[Bluez-users] error when loading snd-bt-sco

[Bluez-users] error when loading snd-bt-sco

[Jerry Geis]

I have downloaded 2.6.16.4, compiled and installed it, rebooted. ( I am 
using centos 4.3)

I downloaded alsa-project.org 1.0.11rc5, compiled and installed it. 
Sound works on my machine.
I downloaded bluetooth-alsa.sourceforge.net and compiled and installed 
snd-bt-sco kernel module.
When I modprobe snd-bt-sco it says:

Error inserting snd_bt_sco  (/lib/modules/2.6.16.4/extra/snd-bt-sco.ko) 
Unknown symbol in module. see dmesg

the output from dmesg gives:

What have I not down correctly... Thanks,

there's a trick to get the snd_hwdep_new module built automatically but
I haven't gotten it worked into cvs. in the meantime, build the emu10k1
driver so you get it through that route.

Brad,

I went into the alsa-driver directory did a "./configure 
--with-cards=all" so as to include
the emu10k1. did the make and make install, redid alsa-libs, redid 
alsa-utils, rebooted.
recomiled btsco and btsco/kernel.

then when I tried to "modprobe snd-bt-sco" I get the same issue... many
warnings about unknown symbols.

Am I not doing what your suggesting? If not can you give me more details on
what you want me to try?

THanks

Jerry

Are you using the standalone alsa download? We've only gotten it to work
with the integrated alsa in recent kernels.

Brad,

I did download the alsa-drivers, libs and tools 1.0.11rc5.
Are you saying that this does not work at this time?

Should I just recompile my kernel again to wipe out the alsa compile?
Thanks,

Jerry

you need to use the drivers that come with the kernel. not sure if the
standalone drivers will get zapped properly; you should wipe them
manually to be sure.
