Distortion in voice transmitted via SDR Console to Adalm Pluto

Good morning everyone.
After upgrading to SDR Console v. 3.4 from 3.3 long time ago ( now I use the latest one ) I found immediatly a couple of anomalies of which the most "annoying" is the distortion of the audio transmitted via Adalm Pluto. I use SDR Console to access to QO-100 satellite via Adalm Pluto "system". In some situations, it is not immediately apparent that the problem exists, for example when the transmission frequency cannot be in line with the reception frequency (Split-mode).
Let me explain: after some unspecified and always variable time, listening again to my voice transmitted to earth by the ES'Hail2-QO-100 satellite it is extremely distorted.
It is sufficient to stop the software and restart it to restore the correct broadcast.
Does this happen to anyone else?
If so, how did you solve it? Any idea would be appreciate.
Thanks for your attention.
Paolo

As a non-user of QO-100 one thing comes immediately to mind. Use a lower sample rate. And otherwise reduce the demands on the USB link and your machine's computational resources.

Even more generically, describe your setup including your computer and its resources. Then attach to that description an unedited screen shot showing as much detail of settings etc as possible. Then somebody who has more experience with this will be able to help you better.
