No sound in Ardour 5

WilhelmusB · December 25, 2016, 10:19am

On my Toshiba laptop Satillite C870-CL. Windows 10 home 64bit, Intel Celeron B830 1.80GHz. Realtec Sound High Definition Audio.
I would like to know Ardour.
I get so far no sound.
I work with Mint 17. The Bashee and VLS player I get sound. The sound I see movement in the columns from Ardour.
At Synaptic is a green square for Qjacketl, jackd, libjack-jackd 2-0, vlc-nox and aurdor.
What should I do to get sound with Ardour.
From the Netherlands. Message translation made by Google.

I forgot to report. I have in Ardour looked at how and what I then with VLC and Banshee is no sound to hear.

@WilhelmusB: you better describe your problem in Dutch, this automatic translation sucks huge balls. I barely understood what do you want to ask and I’m still not sure if I got anything right.

Bedankt alexhtebassist.
Ok ik type het in het Nederlands,
In Ardour krijg ik geen muziek te horen. De metertjes VU balken gaan wel op en neer.

Ik krijg twee meldingen op mijn scherm.

Warning: Your system has a limit for maximum amount of locked memory.
This might cause Ardour to run out of memory before yout system runs uot of memory.
You can vieuw the memory limit with 'ulimit-l’and it is normally controlled bij /etc/security/limits .conf
Aurdor could not start JACK
The are several possible reasons.
You requested audio parameter that are not supported
JACK is running as another user,
Please consider the possibilities, and perhaps try different parameters.

Wat opvalt zodra ik JACK of Ardour wil gebruiken/verkennen het systeem, het CPU gebruik vaak op meer dan 80% gaat draaien. Ik zie dat aan het icoontje, schermpje rechts onderin het beeld.
Wat doe ik fout. Of heeft u een link waar ik een oplossing kan vinden.

@WilhelmusB: thanks for detailed description. Sorry, I can’t reply in your native language, but still can read it a little.

First, you need to set up JACK either within Ardour (less flexible, no external control on parameters, less parameters to choose) or separately via a controller application (preferred way, there are Qjackctl and Cadence for that). Install an application you find most appealing and set up your audio there. I suggest using Cadence since it does much more than just audio server configuration. When setting up JACK, consider your use case: if you’re recording live sound, you most probably want low latency, so set up your buffer at 256 samples or lower. If you’re mixing with heavy processing, you need to set up a bigger buffer, like 1024 or even more samples. Also the thing that matters is periods/buffer value. Generally, it should be set to 2 when using PCI cards and to 3 for USB interfaces, but every case is unique.

You can also google for memlock limit and set it up to be sure Ardour won’t eat up all its memory limits.

Remember that generic kernels aren’t really suitable for lowlatency applications due to several technical reasons, so you should go for a realtime or lowlatency kernel.

I hope that helps. If you run into any more issues, do not hesitate to ask.

Dank je voor je antwoord. Ik kan het lezen kost moeite maar het gaat.
Voorlopig is mijn enige doel klanken van een keybord met een geluidsprogramma bewerken.
Met JACK lukt het nog niet. Het is niet eenvoudig omdat ik ook een nieuweling ben met Lunix Mint.
Bij mij bovenste regel: JACK Audio connectinkit [(standaard)] gestopt.
Bij berichten krijg ik een lijst onder andere de opsomming
Kon niet verbinden als client met de JACK server.- gehele toepassing gefaald. enz
Daar maar eens verder zoeken.

Dit is voor mij erg lastig.

It’s clear from log that JACK can’t allocate and lock memory. Is your user in “audio” group?

WilhelmusB · December 30, 2016, 9:56am

Thank you for the commitment
Through all the tinkering I have no sound in Linux. Fortunately still sound in Windows 10.
Go and try to solve a Dutch forum.
A healthy and prosperous 2017 and will keep you informed of this expedition.

alexthebassist · December 31, 2016, 10:15am

@WilhelmusB: thanks!

Also, this part has some information on where to dig:
