How do I bring stereo PCM WAV 32,000Hz with a stream of 1024 kbps (125 KB) to the headset with Bluetooth 2.1 on a CM7 smartphone with DSPManager? Is this possible? SBC is really a bad idea.

Maybe it's possible with the Headset Profile (HSP)? I don`t know about supported codecs in this profile.

@TJD: Because it compresses the compressed stream. My Epic 4G don`t have Apt-X support. My headset Gemix BH-04A yellow.

    A2DP can't be used to send uncompressed PCM. The profile allows for a variety of codecs, but SBC is the only required codec, and both ends of the connection must agree on a commonly supported choice. Vast majority of connections will just use SBC, but some devices support MP3, AAC, or AptX – TJD Sep 14 '12 at 15:00
  • I get it. Thanks for the reply. Headset Profile can only support mono channel, but in PCM. Still, how to get a headset to take raw audio. Is it impossible? – weter Sep 14 '12 at 20:52
