Phone/call function in android apps like whatsapp/telegram [fixed]

Hi All, I didn't found anything about my problem and would ask the sailfish users here. I used Xperia X with Sailfish X before and the voice and video calls with whatsapp android client worked fine. Since I bought my Xperia XA2 and use it with SFOS 3.x, Nobody can hear me or I can hear nobody when I'm using call with Android whatsapp client on XA2. The same problem with ringtone for a whatsapp call, I can't hear that during dualing. I checked already sound android setting. I tried Whatsapp+ Client. I tested the call function with android telegram client, the same problem. So that I'm little bit confused about that and can't find a solution or a workaround for this problem. Maybe somebody has the same issue and can help me? Thank you in advance. Best regards Bratsk
