[Android] Internal Audio Capture Issue
Since around April 7, 2026, some Android users have been experiencing an issue where internal (in-game) audio is not captured while streaming with PRISM.
We have identified the root cause and want to share the details along with a temporary workaround.
What Caused This?
On April 7, 2026, Google released Android System WebView version 147 (release notes: https://developer.chrome.com/release-notes/147), which introduced a bug causing apps that use MediaProjection + AudioPlaybackCapture to receive only silence during audio capture.
This bug has been officially reported to Google and is being actively worked on. (Bug report: https://issuetracker.google.com/issues/505414470)
According to Google's plan, a fix is expected to be included in Android System WebView versions 148 and 149, which will be rolling out soon. However, the exact timing of the release is difficult to predict.
Temporary Workaround
Until the patched version is available, you can resolve the issue by following these steps:
Go to Settings > Apps on your device
Search for 'Android System WebView'
Tap the more options button (⋮) and select 'Uninstall updates', then tap OK
Open Google Play Store > Android System WebView > More options (⋮) > Turn off auto-updates
Reboot your device (required)
Launch the PRISM app and verify audio capture is working
⚠️ Once Android System WebView version 148 or 149 becomes available, you can safely re-enable auto-updates.
Alternative for Android 16 users
On Android 16, the option to disable auto-updates for Android System WebView is no longer exposed. If you cannot complete step 4 above, use the WebView Beta channel instead:
Install 'Android System WebView Beta' from Google Play (we recommend version 146, which predates the regression)
Open Settings > Developer options > WebView implementation
Select 'Android System WebView Beta'
Reboot your device and relaunch PRISM
We apologize for the inconvenience and appreciate your patience and support.
