I push play, but it doesn't play

I recorded a song, and I want to play it, but when I push play nothing happens. What do I do?

Its a song with 5 audio tracks, straight in with a mic. I have an amd athlon (tm)64 x2 dual core processor with on board sound (I think). I am running music creator4 with windows xp.

Another question. How did you record 5 tracks of audio with an onboard factory soundcard if you didn't play it back?  To record the second track, and so on, you would have had to use the playback/record at the same time to hear the first tracks you already recorded to multitrack it...... no?

Does that "64" mean it's a 64-bit processor? Weren't there 2 versions of MC 4, one for 32-bit and another for 64-bit? If so, which verson did you install?
This is from a Cakewalk support page: http://www.cakewalk.com/Support/FAQ/x64_FAQ.aspx#8
8) What Cakewalk programs can I install under a 64 bit Operating System?
Any application that is specifically supported under Vista or Windows 7, has also been approved to function under Vista x64 or Windows 7 x64 (in 32-bit emulation mode). This means that if an application such as: Guitar Track Pro 4, Music Creator 5, or SONAR Home Studio 7 does not list 64-bit OS support on he packaging or system requirements, this is only referring to native 64-bit support. Unlike SONAR, the for mentioned programs contain only 32-bit versions of the program, whereas SONAR contains separate 32-bit and 64-bit applications on the disc.
If you are running a 32 bit program under an x64 Operating System you should expect it to work just as well as running under a 32-bit OS; however, you will not see the same benifits as a SONAR x64 user, such as increased RAM utilization. 32-bit applications are still limited to accessing 2-3GB of RAM even in a 64-bit environment.
 

Music Creator 4-it says Record at up to 24-it quality.

 
Audio 24-bit depth has nothing to do with whether your processor is a 64-bit processor.
Sometimes these numbers in the names of computers mean nothing, like it's 'Model # 64', but if it means that your processor is a 64-bit processor, that could be pertinent to your problem.

Gotcha.
Go to 'Options>Audio' at the top and make sure your input and output drivers are still selected, and that your sound card is listed and selected as both the Recording and Playback Timing Masters.
Check what the driver mode is. MME is the oldest, slowest driver; WDM is the better choice, and if you have ASIO available, see if you can select that.
Open your Windows mixer and ensure that your ins and outs are selected and that the volume sliders are up and unmuted.
Make sure that "IDT Audio 2" is not the S/PDIF output.

Recording and playback timing master should be set to your soundcard.  If you do not know if you have ASIO drivers, then you probably do not.  I would say to stick with MME for now, for even though they are the slowest, they are usually the most dependable.  Check your inputs and outputs within the app to be sure that the signal flow is correct.  When you switch back to MME drivers, you are going to have to run the wav profiler again.   Windows Mixer does have volume control but I'm not completely sure if we're referring to the same thing.  It's the big-ish control-board looking thing.  On most systems you can get to it by right clicking on your little speaker icon in the system tray and click "open volume control" and it pops up.  Make sure nothing is muted in there.   Also when in there, go to options> properties, and you can check setting for playback and for recording there.

You sure have a lot openned on that screen, i would close WMP first, then second look under the general and advanced tabs and see what is under record and playback timers.

I wonder what IDT audio 1 and IDT audio 2 are?  hhmmm it seems that you only have wave file on one side of the track, could it be that that is the other side from what you are listening to?
TRy checking IDT audio 2 and see if it plays.

also all tracks are set to play thru Audio 1 plus the master strip as well. HHHmmm

Cool that is what i was thinkin'

IDT audio is my sound card, is that right? So instead of IDT as my input i check master bus?

Ace, that was kind of a joke, but not really...
It's recommended to send your audio track's outputs to 1 or more buses before they go to the sound card's main output. It looks like you have a single bus in your screen shot, but you can add more if you want.
You might have multiple guitars in a song; send them to a bus labeled 'Guitars'; same with vocals; send them to a bus called 'Vocals'; drums; ditto.
That way if you want an effect on the vocals but not on the guitars, you can insert an audio effect in the bus's effects bin so the effect will act only on the vox. Same with guitars or any other instrument you want to effect.
