Attempting to get a Zoom R16 working

The Zoom R16 is an 8 track mixer, recorder or audio interface that works with Windows or OS X. Until recently it's been impossible to get it working on Linux, however a few enterprising people have managed to make an entry to sound/usb/quirk-table.h in order to get some functionality working (8 audio inputs, midi control surface).

So yesterday I set about patching my own kernel, unfortunately it didn't go well, I got the following error using this patch:

In file included from sound/usb/card.c:732:0:
sound/usb/quirks-table.h:3127:7: error: ‘altset_idx’ undeclared here (not in a function)
       altset_idx = 1,
       ^
scripts/Makefile.build:308: recipe for target 'sound/usb/card.o' failed
make[2]: *** [sound/usb/card.o] Error 1
scripts/Makefile.build:455: recipe for target 'sound/usb' failed
make[1]: *** [sound/usb] Error 2
Makefile:816: recipe for target 'sound' failed
make: *** [sound] Error 2
make: *** Waiting for unfinished jobs....

I'm not at all qualified to debug this, I've never written anything in C, let alone tried to add something to the kernel before. Would anyone be able to tell me were the patch went wrong?

I'm also available on IRC in #archlinux, just ping "meow", whatever is easiest.

Re: Attempting to get a Zoom R16 working

I think it's a syntax error, there is a missing . infront of altset_idx = 1, on line 41.

Try this patch: https://gist.github.com/vostok4/10363990 (or just look at the revision).

That got it compiling, I installed it, setup nvidia-hook/dkms from AUR, and configured grub. On boot I got a huge stack trace.

I don't think I'm going to be able to get this working :S

I also own this device, it would be great if we make it work!

Re: Attempting to get a Zoom R16 working

I was able to boot 3.13.9 with the patch, however putting it into audio interface mode caused the system to lockup. I'll be trying again this evening with kernel 3.14, I'll share my package source when I do so you can try it too.

Re: Attempting to get a Zoom R16 working

Some progress at least, using this patch I was able to get the device to show up:

↪ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: AD1984A Analog [AD1984A Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

  Subdevice #0: subdevice #0
card 1: R16 [R16], device 0: USB Audio [USB Audio]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

However most of the time it would hang the computer when I enabled the audio interface, until I disabled the audio interface mode. This includes when I attempted to configure Jack to use it:

I don't really know what's going on, and I don't have the necessary knowledge required to debug it. Any input is welcome.

Reading the mailing lists, they say that capture works and they try to make playback to work
