Audio pitches down when headphones are plugged in

Hi,

I’m running Cubase 12.0.52 on a MacBook Pro M1 Max, OS Ventura 13.3.1. I’ll try to explain the issue as best as I can.

There’s a huge problem with audio when it comes down to change the audio driver. I usually opt for a Focusrite Scarlett 4i4, and everything works fine. When I unplug that to work with the headphones jack output (maybe because I’m away from the studio), sometimes it doesn’t show any outputs. Meaning, the audio built-in is selectable in “Studio setup”, but when I set the outputs up in the “audio connections” window, it doesn’t show the built-in L and R channels.

I still don’t understand what’s the correct way to solve this, but I found out that unplugging and replugging the audio jack magically makes the outputs appear. It’s either that or doing the same thing with the Scarlett. I know it’s confusing but usually, playing it like that solves the issue, it’s not ideal but enough while I wait for some kinds of updates.

Lately, however, something new came up. If I don’t have the Scarlett connected and outputs are showing up correctly, and I play cubase via the built-in speakers, audio plays smoothly (it’s just a piano VST in the session I’m using now). If I plug in the headphones (without Scarlett), the audio suddenly pitches down and slows down A LOT. I thought that was some kind of mismatch with the sample rate, but there are no issues in the “project setup” window.

What is happening here? Anybody has any clues?

EDIT: I just found out that changing the Sample Rate to another value and back to the original one solves this. In my case, it was at 96 kHz, I switched it to 48 and then back to 96. However, this is highly far from ideal, it worked on that session because I did not have any recorded audio (just one piano VST), I honestly don’t want to do that if I have audio tracks as it might mess the project up converting the audio.

Hi,

Make she the Sample Rate of your project matches the Audio Device’s Sample Rate.

This is what it looks like. Seems fine to me.

Yesterday, I used the Scarlett and quit cubase, with the audio interface set as that one.

Today, I ran Cubase again, with headphones plugged in. Sound was coming out of the speakers, weirdly. I unplugged and replugged the headphones, now it’s going through them, but I have the same issue as usual (sound is slowed and pitched down).

This is seriously annoying. What am I missing?

EDIT: again, changing the the project sample rate to another one and back to the original makes time and pitch issues disappear, but I’d hardly call that a solution
