Line 6 POD HD Pro X with Linux

CeeJayTheFirst · July 25, 2015

Greetings everyone.

I'm here to clear a few things out about using the Line 6 POD HD Pro X with Linux OS, more precisely, Ubuntu 14.04 LTS.

The main question is: Is it possible?

I am curious about the possibility of using this amp's digital interface for recording and also I'd like to know if it is possible to use the POD's editor, all done in my OS of choice.

I am aware that Line 6 doesn't provide any drivers for Linux machines but in my research I've stumbled upon a thread about a project developing linux drivers not the HD Pro X but the HD500, and I wonder if those can be used with the HD Pro X.

Thank you for any replies.

at least in kernel 4.4 are included line6 modules. In ubuntu if you go to /lib/modules/4.4.0-36-generic/kernel/sound/usb/line6 you will see the modules:

snd-usb-line6
snd-usb-podhd
snd-usb-pod
snd-usb-toneport
snd-usb-variax

you should be able to load them with: modprobe
example:
sudo modprobe snd-usb-podhd

unfortunnately I haven't been able to bring my hd500x running, I don't know if it is because of the X or not. modprobe work's fine but I don't see it with

cat /proc/asound/cards

nor I see it in alsamixer.

hope this help, let us know how it goes.

Hi, I have good news.

We could patch the line6usb drivers and make my pod hd500x capture and playback in linux with kernel above or equal 4.9. I'm writing a guide on how to do it, when ready I will let you know. With a small change I believe it could work with pod hd pro, but I don't have one to test it.

Hi Hmoller,

Thank so much!!! I have a POD HD desktop and every time I'm dreaming with this solution. From time to time I search in internet to find anyone has a solution for that. Please let me know if you finish that guide. I wanna try to see if its will work with my POD.

Regards,

hmoller · August 10, 2017

Hi LuizMartins,

the guide is ready and the patch for pod hd500x is present in kernel 4.13. But, since I only have the parameters for the hd500x, it won't work in hd desktop. However, it should be easy to build the patch, I need the lsusb -v of the device. If you don't know how to do it, right after you plug your device to the system you should run in a terminal dmesg.That will produce at the end an output like this:

[ 8860.408050] usb 1-3: new high-speed USB device number 4 using ehci-pci
[ 8860.527576] usb 1-3: New USB device found, idVendor=0e41, idProduct=4159
[ 8860.527579] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 8860.527582] usb 1-3: Product: POD HD500X
[ 8860.527584] usb 1-3: Manufacturer: Line 6

what interest us is the idVendor (which should be 0e41, that's line6) and idProduct which should be similar to 4159.

store those numbers and the execute the following replacing idVendor and idProduct with the numbers you got in dmesg:

lsusb -v -d idVendor:idProduct

and give to me that output so I can prepare the patch.

Which kernel version are you using?

Hmoller,

My Kernell is 4.10 low latency. It's important update the kernel? Bellow the output of dmesg and lsusb:

Ok, it seems identical to pod hd500x so we will try with the same configuration. And since you have kernel above 4.9 it should be easy

The guide is in:

https://sites.google.com/site/hmoller/pod-hd500x-linux

change the lines where it says "HD500X" to "HDDESKTOP"

and the line:

{ LINE6_IF_NUM(0x4159, 0), .driver_info = LINE6_PODHD500X },

change it to

{ LINE6_IF_NUM(0x4156, 0), .driver_info = LINE6_PODHDDESKTOP },

this is to match HDDESKTOP product id.

try PATCH 1 and tell me how it works.

to know if it's working in dmesg you should see something like this (but with HDDESKTOP):

[ 9085.982607] snd_usb_podhd 1-3:1.0: Line 6 POD HD500X found
[ 9085.986607] snd_usb_podhd 1-3:1.0: Line 6 POD HD500X now attached
[ 9085.993332] usbcore: registered new interface driver snd_usb_podhd

which distro are you using? you can use alsamixer and select soundcard to make the audio use this new card.

Hi,

I get an error in process. Maybe i'm forgot something cause i isn't have much knowlege to do that. So i followed these steps but i get this error when i will compile the modules:

luizmartins@luiz-notebook:/usr/src/linux-source-4.10.0$ sudo make -C /lib/modules/$(uname -r)/build M=$(pwd) modules

I'm use kubuntu and i have the build-essentials and the kernel-headers installed. The kernel source i download from kubuntu ppa.

Searching on internet, it's seems a problem with Makefile, but i don't know how to fix this. I'll keep trying to solve this. Please, tell me if you have any idea what's i can do.

hmoller · August 14, 2017

I believe that the problem might be that you must run the command from the directory where te podhd.c is, in your case I believe is /usr/src/linux-source-4.10.0/kernel/sound/usb/line6/

try that and tell me how it works.

LuizMartins · August 16, 2017

You're Right. I execute the command from correct folder ( /usr/src/linux-source-4.10.0/sound/usb/line6/ ) and now compile without problem, but now i have issue with the instalation. I get this error when i execute make module_install:

INSTALL /usr/src/linux-source-4.10.0/sound/usb/line6/snd-usb-podhd.ko
At main.c:158:
- SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175
- SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:178
sign-file: certs/signing_key.pem: No such file or directory

I found in internet, its seems Ubuntu have a signed kernel and i need to generate a ssl certified. I look for this signing_key.pem file, but i didn't found. I trying some tutorials but i cant make it work. Im stuck again :( .

hmoller · August 16, 2017

I've seen that "error", but in my case the module was installed anyway, so continue and see what happens after modprobe.

look at this:

https://github.com/betolj/ndpi-netfilter/issues/38

https://github.com/patjak/mba6x_bl/issues/46

If it doesn't was installed look at this:

https://github.com/patjak/mba6x_bl/issues/54

tell me how it work.

LuizMartins · August 16, 2017

Its work man!! Finally!!!

I had seen these post before but in my situation, the module was not installed and the insmod command dont work. I lost hours trying to solve and in the end i simply copying manually the .ko files generated by make command (snd-usb-podhd.ko and snd-usb-line6.ko) into /lib/modules/ folder. <_< After that i load the modules with modprobe and works fine. I tested recording and playback with reaper and all works fine! In my case, the erro 11 didn't appear.

Thank you so much for this, now i can work with my notebook too :) :) :)

hmoller · August 17, 2017

Good news!!

Take into consideration that every time you update/upgrade your kernel you will need to compile and install it again.

Until kernel 4.13 you won't have any problem, but in 4.13 the pod hd500x was added and since you donÂ´t recieve the error 11 maybe another small change must be added.

We also need yout help, to help the linux+pod hd community we should include the patch in the kernel. Since the kernel updates are incremental, we should build the patch upon kernel 4.13.So, you will have to test the patch in kernel 4.13. I will reach you in PM to coordinate this.

LuizMartins · August 17, 2017

I will be happy to help. I will send you a email to keep in touch.

Hi,

I'm using Line6 TonePort DI-Silver with linux.

I found latest kernel support:

TonePort GX

TonePort UX1

Toneport UX2

from this site:

https://sbexr.rabexc.org/latest/sources//6b/f376d328e0c925.html

actually, I tested this driver in kernel_5.13.10-arch1-1 with archlinux, with my toneport di-silver hardware, like this:

$ sudo modprobe snd-usb-toneport

plug in the toneport di-silver to the usb port, led start to flash red, after a wile, led will turn off, then excute this:

$ echo "0e41 4144" | sudo tee /sys/bus/usb/drivers/snd_usb_toneport/new_id

the led will turn green, and it start to work.

plug in my electric guitar, it start to make sound for my guitar.

(if plug in the usb after the step adding "0e41 4144" to driver's new id, the led will keep flashing red, but the sound card can also work.)

but there's a problem: without any virtual amplifier, the toneport di-s sound card will always directly make clean tone of guitar from the right speaker channel when i play the guitar.

If I use virtual amplifier like "guitartix" with JACK, the guitarix will work good, I can setup JACK's sample rates or frames, it make the sound what I want, distortion, delay, reverb... from both left and right speakers, it's good, but the direct clean tone is still there from right speaker which is not uneccessary. I can't turn off the uneccessary clean tone or control it.

is this problem the same with TonePort GX, UX1, UX2 ?

how can I fix it?

Solaris235 · December 10, 2021

It's good to see someone working on linux support for Line 6 products.

Is this a native driver or will it work with wine.

I have a Pod HD500X, the edit software works fine through wine but it doesn't see the HD500X so I can't change or update any settings or sounds with out using windows.

Sound play back through the HD500X works fine natively on Ubuntu 20.04

Sound recording from the HD500X works fine natively on Ubuntu 20.04

It would seem we only need a driver to bridge the gap between Linux USB and the HD500X driver running in the wine environment.

Come on Line 6 you can do it if you try.

knstrock · November 6, 2023

hey guys? is anyone is trying to find the solution? or this case is unsolvable?

Hello esteemed community,

I've encountered a challenge trying to use Windows audio drivers for a specialized USB audio interface on the Steam Deck. Here's the series of actions and their outcomes:

Using Wine: I initially attempted to install the Line 6 Monkey software through Wine, hoping it would set up the required drivers. The software got installed, but unfortunately, Wine couldn't interact correctly with the audio device.
VMware Attempt: I tried installing VMware, but the system blocked this attempt.
VirtualBox Attempt: My attempt to install VirtualBox was also unsuccessful. The system blocked the installation, returning errors related to trying to write to protected filesystem partitions. Notably, during the VirtualBox installation, the terminal kept throwing multiple warnings about the inability to create directories in the /usr directory, indicating that the filesystem was read-only.
Multiple Reinstallations: After several tries to reinstall or upgrade VirtualBox and other packages, I was faced with the same issue: the filesystem would not allow any write operations.

Currently, the audio device is being detected by the system, but it doesn't function as expected due to the lack of audio driver support. I contemplated using Linux drivers directly, but there were complexities given the protected partitions of the Steam Deck.

I would greatly appreciate any insights or suggestions that could assist me in overcoming this hurdle. Perhaps some of you have encountered a similar situation and found a way to get Windows drivers working on Steam Deck, or there are methods to bypass the system's restrictions?
