[Resolved] Misty records silent audio files

If you’ve been recording audio with Misty, you may have run into a problem where some of the audio files you record are silent. We’ve been tracking this bug for a few weeks and have narrowed it down to an issue with the audio services running on Misty’s Android OS. The system attempts to protect the microphones by automatically disabling them when Misty plays audio louder than about 65% of her max volume. Misty’s microphones don’t come back online when she’s isn’t actively playing audio, which means she may not actually be capturing audio data when you tell her to start recording.

We’re working to release a fix for this in a future system update. In the meantime, you can work around this by using the Command Center or the SetDefaultVolume command (REST | JS) to set Misty’s playback volume to be lower than 65% of her max volume before you attempt to start recording.


Update 2020-01-07:

This issue is resolved by the Android patch released on January 7, 2020. This patch will not be installed automatically as part of an over-the-air system update. Instead, it must be applied manually, from a computer connected to the same network as your Misty II robot.

You can download the patch and find installation instructions in this post:
