[alsa-devel] Trouble about Roland UA-11 UA-33 UA-55 and snd-usb-audio module
Hi guys,
I write you about support of snd-usb-audio module and a relatively-new gamma of devices from Roland/Edirol:
DUO CAPTURE, TRI CAPTURE and QUAD CAPTURE
respectively:
UA-11, UA-33, UA-55
These aren't not listed in the Alsa db. I have searched a solution for a week and I haven't found a trick to make UA-11 to work under Alsa 1.25.0 then I downloaded the driver for try to patch it and I found these devices is not listed in the tricks table
In despair I have played with the switch button called "EXT * **" in the bottom of the unit of UA-11 and magically the device ID is transformed from * 0582:012b to ** 0582:0137
Image: https://dl.dropbox.com/u/32759898/output.jpg (Rear of the UA-11 unit, from the manual)
*Before* (Recognized from udev - Unknown from alsa): http://www.alsa-project.org/db/?f=502ee68cf31882ba9ef23525fd66452c34d329e1
*After* (Recognized from udev - Recognized from alsa): http://www.alsa-project.org/db/?f=b2ae3e4331fb3fe613ba71e7aba1ad2e0e6dcd29
In the tricks table header of ALSA the 0582:0137 stay for PM-1000 in /TODO/ statement. I understand the EXT switch, undiscovered in the manual of the DUO CAPTURE is - as the fact - the Advanced Mode.
Now the peripherical running both in playback and recording in 16 and 24 bit and without any mixer options in alsamixer.
Can you update future releases with this gamma of devices?
Awaiting for your positive response :)
Thanks.
Best regards,
Leonardo

Which is a wiki.

Please show the "lsusb -v" output for these devices in "Advanced" mode.

I know.
I have only the DUO-CAPTURE unit, UA-11.
Unfortunately, I can be useful to you just for that .
So these are the lsusb output in both modes:

You must consider the EXT switch isn't documented in the manual.

Hello, I just got the UA-55 in the mail today. I'm not sure what I need to do in order to begin working on making it work in my AV Linux 6.0 debian squeeze.
I'm a musician, but I don't know any programming languages (yet). I live with a friend who knows java and c++. He said he might be able to assist in a project to get drivers working for these usb 2.0 roland soundcards.
I will do whatever it takes to get the UA-55 operating at 24bit 96khz (or even better 192khz), recording and playback duplex on my operating system (which will be such a nice upgrade from the UA-25 EX). Please let me know how I can help and what I can try on my system to get this device working. Thank you!

Some driver code must be written. I'm working on it (in my copious free time).
Please let me know how I can help and what I can try on my system to get this device working.
Look up how to compile and install your own kernel on your distribution.
Regards, Clemens
One member of the AV Linux development team (trulan) told me that they can add a patch to the next kernel build and I can test it out on my system. If you send me a link where I can download your driver code, then I can link it in this forum: http://www.remastersys.com/forums/index.php?topic=2857.0
I'm excited to get working on this! Thank you.
Smeefer
Clemens,
What kernel version do you prefer me to work with?
Smeefer
Ok. The latest AV Linux kernel version is 3.0.47-avl-10. I will find out if this is close to bleeding edge like i hope it is! Please let me know when you can send me a patch. I will forward it to trulan, the AV Linux kernel developer. If you send it by e-mail or post a link to where I can download it, that would be perfect. Thanks Clemens.

In theory, implicit feedback support was added in kernel 3.5, but there have been lots of important bugfixes since then, so I've just based it on 3.8-rc6:

Hello, what is the status of the support for the UA-55? I get the impression from this discussion that by now it should be in de linux kernel. However, on this list, it is still noted as unsupported:
http://wiki.linuxaudio.org/wiki/hardware_support#roland_-_quad-capture_ua- 55_usb-2
I am planning to buy one, so I would love to know if it works on Linux.

As far as I know, it was supported once at a time, but some later change in the driver broke it for some unknown reason.

Hi all,
I can confirm this. I'm a QUAD CAPTURE user and it was working until the last week. A few updates later and it does not work anymore :-( ... It is listed in lsusb but in alsamixer it says "this sound device does not have any controls". It's incredibly frustrating!
