(In reply to Michael Froman [:mjf] from comment #5)
> This isn't strictly RDD related.  However, webaudio decodes are processed in batches to limit the number of IPC calls to RDD.  The pref that controls the webaudio batch size is media.rdd-webaudio.batch.size.  I tried this on my linux machine and can repro the problem with the default pref setting (100), but it appears to work with the pref set to 60 (I just picked a lower number).  Lowering this setting directly affects the decode performance for webaudio, so it may require some trials to figure out a better setting.
