Very Computer

Hi,

I could not get my Ensoniq Wavetable Sound Card to work in RedHat Linux
5.1 (even though it worked fine in 4.2).  So I got a Soundblaster 16
card and installed that instead.  It's wokring better, but it's still
not quite right.  I can play CDs fine, but I can't seem to get any other
sounds (Doom, RealAudio, .wav files, etc.) to work.  For those other
sounds, I get a variety of error messages suggesting that the IRQ and/or
DMAs are not properly set.  I used RedHat's sndconfig to configure the
card.  In Windows (where everything works fine), the settings are:

        I/O Port - 220
        IRQ - 05
        DMA - 01
        DMA - 03

In the sndconfig tool, it's impossible to choose DMAs 01 and 03 at the
same time--for the 8-bit DMA, I can choose 0, 1, or 3, and for the
16-bit DMA, I can choose 5, 6, or 7.  I have tried it with the 8-bit DMA
as both 1 and 3 (with the 16-bit DMA as 5 in both cases), and I've had
the same problems in both cases.

Do I have to recompile the kernel?  And if so, exactly which options do
I choose?

Thanks,
Morgan

Time for you to get your hands dirty...

IIRC, sndconfig configures things in /etc/conf.modules. my entries for
the soundcard looks like:

--------------------------------------------------------
post-install sb /sbin/modprobe "-k" "adlib_card"
options sb io=0x220 irq=5 dma=1 dma16=3 mpu_io=0x330
options adlib_card io=0x388     # FM synthesizer
--------------------------------------------------------

Run sndconfig and then open the file to see what and where it put the
module configurations. then just change the 16-bit dma to 3, and the
8-bit dma to 1, and save.

If the tools don't do it, do it yourself :)

Okay, sndconfig changes two files:  /etc/conf.modules and
/etc/isapnp.conf.  I changed my /etc/conf.modules from:

----------------------------------------------------------
alias sound sb
options -k sb io=0x220 irq=5 dma=3,5
alias midi opl3
options -k opl3 io=0x388
----------------------------------------------------------

to:

----------------------------------------------------------
alias sound sb
options -k sb io=0x220 irq=5 dma=1,3
alias midi opl3
options -k opl3 io=0x388
----------------------------------------------------------

. . .but that alone hasn't solved the problem (after rebooting, etc.).
I have no idea what to do with the /etc/isapnp.conf file.  It looks like
this:
