Roland UA-55

[Smeefer]

I've been using the Roland UA-25 EX usb external soundcard for 3 years and I'm considering an upgrade to the new Roland UA-55. It does 24bit 192Khz audio. On my present UA-25 EX, I can only record vocals when it's set at 48Khz or lower.

I'm wondering if anyone else is using the UA-55 on a linux system. I use AV Linux 6.0 and I'm hoping that the UA-55 will work out of the box. I want to record and playback audio at at least 24bit 96khz quality (or maybe even try 192khz). Any information is helpful, even if you want to suggest other cards/interfaces. Thank you!

Well, i'm getting one next week, so I'll let you all know how it works on AV Linux 6.0.

Afaik the UA-55 is not USB-2 class compliant and needs a dedicated driver. So it won't work with Linux yet. Or maybe that info is outdated, you can check here when it's up again: http://wiki.linuxaudio.org/wiki/current ... a-55_usb-2

Thanks for trying to let me know AutoStatic. I got it unfortunately. The UA-25 EX had worked great, so i wanted to upgrade to 96khz with full playback AND recording at the same time on linux.

I'm going to let this UA55 wait in my closet. Until then, if there is anything i can do to help developers and programmers make this soundcard work properly in linux debian, please let me know at smeefer at g mail. Thanks.

I'm running AV Linux 6. My usb does recognize that a Roland device is plugged into it.

Code: Select all

~$ lsusb
Bus 002 Device 007: ID 0582:012f Roland Corp. 

It's there! I'm going to restart my computer and see what else happens. If nothing happens, then I might try backing up my files and reinstalling AV Linux 6. I've been having an unsolvable flash plugin problem anyways...

Hi Smeefer, your best bet is to have Clemens Ladisch have a look at it. He's the USB ALSA specialist and might be able to help you out. Best way to reach him is probably to subscribe to https://lists.sourceforge.net/lists/listinfo/alsa-user

Yaay AutoStatic! Thank you for the help. I will keep everyone posted on what happens, here on this thread!

I have some information that I've shared on the alsa-user mailing list as well. The UA-55 does not show up in

Code: Select all

cat /proc/asound/cards

It does show up in lsusb and lsusb -v. I also have some information from my /var/log/messages when I connected the UA-55 through usb.
Here is the /var/log/messages:

I tried to send a few e-mails to the alsa-user list, but I think they were marked as SPAM...

[Pablo]

I saw your e-mail with the [SPAM] tab. I don't know why. Did you subscribe to the list?

[Smeefer]

Yes, I subscribed myself to the list before sending out the first e-mail. I only want to know if there is any progress being made on a potential patch for the UA-55. If there is, I'd like to test it on my computer or provide support in some way.

[Pablo]

I'm sorry I can't help here.

For some reason your e-mails are tagged as [SPAM] and it could be that the people who can help you just ignore them. Maybe, you can contact the list administrator to telll them that your e-mails are not spam

Clemens replied and said he is working on a driver!! Check it out: http://comments.gmane.org/gmane.linux.alsa.devel/102869
I need to figure out how to compile and install my own kernel on AV Linux in order to help him with the driver development. Either that, or i need to get the driver from Clemens and send the driver to someone who can easily compile and install a kernel on AV Linux, then send the kernel to me so i can install and test on my computer with the UA-55. Whew! I'm very ready to get to work ASAP.

[Smeefer]

The patch that will provide support for the Roland UA-55 Quadcapture is being worked on for the linux 3.8 kernel. I've been testing it regularly. Hopefully the next release of AV Linux (6.0.1) will have support for the UA-55 and more new Roland cards as well.

Cool stuff!
