View Full Version : [all variants] Tascam us 122l Jaunty

I've been looking forward for the jaunty release because of the support for the tascam us 122l USB sound card. Today i decided to give it a go...

"asoundconf list"
--> outputs my onboard card M5455 and the US122L

In my mixer, however, the tascam card does not show up. Tried to make it default via asound-gtk, where it was listed, but that does not change a thing. Several reboots.

Any help/ideas on this?

i've been trying to get my us-144 to work under the jaunty beta as well. i had read that the 2.6.28 kernel had native support and understood that to mean i could just plug it in and it would work. apparently not.

sorry i dont have any answers, but i second your post.

I had believed that my US-122L would have worked straight away too.

I have no idea where to start in trying to make this work. The thing is, the ALSA wiki still doesn't show the US-122L as supported...

My problem is even though the system sees my Tascam us-122l and loads the module alsa does not so pulse does not (I think).
Jack lists it but won't use it. I get [Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server]
Seems to me it should work.
I have given some thought to an .asoundrc file but your supposed to use the result of aplay -l to get the names to use and that returns
no reference to that Tascam.
Stopping and restarting alsa and pulseaudio seem to make no difference as well as having it plugged in on start up or plugging it in later.
I must have missed something, any help would be appreciated. I really need to do some recording.

Hi, thanks to Pax to point me this new thread!

James, I'll answer only to you because you give enough output to find a mistake...

have you read this?
http://wiki.briata.org/doku.php?id=testing_us122l_under_linux#step_3_-_set_alsa

I see that your tascam is recognized as number 1

so check what is inside ~/.asoundrc

than
jackd -RP50 -dalsa -dusb_stream:1 -r44100 -p64 -n2

do not use :0 if your tascam is recognized as number 1!!!!

be also sure that in /etc/modprobe.d/alsa-base

you got
options snd-usb-us122l index=-2

@Earl_Maroon

google is your friend.
there is a wiki, you can start from this
http://wiki.briata.org/doku.php?id=testing_us122l_under_linux

if you need more, there is older thread on ubuntuforums.

Finally with Ubuntu 9.04 there is no need to patch and compile anything!!!!

Actually, with a Tascam US122, nothing has changed, and I must do it the hard way. Was it decided to only support the relatively newer 122L?

I had the same error messages as as Gorean, followed the instructions of federicobriata and the jack server is now working.

What i did, step by step:

$ cat /proc/asound/modules
0 snd_intel8x0
1 snd_usb_us122l

$ cat ~/.asoundrc (missing file in my system)
pcm.!usb_stream {
@args [ CARD ]
@args.CARD {
type string
default "1"
}

type usb_stream

card $CARD
}

$ cat /etc/modprobe.d/alsa-base.conf | grep us122 (mind the .conf suffix!!!)
options snd-usb-us122l index=-2

$ aplay -MDusb_stream:1 -fS24_3LE -r44100 -c2 -twav --period-size=640 ~/test.wav
worked well!

$ jackd -RP50 -dalsa -dusb_stream:1 -r44100 -p64 -n2
worked as well, and this never worked before!

I opend jack controll via the applications/multimedia menu and copied the settings of the last command given.

Thanks a lot federicobriata!

*bump* for some help please!

i have been struggling trying to get this going.. i will post all my alsa info below. One thing i would like to note .. my dmesg just shows device found and set to address 3 etc in ubuntu , but in mandriva , Iget a full description of the device found (both default installs), would this be something in my kernel config? could someone who has a working us-122l send me their .config for me to have a gander? anyhow, here is my config files, maybe someone can look them over..

Also, when booting system , if my tascam is plugged in , my mouse is frozen. so i need to unplug and plug it back in when booted.

thank you!

my first post in this forum. hi everyone.
sorry for that i m not helping much in this post but asking for help as well.

i am using ubuntu karmic 9.10 and try to get the tascam us-144 to work.

i downloaded the us-122l firmware, upgraded alsa with the script i found here (http://ubuntuforums.org/showthread.php?p=6589810) and did


kurt@kurt-laptop:~$ sudo modprobe snd-usb-audio
kurt@kurt-laptop:~$ echo -n 0000:00:1d.7 | sudo tee -a /sys/bus/pci/drivers/ehci_hcd/unbindafter that and a plug-out-plug-in-again, the us-144 was recognized as us-122l, which was my intention:


kurt@kurt-laptop:~$ cat /proc/asound/cards

kurt@kurt-laptop:~$ cat /proc/asound/modules
0 snd_hda_intel
1 snd_usb_us122li created the .asoundrc file like u3000 did and the alsa-base.conf is the same as well, but jackd seems to ignore that:
