---------------------------------------------------------------------- port = (unsigned long)(vortex->mmio+VORTEX_MIDI_DATA); May be change "int port" to "unsigned long port" will fix the oops , can any EM64T or AMD64 user confirm about this ? ---------------------------------------------------------------------- Raymond - 05-21-06 04:16 ---------------------------------------------------------------------- MMIO is preferred when you are using au88x0 with other sound cards or snd-mpu401 (onboard superio chip) The following code allow the au88x0 driver to select I/O ports by varing the bits in CTRL_MIDI_PORT when VORTEX_MPU401_LEGACY is enabled, I only test on my au8830, /* Enable Legacy MIDI Interface port: 0x300, 0x310, 0x320, 0x330 */ port = 0x330; hwwrite(vortex->mmio, VORTEX_CTRL, (hwread(vortex->mmio, VORTEX_CTRL) & ~CTRL_MIDI_PORT) | (( port & 0x030 ) << 1 ) | CTRL_MIDI_EN ); BTW, please update the sound card matrix to indicate that au88x0 support midi Issue History Date Modified Username Field Change ====================================================================== 02-09-06 08:33 ponchick New Issue 02-09-06
