Web audio recording - microphone disabled during screen lock

[heimdall89]

I'm developing a web app that uses audio recording. The issue I'm facing is that when the phone locks after inactivity, Android shuts down the microphone, probably due to a security policy.

I'm not aware of any way to allow a website to keep the microphone on during a screen lock.

Is anyone aware of how to shut this behavior off, or work around it? I think a mobile app can probably do it, but I'm wondering if a web app can.

Thanks for your help!
