Compiling new kernel for Tascam US-122l

[Earl_Maroon]

I recently bought the Tascam US-122l (USB sound card, not yet supported in ALSA), thinking that it was the same as the US-122 (which is supported by ALSA). I have found a walkthrough that has been claimed to work for this and it involves compiling and installing a patched kernel. The thing is, the walkthrough is for Debian, and while I know that Ubuntu is based on Debian I'm not sure quite how compatible the walkthrough is. I assume it would be pretty fatal for my current install if I broke the kernel. There is one particular line which mentions *amd64.deb, but I use an x86. If someone could take a look at this and let me know if this is safe and if there is anything that needs to be changed for my purposes I'd be very grateful.

The walkthrough is at:

i also bought a us-144(us-122l) and have been following this tutorial

http://wiki.briata.org/doku.php?id=t...2l_under_linux

which does involve compiling a new kernel, since its a new kernel im fine with it, but after its compiled i will have to patch it for RealTime

my issue is there are errors in my quest

after compiling the kernel i get errors

 MODPOST 1911 modules
ERROR: "snd_hwdep_new" [sound/usb/usx2y/snd-usb-us122l.ko] undefined!
WARNING: modpost: Found 15 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
make[2]: *** [__modpost] Error 1
make[1]: *** [modules] Error 2
make[1]: Leaving directory `/usr/src/linux-2.6.25.4'
make: *** [debian/stamp-build-kernel] Error 2

and then the next command after that are

 dpkg -i ../linux-image-2.6.25.4-us122l_1_amd64.deb
 dpkg -i ../*-modules-2.6.25-us122l_*1_amd64.deb

naturally there are no amd64.deb's but i did find the linux-image of the kernel, but the modules*.deb is not there, was it not built due to the module error from the kernel compiling?

when i continue on i get errors here with this command

CFLAGS="-Wall -g -O2" ./configure --prefix=/usr \
	    --mandir=\$${prefix}/share/man \
	    --infodir=\$${prefix}/share/info \
	    --host=$(shell dpkg-architecture -qDEB_HOST_GNU_TYPE) \
	    --build=$(shell dpkg-architecture -qDEB_BUILD_GNU_TYPE) \
	    --enable-static

i am told 3 times about bash commands being bad, unfortunately i cant copy and paste it here but its generic bash command errors

the next step was packaging and i get this error

chmod: changing permissions of `/usr/lib/alsa-lib/libasound_module_pcm_jack.a': No such file or directory
make[2]: *** [install-asound_module_pcm_jackLTLIBRARIES] Error 1

make: *** [install-recursive] Error 1

Ciao!

Lets leave for the moment RealTime patch...
You must follow the guide step by step. You can't skip some part.
The modules* will be only when 'make-kpkg kernel_image modules_image' will not give error.

As superusers type:
# cd /usr/src/linux
than paste all output of:
# cat .config | grep SND
If you don't get:
CONFIG_SND_HWDEP=m
that's maybe the problem, you can add it when you are in 'menuconfig'

Anyway some more detail will be useful to help you...
Which kernel are you using? which ubuntu version?
I'm installing now ubuntu 8.04 hardy heron, I'll try to add us122l support as soon as I can..

i have redone my system and dont show any sign of the patch as yet. i will wait for you to complete then i will try again.

[federicobriata]

Hello,
I add preliminary howto for Ubuntu 8.04 Hardy Heron.

For Ubuntu intrepid should be the same step except for libasound2-plugins sections, where with 'apt-get source alsa-plugins' you'll get alsa-utils 1.0.16 instead of 1.0.15.

Please let me know if is working.

Best regards,

Federico

[keithacole]

im trying your new method out now. so far no errors, except for having a hard time grabbing the patch, (kept timing out on the download)

but kernel is compiling now.

i read in about he issues between usb 1 and 2, should the device be on usb 1 instead of 2? with this patch?

[keithacole]

OK, everything got compiled and i ran into no errors, except that the device is still not listed in /proc/asound/cards

i see the module snd-usb-us122l i modprobe it and pull the cable on the interface, i check dmesg and there are no errors, but still the device doesnt list under /proc/asound/cards

is it because of alsa 1.0.15 ?

[federicobriata]

Hi!
after kernel patches you should get it with cat /proc/asound/cards.

First test I didn't get working too in usb2,
I check kernel messages (sudo dmesg) and something wasn't good with ehci patch, I removed ehci_hcd (sudo rmmod ehci_hcd) plug it again and was working but in usb1 mode.
Than I've seen that us122l-patches.tar.bz2 witch I download from gmane.org was an empty file, so I rebuild kernel with ehc patch and now is ok.
Maybe have you got the same inconvenience?

I also realize that I miss few step for Alsa-plugins STEP for Ubuntu, now usb_stream is included correctly in libasound2-plugins.

Regards,
Federico

[keithacole]

sudo rmmod ehci_hcd) did not work for me. i still dont have the device show up in /proc/asound/cards. but it does show up in lsusb.

could you create a .deb package from your system that would work?
