I haven't, but have read many reports of this issue. I have read that usually enabling bass management on the SACD player will further attenuate the sub signal down, sending all the redirected bass from the other channels may cause the analog signal to be overdriven- thus it is cut by the player to avoid this.

There is a good thread over at AVSforum.com about this issue.
