[Bluez-users] SuSE and Audio

[Jérôme Stadelmann]

Hello everybody

I'm actually a nb with linux, but I have to develop an application with =
some
audio bluetooth transmission. Actually I have a SuSE 9.0 distribution.
Marcel (Holtmann) said that I have to patch my kernel, but his patch =
doesn't
work with the SuSE kernel source. And I don't know how to do it easily
without having to configure all my computer.

Please, can somebody help me or give me a hint?
Thanks

Jerome

SuSE uses its on kernel and I can't tell you if the needed patches are
included or not. You must install a vanilla kernel.

Download latest vanilla kernel from www.kernel.org and patch it with Marcel=
s=20
mh patch and recompile it.
Vendor's kernels are not supported.

Hi Marcel

I just install the new 2.6.21 kernel and updated it with your patch (mh3 =
I
think) but the problem is the same.
I can establish a contact with hsplay or hstest and I can hear some =
noise in
the headset, but nothing like the mp3 file I am sending to it.

Regards,

Jerome

what kernel are you talking about 2.4.21 or 2.6.1? For the 2.4.21 you
need at least -mh4.

What does "hciconfig hci0 revision" say? You need a SCO over HCI mapping
and I never tested this stuff on a 2.6 kernel.

Marcel

Sorry :) It's the 2.6.1-mh3

> What does "hciconfig hci0 revision" say? You need a SCO over HCI =

It gives me SCO mapping : HCI

PS. I've just seen that I have some problems with mpg123 (can't open
/dev/dsp) and maybe that's the reason.

you have to enable CONFIG_BT_HCIUSB_SCO, but this can cause crashes at
unplug on UHCI host adapters.

This is correct, but I never checked that it also works with 2.6.

It's already done...

So you think it's better for me to use an older kernel ?

I don't know, because I haven't yet played with SCO and 2.6.
