Everything fine until here.

Should work with 'options  INSECURE' in config file, too (AFAIR)

Since the audio device is a loadable kernel module, the device
number is allocated dynamically from the next free slot.
Under 1.1 this used to be 25, but now there is another device
configured under that device number (tape driver?).

You can see that the device is loaded under number 26 (Off field).

Just change MAJOR=25 to MAJOR=26 in the MAKEDEV script of audiosrc11.

Yes, me. Well, rather trying than working.
Wrote a hardware driver for the audio device, which isn't working yet....
