No sound on Logic Pro X

Additional:

If you haven't turned on all the advanced features of Logic pro X your Audio Prefs screen will look like this...

If you have turned on all the advanced features of LPX then your Audio prefs screen will look like this...

In both the above screenshots my audio device (A Motu Ultralite Interface) is selected for both input and output devices... and Core Audio is Enabled.

Make sure your Audio device (whichever you have or internal audio if you don't use an external Audio Interface) is selected for both the input and output devices.. and that Core Audio is enabled .

Talke a screenshot

Capture some of your screen

Press Command (⌘)-Shift-4, and then drag the crosshair pointer to select the area. Hold Shift, Option, or the Space bar while you drag to resize the selection area. To cancel, press Escape (esc) before you release the mouse button.

.......of your Audio preferences in Logic's prefs and post it up using the camera icon in the Reply box here....

To help troubleshoot..

1. Delete the user preferences
   You can resolve many issues by restoring Logic Pro X back to its original settings. This will not impact your media files. To reset your Logic Pro X user preference settings to their original state, do the following:
1. In the Finder, choose Go to Folder from the Go menu.
2. Type ~/Library/Preferences in the "Go to the folder" field.
3. Press the Go button.
4. Remove the com.apple.logic10.plist file from the Preferences folder. Note that if you have programmed any custom key commands, this will reset them to the defaults. You may wish to export your custom key command as a preset before performing this step. See the Logic Pro X User Manual for details on how to do this. If you are having trouble with a control surface in Logic Pro X, then you may also wish to delete the com.apple.logic.pro.cs file from the preferences folder.
5. If you have upgraded from an earlier version of Logic Pro, you should also remove ~/Library/Preferences/Logic/com.apple.logic.pro.
6. Restart the computer.

Delete the CS Prefs too...

Then test....

Doesn't matter if you have or haven't changed any settings... did you use the link I posted?

You need to check Logic's audio preferences and see what is set as the output device. Logic runs independently from the computer it has it's own settings that it uses.

I haven't changed any setting and it will also only let me select external midi when I make a new track.

This indicates that your Audio interface is not selected and/or Core Audio has been disabled..

Check, as Pancenter said.... Logic's Audio preferences and ensure your Audio device is selected and Core Audio is still checked.

Make sure Logic's audio preferences haven't changed.

The link tells you how to set your audio interface.

Thanks Nigel,

I forget about Core Audio being selected, there have been several posts where Core Audio has been mysteriously de-selected.

Look at Output Device, do you really want the output set to HDMI, set it to the correct output.

Monitor's speakers? Hence HDMI output?

Never tried doing it via HDMI myself...
