	man play

BTW the hard coded voice setting of 0x0040 in hstest can be ignored, if
you now what you are doing. If it is set to 0x0060 (default) the audio
file must be converted to .sw and hci_usb driver must use ISOC alternate
setting 2. I am working on a new version of hstest which calls sox by
itself with the correct params according to the current voice setting.
