headset not detected anymore

I had this happen to me. I tried and tried, and my device would no longer be detected, nomatter what I did.

To solve it, I re-flashed. As it happens, I used SuperZaxxon 155, but I expect re-flashing to the latest is the best thing to do.

Replacement ~/.asoundrc

# ~/.asoundrc
# This is for getting bluetooth working on the OpenPandora.

# Tested and works as of 2013-12-18, SuperZaxxon 155, not updated 
# after installation.

# Make damned sure that you exit any audio-using software before doing 
# any testing.  This includes mixers.

# Example play:
#   mplayer -ao alsa:device=softvol filename.mp3
# (alternately, use the gnome-mplayer which comes with the codec pack)

# FIXME - I have no clue how to get most other players to work!

# TODO - What can I use to do testing, without the user needing a 
#        file?  `speaker-test` isn't available.

# TODO - I used to have a test script to record audio and play it back 
#        immediately.  Something like that would eliminate the need to
#        have a file to play for testing.

# FIXME - mplayer (etc) hang, and must be killed.
#         be absolutely certain to kill all processes.  A hanging 
#         process will completely screw over testing.
#   killall -9 gnome-mplayer mplayer

# FIXME - mplayer (etc) have issues with buffering.

# TODO - I don't know how to get dmixed back in there, to get the 
#        buffering.  It may well be to blame for all kinds of issues.
