soundbooth CS4 will not record files

I am having an issue with Soundbooth CS4 not recording a file. I can open the record box and select my audio source (Alesis USB mixer in this case) but when I hit record nothing records. The record button does highlight however no audio is record or wave form shows.... Ive tested the setup (Alesis USB mixer into my MacBook Pro) with Audacity and it works fine, all settings are correct with the Soundcard and with OS X.. Ive been recording into Audacity, saving, then opening in Soundbooth to do processing. While this works, I would like to get my moneys worth out of Soundbooth and do all my recording, processing, and editing in the same app. I've attached a photo of the screen for you to review...

Thanks in advance for any help you can offer.

All playback through the device is working as expected??Does the playhead and Time counter appear to be recording - ie, do you have a file of the correct length, but full of silence, or does record simply seem to be ''stuck'' ?

Thanks for your reply. Yes, everything else on Soundbooth works fine except the abilty to record. I edit synicated radio shows and have to time out for hard breaks and the time has ever been off.. Effects, multitrack, all playback works fine...

When I click the record button in the record box, the stop and marker icons highlight but nothing records, timer does not move, meters do not move/show levels...

Hmm.?So when playback is fine but record just hangs, it's often a clocking issue.?Is this device one of the MultiMix systems??If so, what version of OS X are you running and have you updated the drivers for the device??I know there were some problems with Alesis support on OS X 10.5.5 or 10.5.6 and they released some updated drivers on their website to address the problems.?That would be my next recommendation.

If that fails, we may want to create a custom Aggregate Device with limited inputs to troubleshoot this.?You can do this by launching ''Audio MIDI Setup'' (located at /Applications/Utilities/) and chooseing ''Aggregate Device Editor'' from the menu.?Here you can create a new device and specify only a specific set of inputs and outputs from your Alesis, choosing which one you'd like to act as the Master Clock.?After this is created, select the new device in Soundbooth's Audio Preferences and see if you get different behavior.

We do have an Alesis MultiMix 8 around here, but it's currently locked in a coworker's office who's on vacation until Monday.

Adding the Aggregate Device in the midi set up worked!

Thanks!!
