I have a suggestion for AVLinux. My regular user was unable to start jackd (via qjackctl) until I followed the instructions I wrote for Gentoo at http://audiodef.com/gentoo/proaudio/ProAudioForGentoo.php under the sections “System Settings For Audio” and “Testing Your System”. I think these instructions should be added to a file that gets placed on the desktop of a fresh install - or better yet, have a little script run during the install to set this up.
I’ll repost my suggestion in the appropriate place if someone can tell me where that place is.
Having a problem with Ardour on AVLinux now. When I open an existing project, there’s no output. When I connect Ardour’s master outs to my system’s main inputs (an Onyx mixer), the master meter in Ardour shows a continuous warbling signal in the meter bars whether the project is playing or not, but there is still no audio.
On another project, I get wild distortion in the red (and there IS audio. Terrible, terrible distortion), but the signal fades when I hit stop.
Looks like a feedback loop, but where? In the first project I tried to open, I cut ALL connections and then reconnected ONE track. No effects, plugins or VSTs. This still happens.
You should not be having trouble running jack and having to change anything, if it worked correctly on the LiveDVD/USB it should work correctly on the install, If it’s not working OOTB with realtime permissions something is definitely wrong from the get go. AV Linux is not perfect by any stretch but OOTB JACK permissions support is normally not an issue. The problem you are having with the arrangement that loads and maxxes out the meters is almost certainly a plugin problem. I have seen this with Calf LV2’s in particular where an arrangement with older Calf versions was opened with newer Calf plugins on the system, if not Calf it is almost certainly a plugin causing this.
By Onyx do you mean a Mackie Onyx? In AV Linux you must add your user to the ‘disk’ group in order for firewire devices to work properly. I suggest you come on over to the AV Linux forum and we’ll help you get this straightened out, In the meantime you may want to update Wine from here: http://www.bandshed.net/checkinstall/wine_1.3.7avlinux-1_i386.deb. In my experience this new version is a little better behaved than the 1.3.2 that comes on the AV Linux ISO. Did you try JACK with your onboard soundcard first? That would be an indicator if JACK or ffado are causing trouble with the Onyx. There is pretty detailed firewire HowTo here which may help as well: http://www.remastersys.com/forums/index.php?topic=516.0
Pop over to the AV Linux forum, take a deep breath and we’ll help if we can…
