We are using AC-97 controller IP in an FPGA connected to a SoundMAX codec AD1986. Using fixed sample rate of 48kHz an incoming audio signal is sampled well. If we enable variable sampling rate in the AC-97 controller the result is still okay at 48kHz. But if we are going down with sampling rate, e.g. to 41kHz, a few samples are given out isocronously by the controller with wrong values. The slower the sampling rate gets the more wrong values are given out. Who knows something about that problem?
