Hi  Dhanush

one can check registered audio devices using sect.7.1.2.4 Sound Card Information and some

alsa methods described in sect.7.4.3 attached Linux Manual.

Please try with Linux Binary Demo Files - i.MX 6UltraLite, i.MX 6ULL, i.MX 7Dual

May be useful some audio unit tests:

mxc_amix_test\test - imx-test - i.MX Driver Test Application Software 

Best regards
igor
