fix playback speed to be same as record speed

I record a track. i play it back and it is at a higher pitch.
how can i fix it so the record speed and playback speed are the same?
I am new to ardour, I like it, but I can’t tolerate the pitch change.

Hey! I am back on the forum :slight_smile:
OK, your problem is that your soundcard records at one sample rate and jack is set to another so the playback is at another sample rate.
What is the card SR ? can you change it to what you want ? and when you set it to what you want, start jack with the same SR.
