New Revision: 338038
URL: https://svnweb.freebsd.org/changeset/base/338038

Log:
  Extending the delay cycles to give the codec more time to pump ADC data across the AC-link.
  
  Without this patch, some CS4614 cards will need users to reload the driver manually or
  the hardware won't be initialised properly. Something like:
  
  	# kldload snd_csa
  	# kldunload snd_csa
  	# kldload snd_csa
  
  Tested with:	Terratec SiXPack 5.1+
