Are they turned on in pulse?  Install pavucontrol if it isn't
already installed, and fire it up.  Look at the default device.  Is
it the device you want to have as default, the AMD card, and not
the hdmi device?

So, if you set the AMD card as your default in pavucontrol, your
problem should be solved.
tried, do not resolve the problem, mybe with gnome or other DE
work ...
Hi
thanks for your interest
What if you turn off the amd card in pavucontrol?  (Last tab)

Then run aplay -D plughw:[card number],0 some_wav_file.wav

Pulse no longer controls this device, so it is strictly alsa.  The -D
is telling it which device number to use, use the number from the
aplay -l  command.  It has to be a wav file since aplay doesn't know
about compressed formats unless you add some other options.

Does it play?  If it does, alsa is working, and you only have a pulse
configuration issue.
No
$ aplay -D plughw:0,0 piano2.wav
aplay: main:786: audio open error: Device or resource busy
$ aplay -D plughw:1,0 piano2.wav
aplay: main:786: audio open error: File or directory does not exist

If it doesn't, alsa isn't working, and that would explain why pulse
isn't working, since pulse depends on alsa under the covers.  Are your
speakers plugged in?  Is the volume turned up?  I know, obvious things,
but sometimes those are the things that bite.
yes all is connected and level adjusted to the max value
pavucontrol list this device (sorry i repeat myself )

nothing todo

again thanks

The other thing is that each time that the computer boots, devices
are loaded in random order, unless you put a file
in /etc/modprobe.d.  I use the name soundcard.conf for the file,
and this is what I have in it.  You should be able to modify this
for your needs.
tried, adding
"options snd_hda_intel index=0 model=auto" ... but do not work
It's been a long time since I messed with this, so I've forgotten the
arcane syntax.  You could try the alsa-user mailing list.  Since you
have two hda-intel cards, you need to differentiate between them
somehow, so you are telling alsa that the amd card always goes in slot
0. They might be able to tell you how.  Your command above will accept
either the amd or hdmi for slot 0, since they are both hda-intel.
