use SSI1 to be I2S, i made a dummy sound card to force output audio, but the audio frequency is not 48kHz, but 49.6kHz. and blck is not 3072kHz, but 3172kHz.

where should i check, please give a advance, thanks.

and i change the ssi_clk parent from "pll3_pfd_508M" to "pll4_audio_main_clk" in arch/arm/mach-mx6/clock.c, got the same result.
