No sounds on IodéOS 6 beta

The device appears to be entirely muted.
Even in calls, phone does not produce sound.

Mike does work, though.
Vibrating too.

I cannot find a setting that could be wrong.

This is quite a relevant issue.
Iodé team, do you have a solution for me?

Hi, we’re sorry about that. We do not have such an issue in our test devices, and feedback in the beta testing group is good. A new beta should be out soon (maybe today evening, or tomorrow), it could solve your issue. Another possibility is to send us a bug report (in developer options). Or you could reset your device…

Thx Vince!

Your reply (“reset the device”) gave me a silent hint to do the most obvious first: to reboot again.

It solved the problem!
