Hello,
I am having an issue with the tlv320aic3110 codec. I get these two errors during boot up in my embedded device:
[ 10.079068] tlv320aic31xx-codec 0-0018: Unable to sync registers 0x1d-0x1d. -6 [ 10.161668] tlv320aic31xx-codec 0-0018: Failed to restore cache: -6
According to the datasheet, 0x1d can be "Table 7-69. Page 0 / Register 29 (0x1D): Codec Interface Control 2" or "Table 7-136. Page 1 / Register 1 (0x01) Through Page 1 / Register 29 (0x1D): Reserved".
After about a minute, there are also these errors:
[ 66.858820] tlv320aic31xx-codec 0-0018: ASoC: error at snd_soc_component_update_bits on tlv320aic31xx-codec.0-0018: -16 [ 66.943057] tlv320aic31xx-codec 0-0018: ASoC: error at snd_soc_component_update_bits on tlv320aic31xx-codec.0-0018: -16 [ 67.092200] tlv320aic31xx-codec 0-0018: ASoC: POST_PMU: HPL Driver event failed: -16 [ 67.383700] tlv320aic31xx-codec 0-0018: ASoC: error at soc_component_read_no_lock on tlv320aic31xx-codec.0-0018: -16 [ 67.482291] tlv320aic31xx-codec 0-0018: ASoC: error at soc_component_read_no_lock on tlv320aic31xx-codec.0-0018: -16 [ 67.545386] tlv320aic31xx-codec 0-0018: ASoC: POST_PMU: SPL ClassD event failed: -16 [ 67.823211] tlv320aic31xx-codec 0-0018: ASoC: error at soc_component_read_no_lock on tlv320aic31xx-codec.0-0018: -16 [ 67.895536] tlv320aic31xx-codec 0-0018: ASoC: error at soc_component_read_no_lock on tlv320aic31xx-codec.0-0018: -16
And finally, after suspend/resume, I get these last errors:

I have been trying to find a solution for a few days but I haven't been able to find anything important. Is there anything I could do to maybe get closer to the root cause of these errors? Has anyone seen something like this before?
Let me know if you need any other information from me that might help.
Thanks in advance!
