Revision 1.5, Sun May 2 11:54:26 2010 UTC (14 years, 1 month ago) by ratchov
Branch: MAIN
CVS Tags: OPENBSD_5_1_BASE, OPENBSD_5_1, OPENBSD_5_0_BASE, OPENBSD_5_0, OPENBSD_4_9_BASE, OPENBSD_4_9, OPENBSD_4_8_BASE, OPENBSD_4_8
Changes since 1.4: +2 -2 lines 

Clean up device handling code to clarify different initialization phases
and different device states. Split initialization in two phases:
first global variables are initialized then the audio hardware is opened.
Allow devices that don't support full-duplex to work in play-only or
record-only mode, even if ``-m play'' or ``-m rec'' are not specified.
