As per SSI IP needs external clks AUDIO_CLK1 and AUDIO_CLK2. AUDIO_CLK1 is provided by versa3 generator and AUDIO_CLK2 is provided by Crystal. Currently AUDIO_CLK2 it reports a frequency of 12288000 which is a multiple of 48kHz whereas for AUDIO_CLK1, it reports a frequency of 0. By defining the node, it will report as the value as 11289600 which is a multiple of 44.1kHZ.
