Hmm..., I'm confusing
Does it mean you want to use "playback only" on it ?
If so, did you get below warning too ?
	 "both playback/capture are available, but not using playback_only flag (%s)\n",

If not, can you please fill below ?

Card
	dpcm_playback = (0 or 1)
	dpcm_capture  = (0 or 1)
	playback_only = (0 or 1)
	capture_only  = (0 or 1)
BE.CPU
	playback = (available, not available)
	capture  = (available, not available)
BE.Codec
	playback = (available, not available)
	capture  = (available, not available)
Expect
	playback = (available, not available)
	capture  = (available, not available)

Thank you for your help !!

Best regards
