I have tried solving this problem and have had no solution yet. I am using the Razer Kraken Pro 7.1 headset I get the error code 88890008 which is defined as AUDCLNT_E_UNSUPPORTED_FORMAT. I have looked on the forums, many people have had this problem and they say it may be something wrong with the driver Razer Synapse 2.0 . I analyzed the log files and read it over multiple times, telling me to disable razer synapse on start up, which does not help. I will attach the log file below.
