[Bluez-devel] I can't hstest to replay the audio file recorded by hstest

[cuanyu]

Sorry for repeating this question again. But my last post is in a very
bad style, so I decide to make it clear.
I am using Fedor core 1 and all the USB Bluetooth option are selected as
module. I am using a CSR based USB dongle and here is its information:
I have changed my bluetooth dongle and it is based on CSR chip:
[cuanyu@tom sbin]$ ./hciconfig hci0 version
hci0:   Type: USB
        BD Address: 00:02:72:02:02:E7 ACL MTU: 192:8  SCO MTU: 64:8
        HCI Ver: 1.1 (0x1) HCI Rev: 0x20d LMP Ver: 1.1 (0x1) LMP Subver:
0x20d
        Manufacturer: Cambridge Silicon Radio (10)
[cuanyu@tom sbin]$ ./hciconfig hci0 revision
hci0:   Type: USB
        BD Address: 00:02:72:02:02:E7 ACL MTU: 192:8  SCO MTU: 64:8
        HCI 16.4 (bc02x)
Right now I can use hstest to record the audio from the headset very
well and the file could be replayed by sox like this:
sox -t raw -r 8000 -c 1 -w -s recorded -t ossdsp -w -s /dev/dsp

But I can't replay the recorded file by "hstest play recorded ...". All
I can hear is just very sharp noise. The SCO packets are routed through
HCI instead of the PCM interface because I can see SCO packets in the
hcidump result.

maybe the FC1 kernel is not good enough. Try to install the latest 2.4
with my latest -mh patch.
