We found in this case serious noise problem happens. Log as follows with your patch <6>[ 175.960387][T401365] __uac_clock_find_source: Clock Selector 0xc has pin 2 selected <6>[ 175.966980][T401365] __uac_clock_find_source: Clock Selector 0xb has pin 2 selected <6>[ 176.026251][T400354] __uac_clock_find_source: Clock Selector 0xc has pin 1 selected <6>[ 176.032406][T400354] __uac_clock_find_source: Clock Selector 0xb has pin 1 selected There is no noise and I think this should be a firmware bug.
