It's POSIX shared memory used for transfer data between PulseAudio clients and the server. Each client and the server own one of these segments and place data in there they want other processes to access. It's a sparse file. Usually only the first blocks are used. Use "du" to learn how much actually is used of the 64M pre-allocated. Note that the size of the file is misleading. Due to the way modern memory managers work that size is more of an upper limit of what could be used, only the value shown by "du" is actually taken up.
