Nevermind, I confused SBC and MP3.
You're right, however I remember from the IEC specs that the payloader
needs to be different for frequencies below 32kHz, as the MP3 frame size
is divided by two. In other words the code will probably not work even
if the frequencies are supported. I would recommend sticking to
mandatory frequencies for A2DP frequencies (never found a headset that
supported optional frequencies anyway)
