Subject: Strange issue with opl3sa2 driver under linux 2.4.4
Hi all,
I'm trying to get sound working on my laptop, and I'm having some strange
problems getting it work as expected, and I hope that you can give me some
insight. I have a Toshiba Libretto 70CT, which is one of the hardware
platforms that is mentioned as working in the docs... I CAN get sound out of
it, but only after a strange ritual...
I have to do this to get it to work:
#modprobe opl3sa2 io=0x220 mss_io=0x530 mpu_io=0x330 irq=5 dma=1 dma2=0
opl3sa2: Control I/O port 0x220 is not a YMF7xx chipset!
#modprobe opl3sa2 io=0x370 mss_io=0x530 mpu_io=0x330 irq=5 dma=1 dma2=0
opl3sa2: Control I/O port 0x370 is not free
opl3sa2: Control I/O port 0x370 is not free
opl3sa2: Control I/O port 0x370 is not free
#modprobe opl3sa2 io=0x220 mss_io=0x530 mpu_io=0x330 irq=5 dma=1 dma2=0
notice that I have to modprobe it FIRST at 0x370, it fails, then it will
insert into 0x220! I have verified all the settings through both the BIOS
setup utility and by dual-booting into Windows98.
This is with kernel version 2.4.4. Do you have any idea about why it is
acting so strange upon inserting? In /proc/ioports it lists 0x370 as belonging
to OPL3-SA3, and 0x220 is not listed, however 0x220 is
the address that it ends up working under both in Windows98 and Linux.
Thanks very much, I really hope you have some idea how to work around this
more elegantly (so that maybe I can boot and have sound without typing all
that junk!) If there's anything I can do to experiment around that would help
others, just let me know and I'll be happy to do it.
Thanks once again,
David
