I am having another strange problem, sometime when I record from a SCO
channel in 16bit (0x0060) to a file the first byte is missing and when I
play it back I listen just caos.
But if I cut the first byte, or I add a byte in front of the file, then I
can listen it fine.
Is there a way to be sure that I am reading the packet in the right way?

check the mailing list archive, because I remember that there was a
thread about this problem.

Ciao Suriyan,
I was looking, few months ago, for a way to solve a problem more or less
like your.
All what I could do was to set the headphones to HV3 and the bt-dongle too,
in this mode it was possible to "listen" audio on 3 different channels, the
problem, for me, was that this channels were "mixed" so if with a channel I
was receiving 24bit with 3 channels they were 72, but I could not find a way
to "demux" this caos who was coming out, but I remember I found a way to
"create" 3 different sco connections with just one bt-(usb)-dongle.

this sounds like a problem with the wrong alternate setting on the ISOC
interface of the USB device. Your workaround is not reliable and maybe
it is CSR specific. To get more than one SCO channel working the hci_usb
driver must be fixed to dynamicaly change the alternate settting.
Regards
Marcel

I try to use the computer as a bluetooth headphone for the S55, it works
great with nokia and motorola, but not yet with the siemens, I think, maybe,
I need to send some "special" AT command (at+ckpd=200 return error) or maybe
I need to configure something with spdtool to let the S55 know that it is
working with a bt-headphone, any idea about?

hi
we have wacky problems with bluetooth-alsa when you connect to the
handsfree rather than the headset profile. does sdptool show you are
connecting to the channel for the phone's headset profile?
