Thanks for your reply.

It seems there was a conflict because I had Reaper open at the same time. When I closed reaper I was able to playback using Audacity.

Still trying to work out how to do the routing so I can record from the playback channel - can you give any guidance there?

cheers

Thanks - however I am still having audio problems on playback. There is popping and crackling in the audio.

I currently have my audio editing program, Reaper, running and I also have the quicktime player open. The quicktime player is using Fireface UC Analog (1 & 2) for playback.

Reaper is configured using ASIO Fireface USB drivers.

I am getting this crackling whenever I play the audio with Reaper also open. The crackling becomes less when I close Reaper but it is still there.

I am Running Windows XP  on an intel iMac using bootcamp.

I am going to try using the Fireface on the Mac instead but I am feeling pretty disappointed with these issues so far. I was hoping that I would be able to use this reliably on Windows.

There definitely seems to be come conflict going on in my system.

Any help appreciated.

please elaborate more on this, does it mean bad drivers in general for BootCamp !?

regards S-EH

Hi guys,
I have some problems with my FF but with the advices of Timur, win xp bootcamp works better than snow l?o.
So i think bootcamp seems to not be a problem.
In other hand, most of advices seems to be for macbook, i don't know with imac...

Hello again!

Since I last posted on this forum I have bought a brand new laptopp with 4 GB RAM running Windows 7 x64.

Guess what - same problems as before!

When I play audio via a media player (using the RME interface) everything is fine UNTIL the reaper window becomes active. When the Reaper window becomes active a horrible stuttering/crackling occurs in the audio.

The stuttering/crackling immediately disappears if I switch to another appication window or even just open a dialog box within Reaper.

My installation of Reaper is using all default settings - except for the DEVICE which is set to ASIO.

This problem has nothing to do with recording or playback within reaper, it occurs when the reaper window becomes the active window even when there are NO TRACKS present.

Sorry,  can you explain what you mean by "This kind of usage is simply not supported"?

I do this all the time on MacOS! I use my audio interface to record a radio podcast which often involves playing youtube videos etc... So (for example) I will open a web page and start playing a youtube clip and the playback channel gets recorded to a track and voila - we have a recording!

This is not supported?

I don't understand your statement and can only assume there is a misunderstanding. As I said - it works perfectly well on MacOSX.

Let me describe a typical work flow. I record my show using a number of tracks in Reaper.

I have one track set aside for my microphone.
I have another track set aside for my skype input (which is fed in via another computer)
I Have one track set aside for my "playback" channel, so I can play clips from youtube or a DVD, etc... and have that audio recorded on the fly as part of the show.

The problem centers around the usage of the playback channel, but this problem DOES NOT occur on Mac OSX - only on Windows.

To reiterate - the audio goes into the horrible stuttering mode only when the reaper window is active.

Typically I would be talking on my podcast  - "blah blah blah ... now I'm going to play you a clip from youtube.... here we go" ... the clip starts, I reactivate the reaper window and YUCK the horrible sound appears again.

Hope that explains it (:

With all due respect Isaac, I find your reply a little haughty and a little rude and totally unhelpful.

I think I explained my problem pretty clearly, so I'll wait for someone who really wants to help to respond, cheers (:
