Run

  aplay - l

Is the wanted card hw: 1?

If so, move both files to /root

  sudo mv -i  /etc/modprobe.d/alsa-base.con* /root

and generate a new file, with no other content, but 'options snd slots=snd_hda_intel'
  echo "options snd slots=snd_hda_intel" |  sudo tee /etc/modprobe.d/alsa-base.conf
reboot and run
   aplay -l
the sound device now must be hw:0. If no sound server runs, neither pulseaudio, nor jack and you didn't setup ALSA to some custom setting, then it should be available for all apps using plain ALSA and that usually try to connect with the default device. If an app grabbed the device, no other app could access it at the same time. To make it available for another app, you first need to close the app using the sound device, before you open the other app.
If more than one app should use the device at the same time, you need to use a sound server or dmix.
Regards,
Ralf
