For the FM version of HD, broadcasters have 96Kb/s to play with. Most broadcasters are doing what is called in the trade as "multicasting". In other words they are taking the 96Kb/s stream and running two or more stereo channels on it. Many broadcast groups are doing 48Kb/s each. A number of NPR stations are running 64Kb/s as a simulcast of the analog carrier and using 32Kb/s for an alternitive feed. Needless to say, 44Kb/s stereo sounds pretty bad.
