We have a problem with ADV7625, could you help us?
Audio input : input to R17(P15/AP2_IN0)
Format : SPDIF
It seems there is no problem with visual and audio. Audio data by SPDIF can be heard clearly.
But SPDIF_SF[3:0] register that can indicate sampling frequency from SPDIF doesn't seem to be read correctly(always 0).
What should we check?
Do we need something special settings?
Your advice would be most appreciated.
