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

Are you sure it really fails when modprobing at 0x370 ?

Try to modprobe at 0x370 and immediatly look at the output of "lsmod" to see if the driver is really loaded or not ... ???

Merci beaucoup Jérôme! You are indeed correct, somehow you saw through my rantings, and although I thought I had tested everything extensively and scientifically, it does indeed work with 0x370...

Now I have an alias in /etc/modules.conf so that all I have to do is modprobe opl3sa2 and everything works... if you don't mind I'd like to ask a few questions about getting it a little more automated...

1.) any idea how to get it automatically inserted when I try to use the sound
card? (For ethernet cards I know you alias eth0 to the driver name, but aliasing dsp and sound to opl3sa2 don't seem to work)
2.) any ideas how to avoid the "opl3sa2: Control I/O port 0x370 is not free"
messages since they are apparently bogus?
3.) any ideas what to do to make it work when compiled into the kernel?
a line in lilo to pass parameters to the kernel?

Thanks again,

David

:-)

1) here is the part for the sound from my modules.conf file :

alias sound-slot-0 opl3sa2
options sound dmabuf=1
alias midi opl3
options opl3 io=0x388
options opl3sa2 mss_io=0x530 irq=5 dma=1 dma2=0 mpu_io=0x330 io=0x370 ymode=1

2) I don't know ... I also get the 3 messages about 0x370 not free, so I'll look into the driver and try to see what's wrong with the initialization ...

3) If you build the opl3sa2 directly into the kernel you'll need to add the "opl3sa2=<io>,<irq>,<dma>,<dma2>,<mssio>,<mpuio>" parameter to lilo.

Now I remenber ... try to use the isapnp=0 parameter to disable PnP detection and it should remove those messages when inserting the module.
