Hi David,
Does this happen with all CDs or just with one CD? How many 'wav' tracks are queued at the moment?
If the first 'wav' track in the compression queue is corrupt in any way, that will prevent any further compression happening. You can check this by:
1. Go into the WebUI, click on the little 'Cog wheel' icon to open up 'Settins & Stats' window,
2. Then click on the 'Spanner' icon to open up the Debug window.
3. Click on the 'Clear' button to clear the Debug window.
4.. From the front panel, select 'Compress Now'
5. In the Debug window you should see a string of chacacters; the album name and track name should be visible.
6. Delete that track and go back to step 4 and repeat.
You might have to delete the entire album.
Regards,
Peter.
