Hi all,

Hi Leo,

this is the last try I make to solve my problem. I wrote everybody, in every site/forum, read everything, followed tutorials without any solution.
As written in the title, I have a Fast Track Pro connected via USB on Ubuntu 12.04 LTS, I have Ardour 5.1.0 and QjackCtl 0.9.3
The problem is after many, many tries, I have the signal coming from the card arriving in Ardour, I see the v meters move but I cannot hear any sound in the headphones or from the speakers.
The same happens both in Hydrogen and Rakarrack.
The last thing I did is downloading the fast-track-pro.conf file from Joe Giampaoli tutorial. Since it's for Debian, I've only downloaded the file and modified as per his instructions.
Then I modified it again as per instructions in this thread in Linux musicians' site.
I'm also in touch with Joe but until now I haven't found any solutions for this.

This might not be your preferred solution but I would try a _live_ CD/DVD/USB of latest ubuntu, kxstudio or similar to see if it works in later versions. If it works I'd definitely upgrade. If not your 12.04 LTS is becoming EOL in april 2017.

regards,
