Hi all, My little community FM radio broadcast audio project is coming along nicely, my thanks to all here who have offered insight into some of the quirks of JACK. I have a couple of questions about jackd's verbose output. Question 1 : Where can I find descriptions of the various flavors of message...

SOLVED! Under "Studio Controls" > Extra Devices > Select Device to Edit I found "Headphone plug in Action" set to "Switch outputs to Headphones" for my devices. Setting the Action to "No Action" did the trick. Because I keep a pair of headphones plugged into t...

I have been digging into this . . . as if I have nothing better to do with my life . . . I find in /etc/init.d/alsa-utils this: # Description: This script stores and restores mixer levels on # shutdown and bootup.On sysv-rc systems: to # disable storing of mixer levels on shutdown, # remove /etc/rc[...

Hi, I hadn't tried Loki's suggestion of nrestore, sorry, I hadn't noticed it. So I just now tried it and it does not do the job. The sound card remains muted. This was not the behavior when I was using the same card with straight-up Ubuntu 22.04, it seems to be a Ubuntu Studio quirk. Perhaps another...

Hi merlyn, Thank you for the tip on giving zita-j2a and -a2j JACK names. For the amixer suggestion, I think I am looking at a roadblock, I don't know if there are workarounds. Your suggestion to use amixer is something I could work with, but apparently the target card, a Presonus Studio 24c has no c...

Hi I am launching QjackCtl from the command line like this: /usr/bin/qjackctl --active-patchbay= /home/kpov_tech/Desktop/Settings/KPOV_Test_Live_MCR_In.xml & and I am getting these errors: Cannot connect to server socket err = No such file or directory Cannot connect to server request channel ja...

I was mistaken -- sudo alsactl restore does not restore the saved settings with all the sound cards unmuted. One of the two USB audio interfaces "wakes up" with its output muted and it has to be unmuted manually in System Settings > Audio. How can I force the PC to unmute all the sound car...

Thank you Erlkönig. For JACK I do load the cards with their names, such as zita-j2a -d hw:CODEC -r 48000 -p 256 -n 2 (Pity that QjackCtl does not display those names in Graph . . . ) But that doesn't do anything on the muted-after-reboot issue that ALSA causes, so I am guessing that you are doing so...

ThatJackElliott

Hi, yes -- two sound cards (well three, if you count the computer's motherboard sound card), two Stereo Tools, but one QjackCtl. The alsactrl restore operation does work. I don't feel that users should have to consider that the OS will mess with their settings, to me this is something that I should ...

ThatJackElliott

Agreed that the default behavior is questionable, (especially since this is Ubuntu Studio after all) but there it is. I do have reason to have more than one soundcard so a text-name workaround sounds like it would be nice to implement.

ThatJackElliott

Merlyn, an update. Yes, sudo alsactl store followed by sudo alsa restore does the job. I can use it in a startup script called by QjackCtl. Thank you for the suggestion. Oh, btw, whatever is causing this PC (Ubuntu Studio) to wake up with one or more ALSA Playback cards in mute state is unknown. I t...

I steadfastly deny that I have a "Repel" option.

If that image doesn't show (and it doesn't in Preview) then here's the link: https://imgur.com/Xtc5M2z

Also -- a followup question? How to get an image to show in a post?

Thank you!

ThatJackElliott

Repel invaders! Nope, this version (5.15.3) of QjackCtl's Graph > View has no "Repel" anything. Thank you for the suggestion!

Hi LinuxMusicians and those who love them! I notice that every time I reboot the PC and load QjackCtl with a Patchbay definition, Graph is definitely a mess and I have to rearrange everything to make it pretty again. Is this expected behavior?

ThatJackElliott

Thank you, Robin Cherry. That won't work in my application, which is in a radio station's broadcast signal chain. If something on the PC gets its underpants in a tangle we can't have someone physically come in at, maybe 3 AM to unplug a cable and reboot. It's gotta come up and hit the ground running...
