Thanks to the person who encouraged me to reinstall the
sound driver. Had some resistance to doing that but I
finally worked out how to do it on WindowsXP without having
to dig out and search the four manufacturers start up CDs.
That seemed to do the trick. Volume slider works and
not only that but bot MJ-Slider and System Sound slider
move in harmony.
The remark about Totalrecorder is valid also. As soon
as I reinstalled the sound card, Total record insists
that the program is not installed properly. It seems
Total recorder does interfere at with the correct
operation of the sound card.
This is not a hassle though, because I hardly use Total
Recorder at all and am willing to intall and uninstall
as desired.
The whole sound interaction stuff in Windows seems
dated and does not correspond to the music/multimedia
capabilities of modern PCs anymore.
