Disappearing Audio

Hiya Bill!

What are you running your sound out of and into?  (ie Interface to monitors or ?)

Can you give us an idea of what and how you have your playback system setup. 

Thanks

Also, what are your settings at in Sonar for Record/Playback Buffers?

Your issue sounds similar to what I sometimes experience - I can be working away on a project, hitting the space bar to start and stop playback when all of a sudden there is a very strange noise like a squeel and there is no audio.  Usually if I hit space bar a couple of times and retrigger playback I get audio again.

Hey, guys.  Sorry I didn't give enough info on the first pass.

I use a V-Studio 700 for the audio interface.  I run ASIO.  All audio goes through the V-Studio; meaning, the V-Studio monitor levels control all audio from the PC and if the V-Studio is not powered-on, there is no audio from the PC.  Primary monitors are KRK Rokit 6s and Alesis Studio Ones (and Bose headphones).

My PC is a Sweetwater Creation Station optimized for the studio: 8-core machine running Windows 7 in 64-bit, Sonar running in 64-bit (but using bitbridge for some things), 12GB RAM.  No other applications running simultaneously.  No spyware or malware.  PC not connected to Internet except to update music software.

What I meant about opening something in stand-alone was this:
• All Sonar sound stops: soft synths, wavs/audio tracks, audio tracks fed by external MIDI synths, etc.  I cannot hear vocals or instruments I already recorded.  I cannot hear MIDI or soft synth tracks.  Meters in Sonar indicate audio is playing.
• Even though Sonar audio stops, audio in general still works.  I can play CDs in the PC, hear the sound on videos, and open a soft-synth in stand-alone mode outside of Sonar (e.g., Ivory, Vienna) and hear the sound.  PC/windows sounds still play.  Internet sites still play audio.  It is just Sonar audio that quits.
• This is not the same issue as MIDI stopping, which was a problem that somehow went away over the last few months.
• I will have to look at my audio buffer when back at the studio.  It seems like I recall moving it from 500 to 750, but honestly can't recall without looking.
I do use a lot of soft synths (Hollywood strings, Vienna, Ivory, RealGuitar, RealStrat) and some like Hollywood take a lot of memory and CPU; however, this problem happens sometimes in projects that don't have a lot of VIs—and I don't think I use way more than anyone else doing pop music with sweetening or light orchestration.
Thanks again for replying.

Beagle, Interesting, thanks.

is interesting, altho i don't use loop or auto punch-in (at least not on purpose).  what are the shortcut keys for these? maybe i am doing something by accident

I get the same thing.  It' really pissing me off.  Is this only happening in  Expanded?  I have to constantly change audio outputs to and from to get my audio back.  On my laptop my interface just disappears and I have to reboot.  Has this  been reported?  Is this going to be X1's "motorboating"?   If so Cakewalk will deny it exits for about a year and you'll have to upgrade to the next version to get it fixed.  Then it will be something else.  I think Cakewalk is just not interested in the pro or semipro market anymore. 

Glad to hear we have identified something in common regardless of the setups. Now for a fix hopefully  

Has anyone generated a log with Cake on it yet?  Ill do one, not sure if we can link this post to it or not.

are you guys using 32bit or 64bit X1?  which version of X1?  I think we have different soundcards at least.

me:
win7x64
sonar X1d Producer Expanded 64bit
MOTU Ultralite Hybrid MK3

interesting.  I assume this advice is the same for win7?

Win 7, 64 Bit here.  Never had the problem just creeped up (Expanded related?, who knows but that was the last thing I did a while back.  

I did find that it appears if you try to do things as the transport is in motion, I believe this is when you can trigger the problem. Messing with certain plugins, deleting plug ins, messing with ProChannels settings, etc...  is when it appears to me that it happens. Not sure which ones though. Im all Sonar-Nothing Else added to computer.

Im running MAudio FTU and monitors directly out of that.

I see it is happening with many others out there with much more expensive/elaborate systems as well. So it appears its not an isolated problem.

No doubt you've,gone to preffs,and hit apply a few times?

It's just,I MUST do this EVERY TIME I open Sonar to get sound with my laptop,and it brings sound back,when all the meters are showing,BUT there is NO Sound.

And any thing stand alone works fine,just NO sound with Sonar.

With me its computer specific[or seems to be] as my listed desktop,NEVER has had this happen [yet].
