hi all

hstest is not working right, please let me break it down.

My platform: ARM, kernel-2.6.18, bluez-utils/libs-3.30

#hstest play angel44k8b.wav 00:0D:3C:E8:1A:AC 2    
Voice setting: 0x0060
RFCOMM channel connected
SCO audio channel connected (handle 45, mtu 64)
AT+VGS=12

Though the rfcomm and SCO are really connected. their is no sound but noise output from headset. here are some useful information list below.

#hcitool conn
Connections:
        < SCO 00:0D:3C:E8:1A:AC handle 46 state 1 lm SLAVE
        < ACL 00:0D:3C:E8:1A:AC handle 43 state 1 lm MASTER ENCRYPT

#hciconfig hci0 revision

above all, I still can see some SCO packet through hcidump, but i cant here the right sound.

 
what's the problem of this and how to solve it?
Thanks in advance!
