[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] hackerpower:
Thanks for the reply.

1. The xml file you mentioned is located in RR in #/etc

There's no system folder inside /etc dir

2. This line "<device name="SND_DEVICE_IN_AUDIO_REC_MIC" acdb_id="41"/>" isn't present in the xml file.

The closest i can find is "<device name="SND_DEVICE_IN_VOICE_REC_QMIC_FLUENCE" acdb_id="8"/>"

Here's my file:

What to do now? :highfive:

PS: With only the value changed to 41 of the camcorder_mic line, the clicking sound bug is still there.
