Rmmod does (think it will) remove the driver. It will not, however, end the association of that driver with the sound card. Using the sound card configuring routine simply goes back to the erroneous maestro. If I manually change it, it exits complaining that the sndconfig entries are already there. All that is is an alias snd.... = maestro. I have two other devices around as well: 1. USB Roland MIDI. This appears to have been configured so I need some quick way of testing it out. Maybe I'll just start up rosegarden and see if it receives anything. 2. SW60XG ISA sound card. This uses no IRQ or DMA, just a settable port address. The card is supposed to be accessible using an mpu401 driver. How might I set this one up.
