I: [pulseaudio] module-udev-detect.c: Found 0 cards.
The debug logs before this line should tell why there weren't any sound
cards found.
module-udev-detect.so found. I don't see if there is problem in log below.
Ok, so according to udev there are no sound devices. What does "ls
-l /dev/snd" print?
root@eukrea-cpuimx25:~# ls -l /dev/snd

Hmm, pulseaudio probably can't use these devices, because they are
accessible only to root and pulseaudio runs under the "pulse" user, so
modifying the access rights is required, but I think the log indicates
that pulseaudio doesn't even try, because according to udev there are no
sound cards.
What does "udevadm info /dev/snd/controlC0" print?
root@eukrea-cpuimx25:~# udevadm info /dev/snd/controlC0
missing option
root@eukrea-cpuimx25:~# udevadm info --query=all --name=/dev/snd/controlC0
P: /devices/platform/soc-audio/sound/card0/controlC0
N: snd/controlC0
E: DEVNAME=/dev/snd/controlC0
E: DEVPATH=/devices/platform/soc-audio/sound/card0/controlC0
E: MAJOR=116

Looks good to me. Can you also paste the output of
udevadm info --query=all /sys/devices/platform/soc-audio/sound/card0
If that also looks good, then I'm out of ideas.
root@eukrea-cpuimx25:~# udevadm info --query=all
--path=/sys/devices/platform/soc-audio/sound/card0
P: /devices/platform/soc-audio/sound/card0
E: DEVPATH=/devices/platform/soc-audio/sound/card0
E: SUBSYSTEM=sound
I don't know it is good...
It has SUBSYSTEM=sound, so PulseAudio should pick it up.
Maybe I could use module-alsa-source or module-alsa-source ? I did some
try without success because of wrong argument.
Yes, that's an option if udev doesn't work. Instead of the sink/source
modules, though, I recommend using module-alsa-card:
load-module module-alsa-card device_id=cpuimxaudio
Yes, I tested that and I have the error :
module-alsa-card.c: Card 'cpuimxaudio' doesn't exist: No such device
and with
load-module module-alsa-card device_id=cpuimxaudio
I have the error :
module-alsa-card.c: Card '/dev/snd/controlC0' doesn't exist: Permission
denied
Also I remenber Adding the user root to the "pulse-access" group (after
creating it) or to the existing "pulse" group does not help "pactl list
cards" to have access.
