Samplerate mismatch

Some days ago with my old KXStudio 14.04 configuration I've got when starting Ardour via the terminal the message:
Code: Select all
convolution: samplerate mismatch preset:48000 host:44100
Now with Debian 9 the same message. The strange thing is that my Interface is set to 48kHz and also in Jack / Cadence I see 48kHz, even the Ardour Project is 48 kHz. I also can change the rate of the interface via changing the rate in Jack. So everything works, but where does this message come from???
I googled and find basically only my own threads or very recent ones from 2018 *lol*.
Qtractor shows the same in the info window.
When I set the interface and JAck to 44.1 kHz I get also:
Code: Select all
convolution: samplerate mismatch preset:48000 host:44100
This makes no sense at all ....

Hi,
Have you started any applications that use JACK before launching Cadence?
I don't use Cadence but I have had it happen if I launch Carla or use jalv they will start their own process with JACK D-bus, then later I start JACK and 'jackdbus' is already running and you can end up with 2 jack processes at 2 different sample rates... That's probably not what's happening to you but it's just a guess, Does your session have some kind of convolver plugin running?

No, it happens if I just start Cadence and an empty Ardour project without anything directly after booting and there's nothing else running.

FWiw, I have been seeing that too, using Cadence and Ardour from KXStudio... I have not noticed any audible problems.

Ah... that's good to hear.
Thanks!

Same thing here but it doesn't seem to be causing any issue.
Cheers

Or perhaps *not* to hear?

I've been getting the same error, but they unfortunately end with Segmentation Fault, and I can't run programs like Audaciy, Guitarix, Jalv.Select...
I've uninstalled everything convolver related, one by one, LOL, and the problem is "zita-convolver" from the community repos (arch linux). Guitarix won't start without it, I've removed zita-convolver but leaving other packages related to it (using
), and Guitarix wouldn't start
Code: Select all
guitarix: error while loading shared libraries: libzita-convolver.so.4: cannot open shared object file: No such file or directory
All the other convolver packages didn't seem to make any difference. My system is also set to 48khz.
Maybe there's a way to make zita-convolver skip this samplerate check (as it is totally wrong, LOL)??
