That all looks fine.
I'm trying to find something that doesn't

Could you post a short sample to illustrate the problem in WAV format. Just a few seconds is sufficient. (see here for how to post an audio sample viewtopic.php?f=49&t=72887)

Also, from Audacity "Help menu > Audio Device Info". Save that and attach it to your reply.

What's the goal? What are you doing that resulted in the error? Reading for an AudioBook? Podcast?

What did you plug into the audio ports? In detail. Model numbers.

I'm with Steve. Post an audio sample.

Steve, the audio is attached (it's me counting to 10) and the audio device info is enclosed below. Hope this helps.

What's the goal? What are you doing that resulted in the error? Reading for an AudioBook? Podcast?

What did you plug into the audio ports? In detail. Model numbers.

I'm with Steve. Post an audio sample.

Koz

I'm using audacity to record a podcast that I'm recording through a rig that's plugged into the rear line in port. I doubt the external equipment is the issue (remember it works 100% with audacity in Windows). But for completeness I'm using a couple of condenser mics connected thjrough a behringer xenyx x1204 mixer.

[djrlosthisname]

Did you offend your computer in some way? Forget its birthday?

Koz

I did forget to call that one time...

[kozikowski]

I doubt the external equipment is the issue

So do I, but as nobody has been able to turn up the problem so far, we need to look in an expanding ring of possibilities. Beware of microscopic misdirection. Concentrate so hard on the problem you miss other valuable information. AKA the 10,000 foot view.

I followed an internationally respected engineering consultant around once as he was doing a survey. I brought home that he was doing exactly what I'd be doing, except he didn't take shortcuts, make assumptions or leave anything out.

Effect > Change Speed.

Convert the 0.6 second clip to ten seconds and it appears to be close to the right rhythm and meter (attached).

But there's a lot of other junk in there and there is no convenient sampling rate change that can account for the change.

Wild-eye, blue sky observation: This is what happens when you try to play a sound file in Audacity encoded with an advanced technology (M4A, AAC) and don't install the FFMpeg software that knows what those formats are. Audacity by itself has no idea and plays them as if they were uncompressed, plain sound files. They're not. So a 2:1 compressed sound file plays at double speed.
