aplay or mplayer are talking to the ALSA device that uses the A2DP profile.
The phone app needs to use the device with the HFP profile. It looks like
you got that set up in .asoundrc since a plausible subroutine is reporting
the error. Next question: does your headset do HFP, or is it purely a
music headset (A2DP)? Some headsets, including the Motorola HT820, will
auto-switch, but I think not every music headset will do so. Hope this
helps!
