Hi All:
Im using ALSA 1.0.14 and bluez 3.20 and linux 2.6.18.The linux 2.6.18
(montavista) is running on an embeded development board(using S3C2410).
When i tried to use 'aplay' to connect my bluetooth headset, i got
the following error from ALSA:
$ aplay -D bluetooth /1.wav

hcid[318]: Audio service (audio) was killed by signal 7
ALSA's aplay reports an "Input/output error".
Later i digged into alsa-lib-1.0.14/src/pcm/pcm.c and found that
snd_config_search_definition() returns an error.
It seems ALSA didn't find the proper conf definition or something like
that.
My ".asoundrc" is as followed:
pcm.a2dpd {
type a2dpd
}
pcm.bluetooth {
type bluetooth
device 00:0D:3C:EB:53:F0
}
pcm.!default {
type hw
card 0
device 0
}
pcm.card0 {
type hw
card 0
}
ctl.card0 {
type hw
card 0
}
Does someone have any idea about what's going wrong in this?
Thanks in advance!
