Resolution Note:
While we can reproduce this issue, and it is definitely a bug, it appears to be an Apple / iOS issue. There is no way for Unity to override the system volume or mute settings, so these should be respected by the device's audio system. Unfortunately, there appears to be a timing window where these settings are temporarily ignored.
Thank you for the bug report.
