InvalidAccessError for some users only

[sersorrel]

The following error appears in the console whenever music should be playing, but only for some users. The exact start time differs between runs, even for the same user.

VM343:1 Uncaught InvalidAccessError: Failed to execute 'start' on 'AudioBufferSourceNode': The start time provided (-0.477551) is less than the minimum bound (0).

It happens when searching for myself and torvalds, but not ajacksified. Chrome 53, Ubuntu 16.04. Let me know if there's anything else I can do to help debug this.
