Hi,

thanks for sharing your issue. It is a weird problem, some are affected, others are not.

See also this thread at the ardour forum:
https://community.ardour.org/node/5751?page=1

there's one person who uses it fine with Fedora 22, but others on avlinux and UbuntuStudio who have the same playback problem I have.

And on my Mint 17 I have never ever had a single issue.

There's also an old patch here, but I read that it was implemented in the kernel (kernel.org grabs the ALSA git since a while).

would be great if someone could shed some light :)

thanks!

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.

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,
