I am using iode 6.11 on a Shift6mq. Since switching to iode my phone partners have an echo in the conversation, when I call them via Threema or Signal. For me the sound is normal. This echo does not occur in a cellular call.
Since I did not encounter this behaviour on the same device with the OS I had before (Shift OS 3 L), I assume it has something to do with iode.
Has anyone an idea how I can fix this?
Thanks in advance!
