I just installed my 20S. Testing it with my SMH-10, I found a problem with "intercom over music". That is, if I have music playing on the 20S, and I initiate an intercom contact (either 20S to SMH-10 or vice versa), the music doesn't simply fade under as expected. Instead, it chops and cuts in and out abruptly (the "static" in the subject line). That makes the situation worse, because the chops make the music more obvious than just faded under.

Have I got a problem with the settings or...? Is anyone else seeing this?
