It seems to me that it might be worthwhile to zero the volume or set the mute bit on the output channels just before closing the device. I started looking into this but haven't found the right place to insert the code yet. Anyone else have any ideas? Will this even make a difference? -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
