This likely indicates\ncontroller has lost sync between the streams, and we have to reset\nplayback.\n\nThere's no way to do this properly. The ISO-over-HCI transport is badly\nspecified in Bluetooth Core Specification.  Many controllers have broken\nimplementation of the current send timestamp read command, so packets\nhave no identifiers which ISO interval they belong to.\n\nControllers try to reconstruct the right interval based on\nmanufacturer-specific heuristics probably based on packet arrival times.\nKernel + USB introduce timing jitter, and playback sometimes desyncs and\npacket from some streams are persistently sent some multiple of the SDU\ninterval off from the intended timing.\n\nTry to determine this from packet completion latencies.
