[LAU] jack persistent connections FAQ link

by Peter P.

Hi dear list, http://jackaudio.org/faq/persistent_connections.html mentions that there is a way for persistent connections without using a GUI program. The page says about this way to do it that "The semi-automatic, script-based one is described in another FAQ." but I can't seem to find it. What could be meant here? Thanks! P

[LAU] The new GUI of QjackCtl renders QjackCtl unusable

by Ralf Mardorf

Hi, since I'm using Linux nowadays more or less only for mastering with imported audio files, I didn't notice a disastrous change of the qjackctl GUI, that seemingly already happened a while ago. The "Connect" window is replaced by a "Graph" window. Complex connections are never easy to track visually, but at least the old "Connect" GUI is clear, concise, well-structured and readable. The new "Graph" GUI is seemingly an attempt to draw virtual Pollock pictures, see https://i.imgur.com/3TFRGZF.png, even the text became unreadable. However, even without way too small text at tolerable zooming for the graph, in one colour on nearly the same colour and even without shadow effects, the way the routing is displayed by default renders qjackctl unusable. I'm aware that it is possible to move the items, I also can move my computer, synthesizers, mixing console, effects, but for good reasons I don't want to move anything from one to another place, if my intention is to restore a session and to make music. Searching for the last usable qjackctl release, I found out that the last version providing the usable "Connect" GUI is 0.5.2. [rocketmouse@archlinux tmp]$ cat /var/log/pacman.log | grep qjackctl | grep grade | tail -4 [2019-01-29 01:12] [ALPM] downgraded qjackctl (0.5.5-1 -> 0.5.4-1) [2019-01-29 01:13] [ALPM] downgraded qjackctl (0.5.4-1 -> 0.5.0-1) [2019-01-29 01:14] [ALPM] upgraded qjackctl (0.5.0-1 -> 0.5.3-1) [2019-01-29 01:16] [ALPM] downgraded qjackctl (0.5.3-1 -> 0.5.2-2) Am I the only one who wants to get back the old GUI?

[LAU] Selling RME Digi 96/8 PAD

by bernard

Hi there I am selling at low price an RME Digi96/8 PAD with its daughter board *AEB4-I* allowing to record 8 tracks at a time. This is a PCI card not PCI-e, and works very well under Linux systems. You can watch the specs on the 'old' RME site : http://www.rme-audio.de/old/english/aeb/aeb48i.htm I can't use it no more because I use now a laptop exclusively. If interested, make me an offer and I'll check for shipping (I live in France). I will also supply a multijack cable 4 stereo<->8 mono. Thanks

[LAU] zita-n2j waits 10 seconds?

by Peter P.

Hi, trying to use zita-n2j and depending on its different buffer sizes or jackd buffer sizes it prints Waiting for 10.0 seconds... and does not play back audio. This message seems undocumented in the man page and a I wonder under which conditions it arrives... Thanks for all ideas! P

[LAU] mod-host (or lilv) issues: failed to map segment from shared object

by Jeanette C.

Hey hey, since my system upgrade (Arch Linux) last night, I have issues with mod-host or liblilv. The following error - or variants thereof - appears: lilv_lib_open(): error: Failed to open library /usr/lib/lv2/lsp-plugins.lv2/lsp-plugins-lv2.so (/usr/lib/lv2/lsp-plugins.lv2/lsp-plugins-lv2.so: failed to map segment from shared object) can't get lilv instance resp -102 With the calf vocoder it's libfreetype.so.6 and the segment from shared object. Can anyone hint at the origin or point to good possibilities? I did reinstall mod-host and the calf plugins just now, in case something got mixed up. No change before and after.

[LAU] [OT] 8-port USB hub

by Jeanette C.

Hey hey, I am currently looking for an 8-port USB hub to connect a lot of USB MIDI gear, a computer keyboard and a braille display. I think all of them will work with the lowest bandwidth of 12MB. My system has USB1 and USB2. USB3 will connect, as I found out. Due to some devices requiring a little power over USB an externally powered hub is required. Does anyone here have experience with similar scenarios and hardware? Can anyone suggest a device or series from experience, please?

Re: [LAU] USB interface for backing up old tracks mastered on cassette

by Jordan Muscott

Thanks to Jeremy, Will, Ralf and everyone else who replied. I've tgken it all onboard. I've got a Yamaha-KX550 cassette deck which I'm happy with as the source. I have to admit I'm not convinced an entry level sound device won't be plagued by noise or other quality problems even if the converters it has are decent, but I'm yet to decide how much money I am prepared to spend :) All the best, Jordan.

[LAU] memlock limits not set correctly?

by Bill Gribble

This has just popped up on my audio machine and I am not sure what is going on. It's probably a change somewhere in PAM or GDM config. If anyone knows what's up I would appreciate a clue. Thanks!
