Flacon (flac + cue)

It is always a pain to convert cue+flac files in Linux.  Most methods are done in command line.  This is until I found Flacon.  A GUI tool that can split a FLAC file into tracks and convert them into a desire format.

You can either get the software from its main site (https://flacon.github.io/) or from PPA (https://launchpad.net/~flacon/+archive/ubuntu/ppa)

CUE+FLAC playback with Audacious

I finally found the solution for playing back CUE+FLAC files! Here is the solution. First you install audacious, and then install its extra plugin package called audacious-plugins-extra. After, run audacious and open its preference. Under the audio option, deselect all options under the Format Detection. That is it. You can now play CUE+FLAC files!
