How can we help you today?Due to Android system security and DRM (Digital Rights Management) policies, some third-party apps prohibit external software from capturing their audio stream.
Key Reasons:
System Privacy Restrictions: To protect user privacy, Android defaults to preventing third-party apps from recording system-level audio.
App-Level Limitations: If the source app (e.g., Netflix, YouTube, or banking apps) has not enabled the "Allow Audio Capture" permission, vCast cannot transmit the sound.
