Yesterday I tried to get it to work. The attempt had no positive results.

After trying everything I tried before, I downgraded the unit to Version 3. I put in a AB DSP card, and I changed the jumpers on the CD DSP card for a v3 version.

The unit worked like it should. Builing a configuration file in the legacy program, loading it and the unit worked like it should. Except there was no roomcorrection noise.

I upgraded the unit to v4, retyped it, made a new configuration file, and again no sound with room correction

All cards work, the unit is in pristine condition. There are no card errors at all.

The only thing I can think of is that it is in the software on the laptop. But I have the latest version of the configuration program. So that is just fine, leaving me with the one and only question I can't find an answer to at the moment.

WHERE DOES THE ROOM CORRECTION SOUND COMES FROM?. Is this sound produced by the 861, or is the laptop creating the sound. If the laptop creates the sound then that could be a possible problem.

The laptop works like it should, but what if the laptop can't produce the sound throught the USB port. Then I have to find another laptop to try it.
