Comment:

 Thanks for your report! A patch for the audio latency of Curtis’s phone
 has been added in commit 4a75fbab1b508f4240615c62811e2c8828534177 and will
 be available in daily builds 1.10.0git-4851 and later. As mentioned
 earlier with the videos, the delay before starting the videos is the game
 fading out ambient audio.

 This patch also addresses issues in other games (Lighthouse train power,
 KQ7 jumping rabbit at start of chapter 1) where the games restart audio
 samples on every frame, since we were rendering too much audio data which
 caused some looping audio artefacts that didn’t normally exist in the
 original engine.

 I was not ever able to reduce my Linux VM system audio latency so I could
 not verify this issue is addressed in Linux, but I ''was'' able to verify
 that the problem existed and is now fixed in macOS, so I have to assume
 that any similar issue on a well-behaved Linux machine will be fixed as
 well.
