Thanks again to everyone who is helping me out. I try to work with and digest everything that people suggest which is why I do not respond right away. Let me fill you in on a few problems I have had over the last day or more. First: when I was trying to start Jack up with qjackctl, I would get a window which read: # [Window] # Error - JACK Audio Connection Kit: # # Could not connect to JACK server as client. # - Overall operation failed. # - Unable to connect to server. # Please check the messages window for more info. The message window had a lot of text, some of which was: # Messages: # 20:19:52.805 Patchbay deactivated. # 20:19:52.817 Statistics reset. # 20:19:52.870 ALSA connection change. # Cannot connect to server socket err = No such file or directory After using GOOGLE to try to locate an answer to this question, I came across this solutions: delete {$HOME}/.jackdrc delete {$HOME}/.config/rncbc.org/QjackCtl.conf make the user that you are trying to run Jack under a member of the "audio" group. (I am running Fedora 20 if that matters, maybe other distributions do not have an "audio" group. With that, Jack was able to start again. HOWEVER ... I have lost some of my M-Audio cards functionality. qjackctl's [Connect] window under the Audio tab USE TO DISPLAY THIS: On Sat, 2 Aug 2014, Ivan K wrote: > > == == Readable Clients/Output Ports > == == - system > == == capture_1 > == == capture_2 > > on the right, and then on the left, I see: > > == == Writable Clients/Input Ports > == == - system > == == playback_1 > == == playback_2 > == == playback_3 > == == playback_4 > == == playback_5 > == == playback_6 > == == playback_7 > == == playback_8 BUT NOW, since my problem with starting JACK up, the "Writable Clients/Input Ports" box is blank. I lost my eight "writeable ports" and I am presently working to get them back. Any tips would be appreciated. Incidentally, what do these eight playback connections represent. The "M-Audio Audiophile 2496" only has three outputs, left and right analog and S/PDIF. And so do these playbacks 1 through 8 refer to some sort of mixing channels in the firmware of the Audiophile 2497? To repeat, though, I have lost these playbacks 1 through eight in the Writable Clients/Input Ports box. How can I get them back?

Oh my card is definitely the "M-Audio Audiophile 2496". It says so on the box. And the commands aplay and arecord list the device as: card 0: M2496 [M Audio Audiophile 24/96], device 0: ICE1712 multi [ICE1712 multi] Subdevices: 1/1 Subdevice #0: subdevice #0 > [...] > zita-a2j -d hw:0,1 -r 48000 -p 256 -n2 -c 2 > alsa_in -j spdif -d hw:0,1 -r 48000 -p 256 -n 2 -c 2 I will report on my success and failure with the zita-a2j/alsa_in commands soon.
