How to test sco over pcm in bluez?

Hi All:
      I have bluez3.28 and kernel2.6.18 with eSCO patch and bluez
2.6.18mh8 patch in hand.I'm using ST's STLC2500 in the bluetooth
module.Since stlc2500c support only sco over pcm , i have its pcm
interface connected to cpu.Right now i've established an eSCO
connection, the problem is i can't find proper means to test audio
data transmit/receive based on sco over pcm.
     I used "aplay -D plug:bluetooth *.wav" and something wrong
happened,please refer to the log.
1.This is how my audio.conf is set:
[General]
Enable=Control
# If we want to disable support for specific services
# Defaults to supporting all implemented services
#Disable=Headset
Disable=
Master=

# SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA)
# Defaults to HCI
SCORouting=PCM

# Headset interface specific options (i.e. options which affect how the audio
# service interacts with remote headset devices)
[Headset]
HFP=true

# Set to true to only support HSP
# Defaults to false
DisableHFP=false

# HFP Gateway features
# Defaults to false
3WayCalling=true
EchoCancelNoiseCancel=true
VoiceRecognition=true
InBandRingtone=true
VoiceTags=true
RejectingCalls=true
EnhancedCallStatus=true
EnhancedCallControl=true
ExtendedErrorResultCodes=true

# Just an example of potential config options for the other interfaces
[A2DP]
SourceCount=2
SBCSources=1
MPEG12Sources=0
SBCSinks=
MPEG12Sinks=

2.Settings in asound.conf:
 pcm.headset {
type bluetooth
}
ctl.headset {
type bluetooth
}
pcm.bluetooth {
type bluetooth
device 00:18:13:E7:B8:D6
profile voice
}

3.The log when tried to play music in bluetooth headset:

Can anybody tell me what's wrong with my log?
Or how to test audio transfer when using the sco over pcm route in hsp/hfp?
