Could you give more words about the patch?
Why the patch is needed, and what the patch provides? (e.g. does it
support the all features of the device?)


thanks,

Takashi

What kernel version did you test this patch with?

Re: [PATCH] add Steinberg UR44 USB Audio Interface support to quirks-table

[Cyrus Harmon]

The attached patch provides support for the Steinberg UR44 USB Audio Interface. It’s nothing more than Clemens’ patch to support the UR22 (http://linuxaudio.org/mailarchive/lad/2013/2/23/197831), with the device ID modified for the UR44. The patch was tested with kernel versions 3.12.11 and 3.12.12 and I have primarily used it with a PREEMPT RT-patched 3.12.12-rt kernel. I would imagine there are additional features of this audio interface that aren’t supported by the patch, but basic recording and playback seems to work.

I should note that on one of the systems that I used to test the patch I was never able to achieve xrun-free JACK performance at -p256 -n3 as I would invariably see xruns roughly once every minute. But this is a new box (Intel haswell NUC) and it seems there are many possible sources of the unacceptable latency. The good news is that an older i3 box, the performance was much better. Still, at some point it would be nice to understand if the problem lies in 1) the device, 2) the ALSA drivers, 3) the USB drivers, 4) IRQ handling, 5) CPU-specific features (power saving modes, SMIs, etc…) or 6) somewhere else. In the meantime, the patch at least makes the kernel recognize and talk to the UR44.

Thanks in advance for any comments/suggestions on the patch.

Could you resubmit the patch with these comments (concisely) in
changelog?

In theory, kernel 3.11 and later should support this device without
a quirk entry.  I guess it actually does not?

This sounds as if the playback stream needs to be synchronized to the
recording stream.

What is the output of "lsusb -v" for this device?

I had to rebuild an unpatched kernel on this box to convince myself that the stock 3.12.12 (ft-patched) kernel doesn’t recognize this device and, fortunately for my sanity at least, no, the stock kernel doesn’t support this device.

Interesting. I’m not quite sure what that means and why the performance would be different between the two boxes, but if there’s a way to get the latency down, I would be thrilled.

Strange; in theory, the driver should be able to pick up these
descriptors.

Are there any error messages in the system log when you plug it in or
reload the unpatch snd-usb-audio driver?

Here’s what I get with the unpatched kernel:

Following up on this from last week, here’s the error message I see with an unpatched kernel:

Any suggestions for further debugging this?

Any pointers on where I might look to figure out how to do this?

thanks again,

Re: [PATCH] add Steinberg UR44 USB Audio Interface support to quirks-table

[Cyrus Harmon]

Well, it's 7 months on and I'm still using a patched kernel to access my 
UR44. Any chance of either seeing my original patch committed, or some 
suggestions on a more proper fix, if there's something with my original 
patch?

thanks,

Cyrus

Re: [PATCH] add Steinberg UR44 USB Audio Interface support to quirks-table

[Cyrus Harmon]

I have used a number of 3.1x kernels. At the moment, I'm writing this 
from a 3.17.0 kernel that doesn't recognize the UR44 without my patch.

thanks,

Cyrus

OK, could you repost the patch (and put me to Cc) so that I can apply
to for-next branch?

Re: [PATCH] add Steinberg UR44 USB Audio Interface support to quirks-table

[Cyrus Harmon]

Hi Takashi,

Clemens has sent me another diagnostic/debugging patch to try. Perhaps 
we should wait to see the results of that before pushing to for-next. If 
we don't get a deeper understanding of the problem in the next couple of 
days, I'll send along the original patch.

thanks,

Cyrus

I'm not sure the debugging patch here was properly applied/installed, 
but I think so. In any event, perhaps with this patch, and definitely 
for your previous 2 patches, updated for the 3.19-rc7 sources, I get the 
following errors when I try to load snd-usb-aduio:

So the call that must be failing is:

     err = snd_card_register(chip->card);

and of course this all works with the quirks table modified for the 
ur44. I'm at a loss. Any further debugging suggestions would be greatly 
appreciated.

thanks,

Cyrus

Re: [PATCH] add Steinberg UR44 USB Audio Interface support to quirks-table

[Cyrus Harmon]

On a somewhat related note, is there a way to apply changes to things 
in, say, sound/usb and compile/install those changes without a few 
kernel rebuild/install? Or, even better, without a reboot? Would 
certainly shorting the debug cycle time for me. In this case I'm 
interested in finding out what quirk->type is when it gets to 
snd_usb_create_quirk as it looks like the function in the quirk_funcs 
table that gets called here produces the first suspect error. Adding a 
dev_info, followed by a kernel rebuild, reinstall, reboot (and the fact 
that my broken nvidia drivers require reinstalling the video driver 
every time I install a new kernel) makes for a tedious process!

thanks!

It's a standard procedure, something like...

	% mkdir /somewhere
	% cd /somewhere
	% cp -a /there/linux/sound .
	% patch -p1 < your-usb.patch
	% make -C /lib/modules/`uname -r`/build M=$PWD/sound/usb
	% su
	# make -C /lib/modules/`uname -r`/build M=$PWD/sound/usb modules_install
	# modprobe -r snd-usb-audio
	# modprobe snd-usb-audio

That's what I was looking for!

Thanks!

Cyrus,

There's an automated patcher for the UR22 on Ubuntu @ Steinberg forums -
maybe you can adapt it for your purposes.

Re: [PATCH] add Steinberg UR44 USB Audio Interface support to quirks-table

[Cyrus Harmon]

Dear Takashi,

Sorry for the delay in getting back to this. Your instructions seem 
close, but I've run into the following issues:

1. the module is installed in  /lib/modules/`uname -r`/extra instead of 
kernel/sound/usb

2. I can get around that with:

sudo insmod /lib/modules/`uname -r`/extra/snd-usbmidi-lib.ko
sudo insmod /lib/modules/`uname -r`/extra/snd-usb-audio.ko

but there's probably a better way.

3. I can't do the same tricks with snd-pcm as I get the following error:

sly@madbox:/lib/modules/3.19.0-rc7-local$ sudo modprobe -r snd-pcm
modprobe: FATAL: Module snd_pcm is in use.

Is there a way to disable snd_pcm and reload the module? Barring that, I 
at least want to be able to install the new snd_pcm and reboot, without 
having to rebuild the whole kernel, so solving problem 1 would 
presumably help for that.

Thanks for your help!

Cyrus

modprobe will load from extra directory before others automatically.

Unload the module referring to snd-pcm, in your case, snd-usb-audio at
first.

>>> [    2.964094] snd-usb-audio 3-3.2:1.0: checking PCM interface
>>> [    2.964104] snd-usb-audio: probe of 3-3.2:1.0 failed with error -5

The first error is harmless (the control interface is not a PCM
interface).

>>> ...
>>> [    2.970930] snd-usb-audio: probe of 3-3.2:1.1 failed with error -5

The second error happens during snd_card_register().  In other words,
there's probably something about the PCM device that makes
snd_pcm_dev_register() unhappy.

[PATCH] add Steinberg UR44 USB Audio Interface support to quirks-table.

[Cyrus Harmon]

 * The patch is based on Clemens Ladisch's patch to support the UR22
   (http://linuxaudio.org/mailarchive/lad/2013/2/23/197831), with the
   device ID modified for the UR44. The patch was tested with kernel
   versions 3.12.11 and 3.12.12 and a PREEMPT RT-patched 3.12.12-rt
   kernel. Basic recording and playback appear to work.

 * NB: On one of the systems that I used to test the patch, I was
   never able to achieve xrun-free JACK performance at -p256 -n3 as I
   would invariably see xruns roughly once every minute. But this is a
   new box (Intel haswell NUC) and it seems there are many possible
   sources of the unacceptable latency. On an older i3 box, the
   performance was much better.
