Kellaway Posted December 15, 2013 Share Posted December 15, 2013 I've just acquired a Line 6 HD300 unit and at the same time am considering a change of OS over to Ubuntu Linux for various reasons like MS no longer supporting XP.. Has anyone out there used this combination? There is no mention of Linux in the Monkey downloads. I have very slow satellite broadband and have found the Monkey downloads so far painfully slow or even impossible as the biggest upgrade refuses to load the latest version. So I'm thinking Linux might make it totally impossible. I may have to take the computer to a fast broadband for downloads but if Linux does work with it this would help.

TheRealZap Posted December 15, 2013 Share Posted December 15, 2013 they are not line6 supported, and will not enable any line6 applications to work natively within linux. they are 3rd party audio drivers, that you can of course use of your own risk.

Yeah I think any drivers that you are gonna find are gonna be third party. I have never seen any pro audio manufacturer who supports linux..

fr2632 Posted December 28, 2013 Share Posted December 28, 2013 Hey Kellaway, I am a linux user too and I can confirm that if you install windows 7 on a virtual machine (virtualbox for example) it works! You can even upgrade the firmware/flash of your Line 6 HD300! I did it with my HD500x and I guess it should work with the HD300 aswell! Good luck ;) Quote Link to comment Share on other sites More sharing options...

andypierson Posted October 20, 2016 Share Posted October 20, 2016 I also use LInux. One method to still use Windoze is to download Disk2vhd (the one i have is 2.01) from sysinternals.com. This will allow you to create a virtual image of your Windoze computer. If you use VirtualBox then when you open the program uncheck the "Use Vhdx" box. Once that is done create your image, import to VirtualBox in Linux. You will need to do some config on memory, video memory, USB port sharing but I suggest you RTFM or check forums on VirtualBox. This only works if you have a Windoze pc still around. If you don't, find a friend that has one that is not in use and clone it (with the understanding they format that pc so you do not violate the EULA).

arthroppus Posted November 30, 2016 Share Posted November 30, 2016 I think it's a shame that Line 6 does not provide their software for Linux. The solutions using Virtual Box (or VMWare) are resource consuming. Quote Link to comment Share on other sites More sharing options...

jensverwiebe Posted December 12, 2017 Share Posted December 12, 2017 Hi folksI recently got a Line6 Helix LT and saw it is kinda usb-compliant at least on the mac.So i gave it a try on linux and got it run.I had to hack alsa to not try to read or set the fixed default 48kHz samplerate.Then i still had small soundglitches cause the usbrate does not follow, so i made a hack withan arbitrary value read from another working usb interface here too. ( implicite feedback not available ? )Result: it works fine with jack ( incl. midi ), setting up all 8 in/out and also aggregate it via alsa_in/alsa_out with my focusrite scarlett 6i6.Todo:Pure alsa does not work atm as i don't get the control interface setup to have a mixer, which should be a passthrough like on mac annyway.When i have time i wanna get rid of my arbitrary hack to read out properly the usb rate from the interface3 feedback endpoint.Perhaps it can be calculated other way or a timer is needed, not sure atm..Roundup: Helix (LT) is somewhat compliant on linux alsa, but needs some quirks. Perhaps such could be better supported in next firmware update./proc/asound/HELIX/stream0:LINE 6 HELIX at usb-0000:07:00.0-2, high speed : USB AudioPlayback: Status: Running Interface = 2 Altset = 1 Packet Size = 224 Momentary freq = 48005 Hz (0x6.0029) Interface 2 Altset 1 Format: S32_LE Channels: 8 Endpoint: 3 OUT (ASYNC) Rates: 48000 Data packet interval: 125 usCapture: Status: Running Interface = 3 Altset = 1 Packet Size = 224 Momentary freq = 48005 Hz (0x6.0029) Interface 3 Altset 1 Format: S32_LE Channels: 8 Endpoint: 3 IN (ASYNC) Rates: 48000 Data packet interval: 125 usCheers ...

shemeshg Posted January 10, 2018 Share Posted January 10, 2018 Hi, Just Startin' Will it be possible to post, the steps you have made to make Alsa recognize Helix speed correctlly? I guess I wil have to download ALSA and recompile it with specific exclusion of speed negotiation for the Helix, is that so? Will it be better for me to wait for it to be at the next ALSA release? Was it required any kernel changes required also? Thanks These are greate news, and I hope Line6 will make Helix more USB compliant, on next Firmware Update so it would work out of the box in OSX and Linux, with no driver or othe changes required. This will also assure that no matter what changes would Apple or Linux do, Helix would remain rock solid. Quote Link to comment Share on other sites More sharing options...

Hi The steps i made are very simple atm., also i only recompile the snd_usb_audio.ko for the runninng kernel. I'am awaiting some hints from alsa devs to make the ep->freqn requested in the right way, but thats not yet solved.

The line where i add 5Hz to the usbrate may vary for you, i recommend to have another usb-interface plugged it the same port and get the runtime rate from /proc/asound/<other_interface>/stream0 ( sound must be played thru this to see the runtime parameters ) I will post when i have a clean solution and will try to bring this to the kernel backports then. Btw: 'am not sure if the OSX behavior can be called fully class compliant, but at least there you can get 48kHz without an additional driver. Other interfaces at least allow to read and set the samplerate in a not vendorspecific way. Would be nice Line6 could reach out for possible Linux users/buyers here ;) The final goal would be to have this on alsa too + later can choose the other available samplerates. Hope never dies :) Does this help ? ... Jens 2 Quote Link to comment Share on other sites More sharing options...

JACK is required since it is not plays directly using ALSA and PulseAudio, However, Jack sink works greate. 2. It will be required to recopy snd_usb_audio on every kernel update. But it is huge benefit being able to Re-Amp and not to require all of those XLR cables Thanks Shemeshg 1 Quote Link to comment Share on other sites More sharing options...

As well is the working midi, which allows you to use the miditemo depending delay timings + patch changes etc.. Just prepare an "all time patch", we need not to change kernels such often ( i hope, ask Intel :P) ) If you like you can post your experience in the alsa mailing lists too. More users rise the interest for developing a full implementation. Sidenote: using pulse-jacksink can disturb jack freewheeling which is for example used by Ardour (stem-) export. If you experience oddness, just deactivate for this usecase. ( pactl unload-module module-jack-sink / pactl load-module module-jack-sink channels=2 ), i use prepared scripts for load/unload in the linux mint cinnamon scripts applet ) Cheers ...

Thanks Shemeshg Initially you would not need to get a new kernel source, if snd_usb did not change. If in doubt, check the changelog. The makefile i posted always uses : KVERSION = $(shell uname -r) aka uses the headers of the active kernel. So just recompile that part. If you absolutely need to renew all: Actual: https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.4.116.tar.gz The kernels are always to find in : https://www.kernel.org/pub/linux/kernel/v4.x/ Or you clone the main repo ( git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git ) and checkout the wished tag and patch it. ( you can also cherrypick sound/usb ) Compile snd_usb_audio like described formerly. Full kernel: Don't forget to check its setup before compile, i use: cp /boot/config-`uname -r` .config make oldconfig make menuconfig Set lowlatency + timers to 1000Hz + HW timers used ( will be active if the former config was configured like this already ) Then compile typically with: make -j `nproc` LOCALVERSION= deb-pkg Jens 1 Quote Link to comment Share on other sites More sharing options...
shemeshg Posted February 24, 2018 Share Posted February 24, 2018 Hi this solved it (it seems some dependencies of snd_usb changed since the syslog with `tail -f` notified that snd_usb is .114 and not compatible with 116] Thanks Shemeshg Quote Link to comment Share on other sites More sharing options...
jensverwiebe Posted February 24, 2018 Share Posted February 24, 2018 Hi this solved it (it seems some dependencies of snd_usb changed since the syslog with `tail -f` notified that snd_usb is .114 and not compatible with 116] Thanks Shemeshg Hi Shemeshg Perhaps i was not clear enough. If you change the kernel (-headers), you have always to recompile the module else you break the dependencies. KVERSION = $(shell uname -r) assures you link to the active one. You may have just copied the former compiled snd_usb_audio to 4.4.116, this will not work. Syslog with `tail -f` notificatien implies this. What can work is using a newer or older linux/sound/usb as long as you compile it against KVERSION. This may give you an advantage in fixed components, but also may break some other if it also depends on other sound changes. So staying in the 4.4.xxx is a bit safer. I tested up to 4.10.xxx will work also, but does not give benefits for helix. ( but for the other line6 drivers ) Matching the source to KVERSION is indeed the best option, as you get backported stuff/fixes too. Hope this clarifies it ....

Just unpack in kernel sourcedir and run. Pls test. Unfortunately i still could not catch an expert on the usbrate thingie, so as long as we must patch this is more convenient at least. Only you must get the desired kernel src still,, i tested with 4.4.119 ( wget -c https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.4.119.tar.gz ) Cheers ...

Such can be using hardwaretimers or other relevant settings in alsa. It makes sure the snd_usb is configured same as your active kernel.

Make sure to stay inside the gotten sourcedir usb dir. In your case it should be cd /home/johan/kernelbuild/linux-5.1.15/sound/usb Or: Get this patch and scriptset from me: www.jensverwiebe.de/Other/audio_patching.tar.xz Unpack into your kernel-src, run script right from that dir ( all explained in the README ). Btw: Someone took my patch and commited it partly to alsa, so it might show up upstream anytime soon. Jens Quote Link to comment Share on other sites More sharing options...

Here are the steps to follow: get the Ubuntu 19.04 kernel source (it should be easy to transpose it to your system) git clone git://kernel.ubuntu.com/ubuntu/ubuntu-disco.git download Jens' patch and unpack it into the kernel source folder cd ubuntu-disco wget www.jensverwiebe.de/Other/audio_patching.tar.xz tar -xvf audio-patching.tar.xz cd audio-patching if you can, plug a usb interface into the usb port you want to use for the helix, play some sound and get the runtime rate cat /proc/asound/<other_interface>/stream0 you should get something like this: Playback: Status: Running Interface = 2 Altset = 1 Packet Size = 224 Momentary freq = 48002 Hz (0x6.0010) Interface 2 Altset 1 Format: S32_LE Channels: 8 Endpoint: 3 OUT (ASYNC) Rates: 48000 Data packet interval: 125 us Capture: Status: Running Interface = 3 Altset = 1 Packet Size = 224 Momentary freq = 48002 Hz (0x6.0010) Interface 3 Altset 1 Format: S32_LE Channels: 8 Endpoint: 3 IN (ASYNC) Rates: 48000 Data packet interval: 125 us the Momentary freq line gives you the runtime rate Open helix_clock_patch.txt: Find the following line + ep->freqn = get_usb_high_speed_rate(rate + 5); // ugly helix hack Edit it to match the runtime rate that you found, in my case: + ep->freqn = get_usb_high_speed_rate(rate + 2); // ugly helix hack If you have a Helix, you'll have to change both occurrences of USB_ID(0x0e41, 0x4244) to USB_ID(0x0e41, 0x4241)) the usb id of your pedalboard can be found using cat /proc/asound/HELIX/usbid run Jens script with admin rights and apply all changes sudo ./helix_patch_and_module_replace.sh plug your Helix into your computer, it should be recognized by jack as a USB audio interface now (working only for 48kHz) In case of a kernel update, you'll have to make the same changes to the new kernel: checkout your current kernel branch git checkout Ubuntu-<kernel-release> you can check that your source matches your current kernel uname -r git show run the script again and apply all changes, you might have to unplug and plug again your Helix Quote Link to comment Share on other sites More sharing options...
