Alarm - wake up mode problem

Dear friends,

i have problem with my iphone when is on sleeping mode. When the sleeping mode is turning off and when the wake up alarm is starting my iphone doesn’t make any sound but on the screen the alarm is active. That isue is only when my iphone is paired with my apple watch. My apple watch have normal vibrations as always but no alarm sound on the phone. When i unpair the iphone and the apple watch wake up alarm is functiong normal.

This isue is from 3 days ago, before that everything was functioning without problem.

I tried everything. I rabote the iphone and the apple watch; i reset the settings on my iphone; i reset my apple watch.

And also, i must mention that when i turn on normal alarm the apple watch is vibrating and the phone have the alarm sound (as usual and normal). So the problem is only with the “wake up alarm”.

Thank you for the help.
