Linux avl-mxe-live 5.16.0-18.1-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 5.16-26~mx21+1 (2022-03-29) x86_64 GNU/Linux
Based on the comment above, I would expect this to be functional in 5.16 but doesn't appear to work for me?
When I run alsamixer the only control I have is for the clock source... Can someone fill me in on what I might need to do to get my focusrite to function?
I have attempted to disable the memory card mode by pressing 48V and powering on for 5 seconds.
I can configure jack to use the focusrite and can start jack, but when I enable record track in ardour I get no signal in the software. The focusrite displays signal from my mic, however. And yes, the input is selected correctly in ardour i'm not that much of a newb. And I have tested an alternate audio interface which does work (Zoom H5).
Many thanks for any help and for the work on this!
If you don't see the MSD control, you haven't enabled the driver. See the instructions at https://github.com/geoffreybennett/alsa-scarlett-gui especially the USAGE.md Prerequisites section.
Enabling that from a live CD could be interesting! The problem is that you need to specify options to the snd_usb_audio module when it gets loaded. Usually you'd put this into e.g. /etc/modprobe.d/scarlett.conf & reboot. But unless your live CD has persistent /etc (seems unlikely?), that's not going to work.
Two ways to do this I think:
- On the kernel command line, add a parameter "snd_usb_audio.device_setup=1,1,1,1" (I'm guessing this based on the kernel documentation)
or
- Boot with no USB audio devices attached, do "lsmod | grep snd_usb_audio" to make sure it's not loaded, create the modprobe file, then plug in your interface.
Good luck!

Geoffrey.
