NEED Linux users with Helix / Helix Lt / Helix Rack /Helix something

Recommended Posts

Hi All,

 

I created a patch for Linux Kernel 5.3 to enable HX stomp/Helix

 

I need some help to confirm that is working properly.

In particular would be really helpful if you can try the kernel 5.3 and confirm the USB ID for Helix devices

 

case USB_ID(0x0E41, 0x4242): /* Line6 Helix Rack */
case USB_ID(0x0E41, 0x4244): /* Line6 Helix LT */
case USB_ID(0x0E41, 0x4246): /* Line6 HX-Stomp */
case USB_ID(0x0E41, 0x424a): /* Line6 Helix LT - firmware >= 2.8 */
 

This is displayed in dmesg when the device is discovered (open dmesg -w and then plug the device)

 

[  322.404503] usb 1-6: new high-speed USB device number 13 using xhci_hcd
[  322.531804] usb 1-6: New USB device found, idVendor=0e41, idProduct=4246, bcdDevice= 2.00
[  322.531806] usb 1-6: New USB device strings: Mfr=1, Product=3, SerialNumber=2
[  322.531806] usb 1-6: Product: HX Stomp
[  322.531807] usb 1-6: Manufacturer: LINE 6
[  322.531808] usb 1-6: SerialNumber:    3021888
[  322.535789] usb 1-6: parse_audio_format_rates_v2v3(): unable to retrieve number of sample rates (clock 16)
[  322.535907] usb 1-6: parse_audio_format_rates_v2v3(): unable to retrieve number of sample rates (clock 16)

In particular if the device is supported the last two lines will show as unable to retrieve number of sample rates set it to default as 48Khz

 

What I need is a list of helix like devices and the list of idVendor, IdProduct.

 

Can you help me?

 

Also for Line6 did the new update to support the new Mac Os X bring some news for Linux Users as well??

 

Thanks

Nick

Thanks a lot for this! Running Linux 5.4.2-1 (manjaro) and HX Stomp was detected with the your listed vendor and and product ids.

 

However I still can't get it working as an input with any audio application (ardour or audacity), but it shows up as an option.

I also have no PC output through the stomp (using only headphones, no speakers currently) with applications like spotify. alsamixer reports it as a soundcard with no controls.

 

My GUI sound settings lists it as "HX Stomp Analog Surround 7.1" and shows output levels being sent to the stomp, but I get nothing through the headphone out.

Hi you probably are using pulse audio you should use jack. I don't know the setup for mangiaro in Ubuntu I'm using the utility from kxstudio  (CATIA) and it setup a pulse audio plugin called Alsa sink to route the audio from pulseaudio to alsa

That fixed it! Had never used jack or any sort of advanced audio configuration on Linux before, thanks for all your help on this issue.
