If soundblaster is already installed and working with Windows, then you leave it alone. OS X can't use soundblaster, but it should use your onboard card if you find the right kext for it. (I use the normal AppleAC97Audio for my Soundmax.) From there, it's a matter of dealing with the annoyance of switching which plugs the speakers go into. Every time you boot OS X, you need to plug them into the outputs from the integrated sound card, and each time you boot XP you'll need to plug them into the Soundblaster outputs on the SB 5.1 card.

This is what I did on my dual-boot system to use onboard audio in OSx86 and SB Audigy 2 in Windows with ease (it just requires one click on a switch to choose between the two signals):

 

I went to an electronic parts retailer and got the following parts (should not cost you more than 20 bucks):

 

1x 3-pin two-way 3-pin switch (9 pins total)

3x (female) audio jack for female 3.5 mm stereo plug

2x 3.5 mm (male) stereo plug to 3.5 mm (male) stereo plug connector cables

screened (!) dual-cord (stereo) cable; you only need about 20 cm

plastic case (11 cm x 6 cm x 3 cm)

some tin-solder

soldering iron

drilling tool (e. g. Dremel)

 

Installation: Cut the screened dual-cord cable into three 6 cm pieces. Dismantle at the ends, trim and twist the copper screening, dismantle the inner cords (at all 6 ends). Solder cable #1 to one audio jack (this will be the output for your speakers), using the two "metal wings" for the inner cords and the eye for the twisted screening. Solder the other ends on this cable to the center line pins of the switch (choose any order for the cords and the screening). Solder the other two stereo cables accordingly (same order / cord colors) to the remaining two pin lines (left and right). Attach the other two audio jacks to the remaining cable ends like you did before.

 

Now for the test drive: Activate onboard audio chip in BIOS (for OSx86). Leave alone your SB audio card - it won't be recognized by OSx86 anyway, so you can just leave it there in the slot when you boot into Windows. Plug in your audio cable connected to your speakers into the audio plug connected to the center pins. Connect the other two jacks to the audio out for your SB audio card and onboard audio out respectively. Boot into the different OSes and use the switch to check if the respective audio signal "gets through" to your speakers. If everything works, drill four holes into the plastic case, install the three audio jacks and the switch, close the case, done.

 

I actually used a 4-pin switch to let some LEDs indicate which input signal is online. To do this, I attached to the overhead pins two separate circuits using 2x 3mm LEDs (one red one green), 2x suitable (in terms of ohms) resistors, some single-cord wire. I didn't want to use a battery as power supply, so I used the 5 volts of a USB connection (just installed a USB type B jack into the plastic case and used a proper USB connection cable).

 

Don't know if this is of any help, but it sure is a convenient way to switch between the two audio sources (and it was fun to do all this soldering, hehe).

 

Besides, note that you need an AC97 compatible onboard audio chip (set to active in BIOS) and the AppleAC97Audio.kext file in your /System/Libraries/Extensions folder to make it work. In Windows, you should check in the audio preferences if your SB audio card is still chosen as the audio device for music playback (may have changed after onboard chip activation and recognition by Windows on the first subsequent boot).

Do you have drivers for the onboard sound in OS X?

 

 

I was having the same problem the first time i installed 10.4.3 when i removed the sound card

osx had sound-and if i remember corectly bios had an otion for onboard sound wich i don see now...

i might just take the soundcard out and use the onboard sound for systems that way i dont unpug anything.

 

also i will give Cortilein advice a try-sb ivesounds 1000x better then onboard

thanks for the suggestions.

 

if anything how would i load the sound drivers on mac os xx 10.4.3 wich ones do i need?

Onboard audio has no sound when an add-on sound card is inserted. Is it a normal behavior?

 

Yes, this is a normal behavior. When inserting an add-on sound card, the onboard audio will be disabled automatically while the add-on sound card will have top priority to generate sound.
