Hi All...
Iam a novice in linux and bluetooth....
I have a very specific question regarding the headset and audio profile....
Why is it that ALSA and Bluetooth can connect to a headset???
I mean what ALSA can do which others can't do?

Can't it be on a lil lower kernel of 2.4.20 or something... or with
downloaded ALSA libraries ... why only with an "integrated"  kernel with
ALSA???? ( i,e a newer kernel.... )


Please help me find answers to these...

I need to set up an audio gateway in a lower kernel version i.e 2.4.20....



with lots of hopes
Soumya

Get the bluez cvs project and have a look at utils/test/scotest.c

You can write your app to do all the audio transfers itself and you
won't have to patch or upgrade the kernel.

Of course you're mostly on your own :) so good luck.

Hi Brad...
I have been going through the archives of this mailing list regarding the
SCO audio support by Marcel and Max in 2002 discussing the demerits in the
hci_usb driver to support SCO... (
http://sourceforge.net/mailarchive/message.php?msg_id=2651899)
Is the problem discussed rectified??
My question is
1) Does the hci_usb.o module support SCO???
2) Iam planning to set up 2 USB dongles (CSR) for headset and Audio gateway
each...
Can I use scotest to send voice?? will I face problems??

Iam yet to write the code

Soumya
