sound modules?

[jd1]

hi,
i would like to use a usb soundcard (snd-usb-audio), but there are no kernel modules.
i'm using kernel 2.6.31.6_SMP_820.
in /lib/modules/2.6.39-ARCH/... there are drivers.

is there a way to get these drivers or to switch the kernel?

By the kernel in use, the problem is with the kernel itself.

This is being worked on.

I have the same kernel and am trying to compile the snd-usb-audio driver. I am running into this error message:
$this->bbcode_second_pass_code('', 'Makefile:547: /usr/src/linux/arch//Makefile: No such file or directory')

Is this a related issue? If not, is this Makefile a file that is generated or should it be included in the source code? Any pointers?

You'd need the sources for the OXNAS kernel, again, they dont line up to the mainline... I am working on it.

Hi Warhead,

Thanx for the work you put into this. (I would if I could.) Next few questions will show my ignorance, but that is the only way to learn..

1. I am guessing I need new Linux source code in order to compile yes?
2. Is that what you are working on?
3. If so, when the code is available, how will you announce this? I want to be first in line to try it out.

Also, if you need someone to help you trouble shoot or test it, I can help out.

Essentially I just need to package them up all pretty, and tell people how to use them.

The trick here is that people then need to build from that, with my modified /arch/arm/mm/cache-v6.S, etc, etc.

After that, they'd need to test via a tftpboot from uboot, and eventually properly & safely save it to NAND, only after it is tested...

I really wish it wasn't so complicated to manage.

Hi WarheadsSE,

How's it coming? Any idea when the code will be ready?

Let me know how I can be of assistance.

any update on this?

i am trying to get my usb-dac to work with a -B04 but hitting the brick wall. Is it still necessary to add snd-usb-audio to the kernel (because thats where i fail)

[WarheadsSE]

Yes, however I am having the joys of trying to test new kernel & modules. I have no USB DAC to test with, but I have tested iptables/netfilter .. crashed with null pointer deref after ~ 10 hours.

]does the updated kernel support snd-usb-audio?

i tried to load the package with modprobe, which seems to work (doesnt give an error). but I fail at setting up alsa:

$this->bbcode_second_pass_code('', '[root@alarm2 /]# alsactl init

$this->bbcode_second_pass_code('', '[root@alarm2 /]# alsamixer

and

$this->bbcode_second_pass_code('', '[root@alarm2 /]# speaker-test

speaker-test 1.0.25

I know that this is not the ALSA Forum but if this is kernel related you'd probably know and I can stop wasting my time with trying to get this to work
