The Samsung text-to-speech engine does not support every language. If your course language is missing or silent, switch the preferred engine to "Speech Services by Google" (install it from the Play Store first if needed), then download your language voice as above.

Samsung has a feature that can send one app's audio to a different device (like earbuds that are no longer connected). If Lingoodie's sound was routed there, you hear nothing.
SettingsSounds and vibrationSeparate app soundIf Lingoodie is listed, set it back to your phone speaker or turn the feature off.
All phones: check media volume
Press the volume button, open the menu, and make sure the Media slider (not just Ringtone) is up.
Quick test to know where the problem is
Use the "Listen to an example" button inside Settings › Accessibility › Text-to-speech output.
