Push notification audio not playing when app is in background - OneSignal React Native

Question

I have an application built with react native using onesignal for push notifications. On specific devices (panasonic fz-a3) the push notification is received but no audio is playing when the application is running in the background.

If the application is closed the push is received with audio notification.

I have verified that the android channel is setup properly and the audio is playing on other android devices (samsung) but cant figure out what is missing on these specific panasonic devices (fz-a3)

any help or suggestion is appreciated
