Very Computer

Recently, I have installed Redhat 7.1 on my laptop
computer.
I find that it cannot play audio CD.

I have checked with Win98 setting. The audio
driver is OPL3-SAX WDM driver.

When I boot to Redhat Linux, the messages [dmesg]
are as follow:
****
opl3sa2: ISA PnP activated failed
opl3sa2: No cards found
opl3sa2: 0 PnP card(s) found.
****

After I login GOMONE as root, an error message appears
***
couldn't open mixer /dev/mixer
***

I have used [setup] to config the soundcard.
It looks like that it can detect & match the
ISAPNP sound card.
***
A ISAPNP sound card was found in your system.
The detalis are:
Model Yamaha OPL3-SAX Audio
System unknown.
***

But it fails to play any sound effect
***
Unable to play Audio
An error occurred opening /dev/audio
***

I have follow the config of Win98
such that the same audio setting is done in
Linux. But no use, still cannot play any
sound effect as before.
***
I/O   0X530
IRQ  5
DMA1  0
DMA2  1
MPU I/O  0X300
Control I/O 0X370
***

When I logout & reset, another error message
appears as follow:
***
error opening mixer
saving mixer settings: modprobe: modprobe: can't
locate module sound-services-0.0 [failed]
***

How can I fix the problem?

Thx

That looks like the driver, but it isn't loading. ISA PnP doesn't seem to
be working either. Couple of things you can try: 1) go into your BIOS and
if there's an option that says "Plug'n'Play OS", set it to No/Off -- that
way the BIOS itself will configure the devices, rather than leaving it to
the OS; 2) Go back to Win98 and get all the settings for the card -- IO
port, IRQ, DMA etc. In Linux, use those as command line options when
loading the driver.

Your kernel source will give you the command line you need to use. Looks
like: modprobe opl3sa2=<io>,<irq>,<dma>,<dma2>,<mssio>,<mpuio>
