The problem is with the analog inputs, not the audio (I did not test the audio).
The response to the query:
grep "840\|95c\|958\|954\|950" /sys/kernel/debug/pinctrl/44e10800.pinmux/pins
Returns the following:
pin 16 (44e10840.0) 00000008 pinctrl-single
pin 84 (44e10950.0) 00000030 pinctrl-single
pin 85 (44e10954.0) 00000030 pinctrl-single pin
86 (44e10958.0) 00000010 pinctrl-single
pin 87 (44e1095c.0) 00000010 pinctrl-single
Note that the first and last lines differ from your set of responses.
Also, the BeagleBone revision response fto the string
strings /sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom
is:
A335BNLT000C1716BBBG0627
A335BNLT000C1716BBBG0627
A335BNLT000C1716BBBG0627

Does this shed any light on my predicament?
Thank you,
