I obtain other receiver module, bc57f687a05 based (appears as BLK-MD-BC05-B). It provides two profiles, HSP/HFP and A2DP. So now i able to switch profiles, but it is not helpful. Switching between them only changes delay but not removes it. HSP/HFP gives 1/4 s but unacceptable sound quality. A2DP gives 1/2 s regardless of switching. Looks like not driver/OS problem, but unavoidable HW problem. I now wonder if someone (using any OS / HW) can get high quality sound via bluetooth without delays. Unless that, bluetooth considered as unusable at all for audio, and also, Kirk Shrewsbury's answer at link mentioned in #2, considered correct. Thanks.
