Re: meson S905 GX arecord: main:828: audio open error: Invalid argument

I have solved some issues, audio-routing was missing on device tree, son cpu and codec playback and capture stremas where not properly connected, but arecord does not work yet.
there is no default nor sysdefault card when I run arecord -L:
root@hardkernel-odroidc2:~# arecord -L
null
Discard all samples (playback) or generate zero samples (capture)
usbstream:CARD=S905
GXBB ODROID-C2 S905
USB Stream Output

it should look like aplay -L:
root@hardkernel-odroidc2:~# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
default:CARD=S905
GXBB ODROID-C2 S905,
Default Audio Device
sysdefault:CARD=S905
GXBB ODROID-C2 S905,
Default Audio Device
usbstream:CARD=S905
GXBB ODROID-C2 S905
USB Stream Output

Any ideas?
This is the strace of arecord command, it gets stuck on

I have modified play driver and developed capture driver for meson S905 GX device (Odroid-C2)  based on mainline Linux v5.6.
I have also modified CS4245 codec driver.
"play" works fine:

Playing WAVE '/usr/share/sounds/alsa/Front_Right.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

but "arecord" gives me an error message:

root@hardkernel-odroidc2:~# arecord -D plughw:0,3 -c 1 -f dat /dev/null

Could you help me trying to debug this issue?
Thanks and regards
