Please try the following patch (apply it to the latest git): http://marc.info/?l=linux-bluetooth&m=123054787830678&w=2 You can try the patch "as is", and also with SBC_HIGH_PRECISION define uncommented. High precision mode is naturally more likely to pass the conformance tests. I used my own script for testing with 'tiny_psnr' tool for comparing original file before encoding and the final decoded result (it measures standard deviation and PSNR). It would be interesting to see how our results correlate. According to my tests, encoder should now be OK with this patch. Decoder is definitely in a better shape than the current encoder from git. But the decoder also seems to have bugs which degrade quality significantly in some cases.
