I have an 8 year old basic M-audio Fast track. I used the XLR in with a SM57 on PPC112. Linux and audacity for recording.

I want to stick with Linux and change to the headphones out for a bit.

What would be a good way to record directly out from the 5150III headphone jack? The YouTube videos for this seem quite good and the general sense is yeah, it works fine.

I think my Fast Track simply isn't up to the job. I had a listen and isn't quite taking it well. Also some problems like Qjack not detecting it.

So what would be a fairly affordable solution for an audio interface USB into Linux like Ubuntu 17? Something that is well supported and Qjack can recognize?

No idea, but look at the Ubuntu Studio forums, I am sure Linux users can help. I know my Firepod is supported under Linux, but yours might also be.

Did you try ALSA?

I suspect because of its age that support is virtually gone for some of its features. You one you liked with is an newer version.

I am thinking about getting a Focusrite Scarlett Solo 2nd Generation but I need to talk more with the linux people on probably a dedicated linux place.
