The sound is not working

I bought a Hi10X tablet with keyboard and I was updated I have windows 10 and the sound has stopped working. I have read all the messages of the chuwi forums installed drivers and I can hear the sound if I connect some headphones but if I remove them an x appears in the sound sign and I do not hear anything.
