+  * $Log: sound_alsa.cxx,v $
++ * Revision 1.21  2004/10/18 11:43:39  dsandras
++ * Use Capture instead of Mic when changing the volume. Use the correct mixer when using the Default device.
++ *
++ * Revision 1.20  2004/10/14 19:30:16  dsandras
++ * Removed DMIX and DSNOOP plugins and added support for DEFAULT as it is the correcti way to do things.
++ *
++ * Revision 1.19  2004/08/30 21:09:41  dsandras
++ * Added DSNOOP plugin support.
++ *
++ * Revision 1.18  2004/05/14 10:15:26  dominance
++ * Fixes direct opening of sound output devices. The list of devices does no longer return NULL in that case. Patch provided by Julien Puydt <julien.puydt@laposte.net>.
++ *
++ * Revision 1.17  2004/04/03 10:33:45  dsandras
++ * Use PStringToOrdinal to store the detected devices, that fixes problems if there is a discontinuity in the succession of soundcard ID's. For example the user has card ID 1 and 3, but not 2.
++ *
+  * Revision 1.16  2004/03/13 12:36:14  dsandras
+  * Added support for DMIX plugin output.
