Hi folks,
I bought an HX Stomp the other day.
One thing I don't like about my setup is that the iPad I use for backing tracks needs to be connected to the HX with a cable (whether USB or 1/4" jacks).
Since it's already 2020, I can't help but wonder how much more convenient it would be to use Bluetooth. For example, Yamaha THR-II supports that.
Then I realized I have an unused Raspberry Pi, and I can try using it as basically a Bluetooth-to-USB-to-HX receiver.
I know Raspberry Pi is popular among folks who build DIY home audio systems, including Hi-End ones, so figured it can handle the task.
I don't mind more cables connected to the HX Stomp, but I don't want to have a cable connected to the iPad, as there's always the risk of pulling that cable and dropping the iPad on the floor.
However, turns out the Raspberry Pi can't play audio through HX Stomp via USB — I just can't hear any sound when I choose "HX Stomp" as the output device.
I found an article on Raspberry Pi forum on how to patch the Linux kernel [nerd alert!] to work with Line 6 products.
After spending a few hours setting up my Raspberry Pi, recompiling the kernel, etc., sadly I have to report that it didn't help.
Looking at the configs and the source code of the kernel modules, it appears that it only supports some models of the POD HD era, and not the Helix family.
Adding support for a new family of devices goes well beyond my knowledge of Linux, and beyond how much time I'm willing to spend on this project if I work on this alone.
I hope this post will attract attention of someone who's more skilled in Linux than I am, and will find my idea and findings useful.
Or maybe even someone at Line 6 will see that it's a cool idea to add Bluetooth and/or will implement the required kernel modules? Who am I kidding...
