The speaker may not have a HSET (headset) service, but 
an A2DP (advanced audio distribution profile) instead.

The bta2dpd program supports the latter, you need to
use it together with a 'pad' device to get an audio(4)
style interface that e.g. music players can use.

HSET is limited to low quality audio.
