  for the Maestro 2E on the toshiba 2595xdvd worked. Since then either the c=
 ard has not worked or in this case since 5.x and now 6.x the card "works" b=
 ut there are no devices in the mixer so you have no volume.

 Many of these onboard codecs do not have a mixer device. Volume
 control was done in software, and an emulated 'mixer' pseudo-device
 was created. In the updating an mpsafing of code for version 5, this
 feature was lost.
 Ariff Abdullah <skywizard-at-MyBSD.org.my> has recently reimplemented
 this feature, and patches are available at
 http://staff.mybsd.org.my/skywizard/FreeBSD/sound/
 
 I have not tried any of them, so cannot say whether they will work
 with your hardware, or how to use them.
