This is test for the Loopback driver, so it may make sense to rename the main source file from pcm.c to pcm-loopback.c or so. Or create a more universal code which allows to pass the card number/name by user.
Possible improvement (maybe for future update): Add a time check for the I/O operations using the system clock.
