What is the absolute fastest that sound can travel, and in what medium can it obtain that speed?

It is generally thought that the upper limit on the speed of sound is 57% the speed of light, which is the speed that sound waves travelled through the primordial plasma of the universe leading to baryon acoustic oscillations. However it may be the case that inside neutron stars there is sound faster than this.
