 The block and non-block options are used to change the behavior of
 opening the device file.

+As default, ALSA behaves as original OSS drivers, i.e. does not block

 This blocking behavior can be changed globally via nonblock_open

 The partial-frag and no-silence commands have been added recently.
 Both commands are for optimization use only.  The former command
