so I run amixer -c 1 to see the amixer stuff for my device, and then I look for “x Playback” and I can’t find it.
this is the complete amixer -c 1 >/tmp/amixer.out
fgrep Playback /tmp/amixer.out | fgrep "x "
does not find “x Playback”
amixer.out (234.8 KB)
I am looking for “x Playback” because it is in the /sys/kernel/debug/tracing/trace file.
I don’t see it in the device tree, or the tlv320aic31xx.c file either.
