    The same game in Windows plays back music just fine, but in WebGL when I walk (arrow keys) I get slowdowns.

    Play Windows
    Play WebGL

    Tried different Audioclip import settings - didn't help. Using Firefox.
    Updated to Unity 5.1.3 - didn't help either

    The way that moving around changes the pitch of the sound indicates that there is some bug in WebGL doppler effect simulation. This is possible, as WebGL uses different code for audio then other platforms. I'm not aware of any current issues in WebGL doppler effect simulation (but there have been some in the past). If you file a bug report with a project folder (and quote the case number here), I'm sure we can find a fix quickly.

    Hi, i had the same issue on webGL builds when playing sounds and having the camera move at the same time.

    I found a fix, put the "doppler level" of the audiosource linked to the sound, to the value of 0, i hope this helps :s

    FYI, we found the source of this issue (Doppler effect simulation is not correctly disabled when setting "spatial blend" to 0 on WebGL). This will be fixed in 5.3, until then, the workaround described by @AnonDreamer is fine.
