Sound Card Dest -> Weird noise

soylent.green · Post by **soylent.green** » Fri Apr 04, 2008 1:07 pm

The setup:
It's a very basic scope project with only one Pro-12 which is connencted to a mixer. I've connected pulsar mixer outs to a sound card dest module. The module has been configured to route to my "SoundMax HD Audio" card which is my mainboards built in audio card. I've set sample rate of sound card dest to 44.1kHz. The scope cards (2 * 6 DSP) are sync master with 44.1 kHz also.
Both scope and the built in sound card work well on their own. No Problems there.

The result:
What is played back from the sound card output is simply noise. It's hardly recognizeable as Pro-12 Sounds. It's somehow distorted with crackles added on top.

The questions:
1.) Has anyone ever made successful attempts to route to a Sound Card Dest module?
2.) Any hints for getting rid of the noise? Any configuration options?

Thanks for your help!

Why would you do that. It spells trouble all the way!

arela, I guess your right. It's just for the sake of convenience and has to do with my overall setup.
I think there must be a way to get this done without investing to much effort and getting a sever headache...
Any hints what could be wrong? Is it the soundmax soundcard. Do they have a problem in general in such a setup? Any help welcome!

The signal is converted out from your pulsar to a analog signal.
When you route it through the soundmax, the signal will be treated the way soundmax think mp3s will sound best (even a possible AD/DA with poor converters)
You will at best lose quality.

Don't think Windows accepts 2 soundcards at the same time.

There is a drivver, ASIO4ALL, that might work, but it could be more trouble
and if it works, you will get poor quality sound.

I tried ASIO4All with a onboard soundcard and a Creamware Noah.
It worked in one way. I could play the synth and monitor on a desktop soundsystem, but for recording it was more or less useless.
When i moved recorded files to my scopesystem, they was really bad

I have similar problem in past. Changing card to another pci slot fixed this.

it does. I sometimes feed the scope wave destination to audacity (put in record pause mode) just to listen to a scope synthesizer
with headphones connected to the sb live platinum I have still installed just because of the headphone preamp...

just did that 2 days ago when I installed reaper for the first time and listened to it's demo song. reaper to scope done via asio.
