Re: Motu M4 Linux compatible?

If you want do this, please be aware that one of the workarounds is activated only for the Motu 16A by comparing USB vid and pid values of the device. If you want to activate for your M4 look at these lines: + if (chip->usb_id == USB_ID(0x07fd, 0x0004) || + chip->usb_id == USB_ID(0x07fd, 0x0005)) {...

Re: Problem with Mackie ProFx10v3

There is only one problem left: the changes are not persistent, every time I turn the PC off and on again I have to unplug the USB connections, run the code and plug the devices back in for everything to work. Could you explain to me how to make the changes permanent? Ah.. I was under impression th...

Re: Problem with Mackie ProFx10v3

Again, I ain't no expert on kernel modules, but it appears that there's a problem if two (audio) devices want to load/use the same module in the kernel. This may or may not have to do with the fact that one device needs an option that the other doesn't... My advice: do NOT connect the Piano via an ...

I have a problem:

Code: Select all

modprobe -r snd_usb_audio
modprobe: FATAL: Module snd_usb_audio is in use.

Try to unplug all USB audio devices before unloading the module.

... the results are always the same, the Roland piano works perfectly as soon as I plug it in, the Mackie ProFx10v3 never works.

Please post dmesg output after plugging in ProFx10v3. It will show if quirk is indeed was applied.

Re: Motu M4 Linux compatible?

Switched to motu m4, in general it works, but you will get the the periodic bitcrush effect (about every 2s) creeping in from time to time, need to power off the unit, wait a bit and power on again and it is usually gone, restarting pipewire works as well. Tried the quirk 0x220 but seems to be unre...

Re: Problem with Mackie ProFx10v3

... I read a thread in this forum from someone who says they managed to get it to work. I have tried the solution you propose but I have not achieved anything. If you have several USB audio devices connected, then you need something like this: options snd_usb_audio vid=0x0a73 pid=0x0023 quirk_flags...

Re: [SOLVED] - Mackie ProFX10v3 problems

JFYI: latest LTS and stable kernels have a workaround for this issue, so they probably should work out of the box.

Maybe you need to update firmware or try a different USB port or cable?

My theory here is that the device may be stuck somehow at Full Speed mode and won't expose UAC2 configuration to the host as there is not enough bandwidth. You can check this using lsusb for example:

Code: Select all

lsusb -t -v

Re: USBPre 2 Troubles :/

Your device has only 1 configuration and it is UAC1. Not sure why as the manual indeed says that it's UAC2 compliant and should support up to 192kHz under MacOS. Maybe you need to update firmware or try a different USB port or cable?

Re: USBPre 2 Troubles :/

Please post dmesg messages appeared after issuing usb_modeswitch command. Also it would be nice to see device descriptors:

I've found a weird behaviour when I start the computer with the module with quirk_flags=0x20 set in options.
The mixer is recognised but no output comes from the usb interface and jack generates a lot of xrun.

Are there any errors in dmesg? Could you also try quirk_flags=0x200?

Re: Presonus 1810c | Ubuntu | sample rates are missing

Or you can also try these module options instead:

Code: Select all

options snd-usb-audio vid=0x194f pid=0x010c device_setup=1

I've also tried the following options with snd-usb-audio

Code: Select all

modprobe snd-usb-audio implicit_fb=1
modprobe snd-usb-audio autoclock=0

Please try quirk that disables clock selector manipulations:

Code: Select all

modprobe snd-usb-audio quirk_flags=0x20
