It could be that you burned it as a data disc or mp3 CD instead of an audio CD. Re-check your settings to make sure it is an audio CD. Hope this helps.

Hi and welcome,

I'd say, something is wrong with your settings. And if the factory replicates from your master disc, there is a high probability the resulting discs will not play in a standard audio CD player.

Hopefully someone familiar with wavelab essential will have some advice.

Can you list the settings in question?

for example: 16-bit / 44100 Hz sample rate

Some of the disc manufacturers offer mastering services, but you'll pay hourly for the service. In which case, I'd rather pay a mastering engineer of my choosing. That way I could pick someone who has delivered the kind of results I like from comparable music. The plant may do great work, who knows? I'd want to hear some before and after samples of their work and still have final approval on my project.

Thanks.....

Sample rate is 44.1 khz
Bit resolution and stereo/mono channels are greyed out when you open a montage in wavelab, I think it's 16 bit by default.

All the wav files have already been mixed/mastered by a friend, all I need to do it import the files into wavelab and burn a master CD for the replication plant.

I've had this problem doing quick demo mixes where I "mastered" and burned the project myself. In my case it was always one particular cd player (of the older, cheaper variety) that wouldn't play the disc. Have you tried several different cd players and gotten the same result? Maybe try burning at 1x if you're not already doing so -?
EDIT: I can't remember what app was causing this - it was a standalone "burning" program that I wanted to use so I could just generate the cue/bin files and burn copies at will without booting up the DAW. Still no idea *why* it was happening, or what vital piece of code was being left out, (It was supposedly "finalizing" the CD) but it was something important only to older lower quality players, obviously...
I installed CDRWin instead and it works like a champ. I doubt any of this applies to your situation since I can't imagine any version of Wavelab having trouble with this sort of thing.
