       The  "Device"  option under the keyer depends on the particular driver.
       The "default" setting picks the default sound device.  This option  may
       be used to pick a different soundcard than the default one.

       For  alsa, it is "hw:<card>,<device>", where the card and device number
       are  the  particular  hardware  devices.   The  default  is   generally
       "hw:0.0".   Generally  0 is the first card, 1 is the second, etc.  Some
       sound cards may have multiple output  devices,  the  device  picks  the
       particular one.

       For oss, sun, and aixs, it is the device name, like /dev/dsp.

       For esd, it is the host name, like "".

       It is not used on any other drivers.
