Thanks for the tip. I tried polling rates of both 500 and 250 Hz, but I still receive the disconnect sound. I went ahead and submitted a ticket regarding the issue and included the logs.
I'll go ahead and mention here that the logs do contain multiple "Failed to open device..." and "Cannot find path for manifest key..." errors. I listed a few snippets from the log below.

I'm open to trying any other ideas you might have while awaiting a response through Corsair's support ticket mechanism.
