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
