I have met the same problem with the Scarlett 18i8. Some times, I have inputs and outputs level. But some time, the input is ok but no outputs. If I restart the Scarlett soundcard (I turn off the power) then, most of the time, the output level is back. Some times, the level seems to be a little bit low, but the balance is not OK (everything is on the left or on the right). After a restart, everything is back. 2 times out of 3, the sound card works fine. I use Fedora 24 with a RT kernel from CCRMA. ----- Mail original ----- De: "Marco Donnarumma" <lists@xxxxxxxxxxxxxxxxxxx> À: "linux-audio-user" <linux-audio-user@xxxxxxxxxxxxxxxxxxxx> Envoyé: Mardi 9 Août 2016 17:48:48 Objet: 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 -- _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
