[PATCH 0/1] ALSA:usb-audio: Disable Arturia Audiofuse 16Rig

[Phil Willoughby]

I am working on properly supporting this device, and I have published that
work in progress here:

Link: https://github.com/WillerZ/arturia-af16rig-driver

I intend to continue working on this driver, test it fully with all the
sample rates & clock sources that the device supports, and then contribute
the necessary changes back to the mainline kernel. This will take at least
several weeks because I need to source additional hardware to do that
testing.

Because the device has 32 input channels we will need the patch to support
that merged before it can be properly supported.

This patch chain prevents snd-usb-audio from claiming the device.

This is necessary because the startup sequence of snd-usb-audio puts the
Arturia Audiofuse 16Rig into an invalid state from which it cannot be
recovered other than by disconnecting the external power; even the
front-panel on/off switch stops working.

[PATCH 1/1] ALSA:usb-audio: Disable Arturia Audiofuse 16Rig

[Phil Willoughby]

There's an out of tree driver which works for some use-cases here:

In general, we don't care much about the out-of-tree driver.
If it's upstreamed, of course we'd love to help.  But this kind of
change is no-go.


thanks,

Takashi

I'm happy to work on patches for an in-tree driver.

It would need the patch chain you sent me that replaces the
hardcoded channel max with MAX_CHANNELS and makes the channel mask
64-bits, because it has 34 channels.

I'd also need to add one or two new quirk flags or device-id matching
branches: which approach is preferred?

If it's confirmed to work, I can submit and merge this beforehand.

Well, it's hard to tell without comparing both changes...


thanks,
