Sample rate will not change

Logic refuses to change its sample rate from 44100. This happened all of a sudden last night when I opened a session I was mixing at 48000 and noticed it was playing back at 44100 (as it sounded flat and slow, obviously).

When I select a new sample rate from the Audio menu there is a click, Logic thinks for a moment, then there is another click, and Logic thinks a little longer then a brief spinning rainbow. When it has finished the sample rate is still 44100.

I am using the built-in audio driver on my MacBook. I have imported the audio from a 48000/24bit pro-tools session. I'm used to working in 44100 so I may have missed something obvious, but it seemed to be working for me yesterday.

Urgently need this working. Any help much appreciated thanks.

One thing you might try to do, is to unplug any headphones / devices from your audio inputs and outputs, ESPECIALLY if they are digital.

This helps in re-setting the sample rate using the internal sound card.

I've just noticed this today, and found the solution...

I was convinced that you could set the sound card's sample rate independently of Logic and I believed I had been running it at 192 KHz before, during and after a Logic session. Whether or not Logic would temporarily change this to 44.1 I can't say for sure, but I'm pretty sure if it didn't keep it at 192 during, it certainly reverted to it on closing Logic. But now, this isn't the case, and I'm finding Logic sets it and then keeps it at 44.1

The solution...

Set your project's sample rate to the desired rate in File > Project Settings > Audio

My gripe about this is that it's not trivial to change this once you've done a lot of audio work because Logic doesn't seem to understand that an audio sample at 44.1 is the same temporal length as one that's at 192, so it time compresses them (+and the pitch goes up+) if you up the sample rate. I would imagine the opposite would be true, although I haven't tried it.

So you really need to decide on the project's sample rate from the start, and stick with that (+unless you are just working with Apple Loops and Midi, in which case everything seems OK+).
