Oddity with ASIO/Windows Sound Mapper behavior

I have a project loaded with some pretty hungry Izotope plugins (Denoiser especiallY) that has exhibited very stuttery playback on the timeline.

I have been using the Maudio Profire Lightbridge as my audio interface consistently, and have had it selected as such in the Audio Device preferences tab, designating the SPDIF output as my main monitoring path.

I accidentally opened this project in a setup that had defaults setups and had selected Windows Sound Mapper as my main audio device, which leaves the selections for ports on the Maudio box greyed out.

Amazingly, all the stuttering disappears when I do this, and the audio still comes out of the SPDIF port on the Profire Lightbridge.

I am sure I have the latest drivers implemented for the Maudio box, but it has been discontinued. In any case, this does not seem like kosher behavior.

I am not a big Maudio fan, but had been using this box to gain inexpensive 32by32 I/O.

Would love feedback from Sony, or anyone out there that has a clue about this.

I see there is a new driver released in June that I did not know about......perhaps this will address the issue.

Going to check it out.

Well, that was a major bust......I installed the latest driver, and now I can't get SPDIF out of the Profire Lightbridge with Windows Sound Mapper enabled........All the settings that allow enabling of the Profire SPDIF stutter as always.

Big drag.

Any chance of plugging in another (maybe USB2) interface with ASIO to see if that works better ? Things sort of point to the Profire and it's drivers ....

It sounds like your ASIO device is also being used somehow as the default Windows sound card. You can prevent Windows from using this hardware and see if your problems are resolved.
