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 
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.
