Mark,
This is not an error. If the audio subsystem (DPCM, not the user)
chooses to activate both I2S and S/PDIF, this means the HDMI audio may
be taken either from I2S or from S/PDIF: both inputs have the right
format and rate.

Mark,
This is not an error. If the audio subsystem (DPCM, not the user)
chooses to activate both I2S and S/PDIF, this means the HDMI audio may
be taken either from I2S or from S/PDIF: both inputs have the right
