Re: [alsa-devel] Line 6 Helix quirks
Hi I verified on my hx_stomp with the latest driver and I can confirm tha the quirks works here Sadly I don't have an helix to verify it
What model it is? you can try to recompile the kernel adding the line with you usb device to the
see my patch
https://lkml.org/lkml/2019/7/1/850
+ case USB_ID(0x0E41, 0x4244): /* HELIX */ + case USB_ID(0x0E41, 0x4246): /* HX STOMP */ + case USB_ID(0x0E41, 0x4248): /* what kind of HELIX ???????? */

Hi,
I'm attempting to use my Helix with the newish 5.3.x kernel. It isn't working. Looks like the quirk isn't enabled for the idProduct (4248) of my Helix. My Helix's firmware is 2.81.0. I have yet to compile the kernel to see if adding the id is enough. Thanks. If you need any more info, please let me know.
dmesg gives:

Back to the Helix once more .....
I already informed Nicola about latest Line6 firmware 2.8 ff changes.
All Helix devices seem to get a new product id due to the new core changes.
Additionally we have now an endpoint 5 for HID support ( applied dump ). Not sure what we can make out of this
cause a lack of investigation time. The audio endpoint descriptors are unchanged.
The problem with not working implicite feedback stays, so i still use my arbitrary 48005 Hz hack.
Without slight pop would ocure in audio, but still with this hack every 20 minutes i get a slight distortion which
is no surprise.
Can someone shed light here if an implicite feedback device should show the exact momentäry fequency ?
Should i see also the 16.16 feedback format ?
I looked through all code and 'am still stunned where the sync
fails.
Btw: i have also attached ioreg information from macOS if this helps someone to dig deeper. I dumped driverless
"usb compliant" mode here with integer outcome for a quick overlook.
This so far ... Jens
Hi Jens, in my hx stomp with 2.82 firmware the USB id is the same and I'm not experiencing any glitch. Also some people on line6 confirm that the patch is working for hx stomp. If on helix the situation is different you should submit a patch.

Without slight pop would ocure in audio, but still with this hack every 20 minutes i get a slight distortion which
is no surprise.
Can someone shed light here if an implicite feedback device should show the exact momentäry fequency ?
Should i see also the 16.16 feedback format ?
I looked through all code and 'am still stunned where the sync
fails.
Btw: i have also attached ioreg information from macOS if this helps someone to dig deeper. I dumped driverless
"usb compliant" mode here with integer outcome for a quick overlook.
This so far ... Jens

Hey Nick
The diff is a bit meanigless this way, do "sudo lsusb -vvvv -d 0e41:4246"
Then the device is opened and you should get some more info. Anyway, this will not bring
any new insight i think. I have to wait for a true usb expert.
Exept for the HID interface ( for key cmd's ) the Helix is fully the same descriptorwise.

Hi Jens, in my hx stomp with 2.82 firmware the USB id is the same and I'm not experiencing any glitch. Also some people on line6 confirm that the patch is working for hx stomp. If on helix the situation is different you should submit a patch.

Back to the Helix once more .....
I already informed Nicola about latest Line6 firmware 2.8 ff changes.
All Helix devices seem to get a new product id due to the new core changes.
Additionally we have now an endpoint 5 for HID support ( applied dump ). Not sure what we can make out of this
cause a lack of investigation time. The audio endpoint descriptors are unchanged.
The problem with not working implicite feedback stays, so i still use my arbitrary 48005 Hz hack.
Without slight pop would ocure in audio, but still with this hack every 20 minutes i get a slight distortion which
is no surprise.
Can someone shed light here if an implicite feedback device should show the exact momentäry fequency ?
Should i see also the 16.16 feedback format ?

Sorry, I didn't have time to compile a kernel until yesterday. I built the attached patch against 5.4.12 and it is working great with JACK. I have a Helix Floor running the 2.82 firmware.

OK, then could you give a bit more description of the patch as well as your signed-off-by line? It's mandatory for merge to upstream.
thanks,
