Re: [Bluez-users] Bluetooth-alsa no sound

[Mike Zhou <netdream1981@gmail.com>]

Dear  Brad:
Thanks for your help. I think the bluetooth-alsa may be work
correctly. But when I use strace aplay --verbose -D hw:1,0 test2.wav,
I got this error at the end:

ioctl(4, 0x400c4150, 0xbffff910)        =3D -1 EIO (Input/output error)
write(2, "aplay: pcm_write:1146: ", 23aplay: pcm_write:1146: ) =3D 23
write(2, "write error: Input/output error", 31write error:
Input/output error) =3D 31
write(2, "\n", 1
)                       =3D 1
exit_group(1)                           =3D ?

Do you think I should reinstall the bluetooth-alsa with CVS version?
Thanks a lot!

Regards!

Mike
