Moin,

Hmm, If I'm not mistaken a2play has even other problems. I tried to play
sbc_test_01.sbc (for a start) through it while doing hcidump -x (the
old hcidump, that is). When doing the set configuration hcidump said

< ACL data: handle 0x002b flags 0x02 dlen 18
    L2CAP(d): cid 0x40 len 14 [psm 25]
      AVDTP(s): Set config cmd: transaction 0
      04 04 01 00 07 06 00 00 81 86 02 FA=20

which decodes as
ACP SEID =3D 1 (OK)
INT SEID =3D 1 (OK)
Media transport capability (OK)
Media Codec capability
	Audio (OK)
	SBC   (OK)
	Sampling frequency =3D 16kHz (should be 48)
	Channel mode =3D Joint stereo (should be mono)
	Block length =3D 4 (should be 16)
	Subbands =3D 8 (should be 4)
	Allocation method =3D SNR (OK)
	Bitspool =3D 2 to 250 (OK)

As you can see the only correct parameter (apart from the hardwired
ones) is the allocation method. All others seem to be kind of bit
reversed. As a side note: The new hcidump AVDTP parser has the same
problem.
