[PlanetCCRMA] What Am I Missing?-- playback and capture sample rates do not match (44100 vs. 48000) F10 and F11

Hi list,

When I first installed PlanetCCRMA on F10 64 I was able to run my
M-Audio Fast Track Pro at 48000Hz under the default settings that
PlanetCCRMA gets setup with.  I have some sessions in Ardour that were
recorded at 48000Hz, so I know I wasn't imagining this. At some point,
when I was in a hurry to record something in the field, on a laptop
that is running F11 32 I started up Ardour and it prompted me that the
sample rate rate was set to 48000 and that I was trying to create a
44100 session in Ardour and If I would like that changed. Since I was
in a hurry I just went with it, thinking It would be easily resolved
later. Ever since I have not been able to get Jack to start the
M-Audio FTP in 48000 under F10 or F11. I have run out of things to
check and am wonder if I am missing something since it did run at
48000 at one time.

The driver for the audio interface is snd_usb_audio.

I have nothing in /etc/alsa/alsactl.conf that specifies anything.

There isn't anything special .asoundrc file

And there is nothing special in /etc/asound.conf or /etc/alsa/alsactl.conf

Is there some other place I should be looking? Since I can get it
changed under f10 or f11 and it did run once at 48000, I and guessing
I am and hope so also.

Below is the message output from qjackctl

Both f10 and f12 give the strange error that it can't load
/usr/lib64/jack/jack_firewire.so. Of course The M-Audio FTP is a usb
device so it shouldn't need that. Not sure why it would look for that.

For the most it was much of a problem because it was at a good enough
rate for me to work with, but now I am faced with the situation that I
need the higher rates.

Thanks,
