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 !!
