Hi Team,
Customer is using TAS2557.
Would you please provide your comment for this?
When issue happened, TAS2557 will always check safe guard failed result in no sound.
Customer meet the same issue on google Pixel2, so there is solution which is also already mainline in TI codebase.
Below is git message of the solution.
Because the solution is doing HW reset to recover, customer want to know why TAS2557 meet this kind of error and is it possible to fix.

2. update error check in I2C transactions.
