Not really a solution, but I just set a button in lirc to toggle
between the audio states:

begin
  button = a
  prog = irexec
  config = iecset audio 0 ; mythtvosd --bcastaddr=127.0.0.1
--template=alert --alert_text="iecset audio 0"
  config = iecset audio 1 ; mythtvosd --bcastaddr=127.0.0.1
--template=alert --alert_text="iecset audio 1"
end

HTH,
Tim
