-OPL3-SA1 sound driver (opl3sa.o)
-
----
-Note: This howto only describes how to setup the OPL3-SA1 chip; this info
-does not apply to the SA2, SA3, or SA4.
----
-
-The Yamaha OPL3-SA1 sound chip is usually found built into motherboards, and
-it's a decent little chip offering a WSS mode, a SB Pro emulation mode, MPU401
-and OPL3 FM Synth capabilities.
-
-You can enable inclusion of the driver via CONFIG_SOUND_OPL3SA1=m, or
-CONFIG_SOUND_OPL3SA1=y through 'make config/xconfig/menuconfig'.
-
-You'll need to know all of the relevant info (irq, dma, and io port) for the
-chip's WSS mode, since that is the mode the kernel sound driver uses, and of
-course you'll also need to know about where the MPU401 and OPL3 ports and
-IRQs are if you want to use those.
-
-Here's the skinny on how to load it as a module:
-
- modprobe opl3sa io=0x530 irq=11 dma=0 dma2=1 mpu_io=0x330 mpu_irq=5
-
-Module options in detail:
-
- io: This is the WSS's port base.
- irq: This is the WSS's IRQ.
- dma: This is the WSS's DMA line. In my BIOS setup screen this was
- listed as "WSS Play DMA"
- dma2: This is the WSS's secondary DMA line. My BIOS calls it the
- "WSS capture DMA"
-
- mpu_io: This is the MPU401's port base.
- mpu_irq: This is the MPU401's IRQ.
-
-If you'd like to use the OPL3 FM Synthesizer, make sure you enable
-CONFIG_SOUND_YM3812 (in 'make config'). That'll build the opl3.o module.
-
-Then a simple 'insmod opl3 io=0x388', and you now have FM Synth.
-
-You can also use the SoftOSS software synthesizer instead of the builtin OPL3.
-Here's how:
-
-Say 'y' or 'm' to "SoftOSS software wave table engine" in make config.
-
-If you said yes, the software synth is available once you boot your new
-kernel.
-
-If you chose to build it as a module, just insmod the resulting softoss2.o
