Re: [FFADO-user] [I'm a user and need support] QJACKCTL not showing interface options

[Marc C. <mca...@st...>]

Hello all.

Just to inform you that I purchased a FA-101.   Plugged it in and all is great.    I have installed an SSD boot drive, installed Ubuntu Studio 16:04 LTD.
I am now delving in all the software included in the distribution as well as getting a better understanding of JACK.

I now a an FCA202 and FA-101 plugged into my new firewire interface card.  (will keep the FA-66 and see if I can identify the problem)

Thank you to Jonathan for all the support.   Hopefully I will be able to be off assistance to the group in the future.

That is mostly good news.  Of course the negative side is that it tends to suggest that your FA-66 is broken. :-(

I think running Ubuntu Studio would be a good first step because that distribution comes with things already configured for audio/video production use.  This includes a "low latency" kernel.

Give Ubuntu Studio a go, as you suggested.  Without seeing the error messages reported by jack it's impossible to say what the problem might be. 
I suspect it might be at least partly due to the use of the generic kernel (as opposed to a low latency kernel), but this is nothing more than a guess.

Hopefully Ubuntu Studio will provide a solid starting point and require fewer adjustments to get it working.
