On my L5 running Byzantium I have a short song as notification sound for arriving SMS.
What I observe is that when SMS arrives while the display is off everything sound like expected (playing the song as I know it).
But if the screen is already on and the phone unlocked the song is played with a strong echo effect applied to it.
Can anybody confirm this observation? Any ideas why and how to remove the echo effect?
It’s hard to say for me. It sounds like an echo. If the song would be played twice at nearly the same time it probably could lead to this effect.
I guess chatty wouldn’t emit feedback if the phone is locked? Would that be the explanation why it only happens with the screen unlocked?
I could do a recording of a few seconds if that’d help to judge the situation. Or is there a way to see that two processes are playing a sound if the screen is unlocked?
Maybe it is the man in the middle attack echoing the transmission? (This is humor.)
Yes, I have it too, in my case for the default SMS sound.
