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
hci0: Type: UART
BD Address: 00:06:6E:05:05:05 ACL MTU: 310:10 SCO MTU: 64:8
Unified 21e
Chip version: BlueCore4-ROM
Max key size: 128 bit
SCO mapping: HCI

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!
