[LAU] Focusrite Scarlett 8i6 recognised, inputs work, but no output - Mint 18

Dear all, I have been using my Focusrite Scarlett 8i6 for a couple of years without issues on a Linux Mint 17 laptop. I can use the sound card only via Qjackctl (no ALSA out of the box). Now, I have a new computer (shuttle xpc slim) on which I installed Linux Mint 18. The sound card is recognised by both Jack and cat /proc/asound/cards. It even correctly appears in the system sound preferences, which did not happen in Mint 17. However, while the inputs work, there's no output. I've tested with a bunch of audio software, such as Pd, Ardour, Hydrogen, etc.. Interestingly, if, immediately after testing with Mint 18, I plug the sound card back to my Mint 17 laptop, at first, the sound card does not produce output. I have to power off the sound card and re-plug it, then it works. I would need this to work only with Jack, I'm not looking for an ALSA fix. I know in the past three years there has been a few ALSA patches to make this range of Focusrite work, and I think most of those patches are now in the mainline kernel. Although I'm not familiar with this. Does anything I could try come to mind? [SYSTEM INFO] Mint 18 kernel: 4.4.0-31-lowlatency alsa-base 1.0.25 libasound, etc.. 1.1.0 thanks in advance! best wishes, -- Marco Donnarumma, Ph.D *Performing bodies, sound and machines**Universität der Künste Berlin* http://marcodonnarumma.com 4w33534643646 --
