First of all pardon me if this isn’t the right place to talk about this issue
Today i’ve been working on two different sessions @ 48KHz and have the same issue on both of them, after some recording (3 tracks) and handling the regions “suddenly all recorded audio changes its pitch”, at least what i didn’t bounce before that switch, its very weird and it affects from that point on and wont change back even after restarting Ardour.
This has never happened to me before so i don’t know if its a bug or some other thing related, this is my setup and how it happened, i’ve changed the sample rate today and i suspect that could be at some point the reason of all this.
Phenom II 955 on Asus MB
8GB Ram @ 1600MHz
RME HDSP 9652 conected via ADAT only to:
Focusrite Saffire Pro 40
OS: AVLinux 5.0.3
DAW: Mixbus 2.0.7
Jackd: jackd1 1:0.121.3avlinux-1
So, the Saffire Pro 40 is working on Standalone mode as a ADAT preamp, and it can be programmed only through Windows (if there’s a way to do it on Linux please tell me), so to change the Sample Rate from 44.1KHz to 48KHz i had to do it on Windows.
So back at AVLinux 5.0.3 i switched the HDSP to 48KHz also, then in Jack the same and started it, it all works fine (today i’m recording a friend for a video track so… 48KHz it is), so in the middle of the workflow, sounds an almost imperceptible click then all audio shifts its pitch a little so it all sounds weird and out of tune, minutes later just out of curiosity i oppened a .wav file @ 44.1KHz and i actually sounds cracky and out of tune also so thats why my guess is this is a sample rate issue, but… why is this happening? all hardware is working at 48KHz and the recording is at that sample rate, can any body help?.
