Problem with bluetooth sound... working but not working

Hi everyone,

I'm new to this list, ny name is Preben and from Denmark...

Hardware:
Logitech F-0228A headset
Trust BT-1300TP bluetooth usb adapter

lsusb (the mouse is a logitech, so the chip must be broadcom):
-----------------
Bus 001 Device 003: ID 046d:c50a Logitech, Inc.
Bus 001 Device 002: ID 0a5c:200a Broadcom Corp.
Bus 001 Device 001: ID 0000:0000
-----------------

The problem is, that all seems to work fine, but no sound will play.

This is the output from btsco when in verbose mode.
--------------
preben@laptop run $ ./connect_headset
btsco v0.4c
Device is 1:0
Voice setting: 0x0060

Only "noise" is present in the speaker when trying to play with
aplay -B 1000000 -D plughw:Headset ../call_in.wav

and it doesn't stop either.

Output from hciconfig hci0 revision
-------------
laptop preben # hciconfig hci0 revision
hci0: Type: USB

       BD Address: 00:0E:A1:33:94:FE ACL MTU: 377:10 SCO MTU: 16:0
       Firmware 263.3 / 9

Similar configurations (headset+dongle) works on windows-computers, but why isn't there a SCO: HCI/PCM in the hciconfig hci0 revision output.

I'm using gentoo and in portage there are firmware for broadcom devices. Should this somehow be stuffed into the device or???

This is the scripts I use for init:
------------
/etc/init.d/bluetooth start
hciconfig hci0 voice 0x0060
modprobe snd-bt-sco
------------

and
------------
btsco -v 00:0D:44:2F:4B:25
------------

I would really like this to work...

Thanks
Preben

Because this chip is not supported for SCO under linux.

Get a CSR based chip. Did that here, too.

Hi everyone,

Will there be any support for SCO in the near future of broadcom devices?
I won't go buy a cellink, if the support is on it's way!

Btw. my broadcom device works with the standard drivers hci_usb!

An lsusb gives this:
ID Broadcom 0a5c:200a Broadcom Corp.

Thanks for your help!

Preben,

Sorry... no one is working on broadcom sco and no one has detailed docs anyway as far as I know.
