From 9989fc25deb22ba1dde0ad6c30d34e1aff1931ed Mon Sep 17 00:00:00 2001 From: "Gabriel M. Beddingfield" Date: Wed, 8 Feb 2012 16:19:05 -0600 Subject: tinycap, tinyplay, tinymix: Add extra parameters. Command-line arguments are added for: tinyplay and tinycap: -D n -- card number -p n -- period size -n n -- number of periods per buffer tinymix: -D n -- card number Signed-off-by: Gabriel M.
