Both the Alsa and OSS drivers for the Yamaha OPL3-SA2 don't work with kernel 2.4 on my laptop. OSS drivers work fine in kernel 2.2 so obviously somebody broke something along the way. I've tried both auto and manual configuration of the soundcard in the bios / using module options. All kernels have ISA-PNP compiled in.
When I've tried manual configuration, the following ports/irq/dma are used: With the OSS drivers: (this works in kernel 2.2 series only) -------------------------- insmod opl3sa2 io=0x100 mss_io=0x530 mpu_io=0x300 irq=5 dma=0 dma2=1 When I use the 2.4 kernel series, the module reports: kernel: opl3sa2: No PnP cards found kernel: opl3sa2: Search for a card at 0x256. kernel: opl3sa2: Control I/O port 0x100 is not a YMF7xx chipset! (This looks strange to me.. the YMF7xx is a PCI, not ISA sound chipset) Also, I thought ISA pnp devices are supposed to use the port range 0x203 to 0x3ff. In my laptop's bios, the only port selections for manual configuration are 0x 100,120,140, and 160. With the ALSA drivers (0.9.12) + kernel 2.4.18 / also tried 2.4.19-ac2 --------------------------- #options snd-opl3sa2 snd_port=0x100 snd_sb_port=0x220 snd_wss_port=0x530 snd_midi_port=0x300 snd_fm_port=0x388 snd_irq=5 snd_dma1=0 snd_dma2=1 The alsa driver reports: Yamaha OPL3-SA soundcard not found or device busy ---------------- No interrupts are being shared, IRQ 5 is free. My /proc/ioports looks like this: (note: I tried configuring the PCMCIA config.opts to exclude 0x100 - 0x600 for safety) 0000-001f : dma1 0020-003f : pic1 0040-005f : timer 0060-006f : keyboard 0070-007f : rtc 0080-008f : dma page reg 00a0-00bf : pic2 00c0-00df : dma2 00f0-00ff : fpu 0170-0177 : ide1 01f0-01f7 : ide0 0376-0376 : ide1 03c0-03df : vga+ 03e8-03ef : serial(set) 03f6-03f6 : ide0 0cf8-0cff : PCI conf1 1000-103f : Intel Corp. 82371AB PIIX4 ACPI 1040-105f : Intel Corp. 82371AB PIIX4 ACPI 4000-40ff : PCI CardBus #01 4000-407f : PCI device 10b7:5157 4000-407f : 01:00.0 4400-44ff : PCI CardBus #01 4800-48ff : PCI CardBus #05 4c00-4cff : PCI CardBus #05 fcd0-fcdf : Intel Corp. 82371AB PIIX4 IDE fcd0-fcd7 : ide0 fcd8-fcdf : ide1 fce0-fcff : Intel Corp. 82371AB PIIX4 USB fce0-fcff : usb-uhci Any help figuring this out would be greatly appreciated. I'm willing to hack on code, but I'd like to know if anyone else has resolved this issue or has a clue where to start.
