It looks like the new 'Voice Route' control added by this patch cannot
be switched while sound is playing. This is why qtmoko had issues with
no sound on calls if the phone rings. I see this same behavior in my
modifed SHR. If the inability to switch is part of the hardware, we
will need to stop playing the ringtone, then switch the voicerouting.
