  Provide hint / tunable for possible asynchronous USB execution. Async
  execution should help us avoiding potential deadlock and illegal locking
  while sleeping in various mixer -> usb calls. To enable it, use
  hint.uaudio.%d.async="1" or sysctl dev.uaudio.%d.async=1. Default is
  disable, to remain compatible with old behaviour (with slight risk of
  potential deadlock).
