[alsa-devel] ABE routing table without TWL6040

My custom OMAP4 board does not have TWL6040 device. What I do is
1. comment out TWL6040 in arch/arm/mach-omap2/Kconfig
2. comment out twl6040 inside sdp4430_dai[] at sound/soc/omap/sdp4430.c

I find ABE routing table is no longer useful because of changes in steps 1 and 2.

run "arecord -f S16_LE -r 48000 -c 2 -D plughw:0,0 try.wav" returns error:

Recording WAVE 'try.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
try.wav: No such file or directory

dmesg shows dmic_trigger is called.

1. Could anyone please give me hint where I should look into?
2. Try Legacy DMIC to turn off ABE by comment out ABE in 
   sound/soc/omap/kconfig but "No Sound card Found" when boot.
