Re: AC97 system integration

Any idea why "The Wishbone clock must be at least 2x bit_clk_pad_i"?

I had noise problem with my own AC97 controller on LM4550: when I had speaker and headphone both plugged, the speaker output is ok. But when I unplugged the headphone, the speaker output because noisy instantly; The heaphone output was always noisy regardless whether the speaker is connected or not.
