I am using Colibri imx6DL and iris carrier board in my product. I want to use 2 audio-in (may be line-in left & right OR line-in and MIC-IN). There is no provision in amixer or alsamixer to work on both simultaneously. Capture Mux either use mic-in or line-in.
can i use both if yes how can use there is no command for line-in left and right separately.

Hi @deepakrajpoot

Yes, you are right. IMX6 uses the NXP SGTL5000 codec which accepts only one audio stream at one time as described here.
For using line-in and mic at same time, you should add a second codec on your custom carrier board.

Best regards,
Jaski
