AMD A4 won't play bit perfect?

I have been using Toshiba laptop (AMD A4 1.5 GHz 6 G Ram) as my core and Surface Pro 3 as remote with Emotiva DC-1 DAC with USB 2 drivers installed. I had exclusive mode and event driven selected on the remote and (usually) got bit perfect playback.

But with the DAC attached to the Toshiba, I get “Transport: Playback has failed due to parameter negotiation with the audio device” message and no playback. If I disable exclusive mode and even driven, I can get playback with the green quality light.

Is this because of the AMD chip, or is something else going on?

Audio drivers are your issue most likely.
