Hi,
I would like to use the JAZZ16 (PRO SONIC 16 FD-SCSI (650-0087-03) together with a MT-32 but the Mixer in DOS (to set the line-in volume) seems not to be able to retain the setting. After each reset, the volume of the line-in is again at 0. Does anybody know about this issue. I took the drivers for the Jazz16 from Vogon Drivers. Maybe there is a better mixer utility out there. These are all the resources I could find about the card:
