| jkasha | Hi looking for help. :) My DAW was working great. After an Ubuntu update and reboot, qjackctl stopped seeing my USB-sound card (a Soundcraft MTK12). Going crazy to understand why. Doesn't appear in "readable" or "writable" clients in qjackctl Connections. But the USB sound device does appear when I do aplay -l. Ubuntu 19.10. Pulse routed into jack. Used to work great. Ideas? | 03:33 |
|---|---|---|
| tomreyn | jkasha: 19.10 is about to loose support anyways, i'd just upgrade to 20.04 and look into solving it there IF it's still an issue. | 08:29 |
| jkasha | thank you Tomreyn. I will try that. | 10:30 |
| tomreyn | you're welcome :) | 10:33 |
| jkasha | Tomreyn - I upgraded to Ubuntu 20.04, but I am still having same problem ... qjackctl does not list my USB soundcard (which is a Soundcraft MTK mixer/interface) in the readable/writable audio clients. It was working perfectly until yesterday. Upgrade to 20.04 seems not to have changed anything :( | 12:43 |
| jkasha | Any ideas, Tomreyn or anyone? Thank you! | 12:43 |
| jkasha | hi sending S.O.S. again in case anyone can help! My sound card (a USB-interface) stopped appearing in readable/writable clients in qjackctl. Seems to have happend after an unnounced kernel upgrade. I upgraded to Ubuntu 20.04 to see if it would help, but did not. Any ideas? Thank you!!! | 13:41 |
| jkasha | ... btw ... Linux recognizes the device is there. It is listed when I do "aplay -l" | 13:42 |
| jkasha | seems to be a jack or qjackctl or d-bus or jack dbus or something.... | 13:42 |
| tomreyn | jkasha: sorry, i missed your messages here | 16:25 |
| tomreyn | hmm, i'm afraid i won't be able to help there, i really have no clue about audio interfaces | 16:26 |
| tomreyn | nor about jack(d) really | 16:26 |
| tomreyn | if you can stay around for longer, i bet someone else will jump in. also see the /topic for more suggestion son how to find help | 16:27 |
| jkasha | thank you. appreciate your help so far. Hopefully someone else will come to my rescue! | 16:31 |
| jkasha | btw - a friend with a similar setup just told me he is also having similar problems. Is it possible something went wrong for many people? Anyone else having trouble reaching their usb-audio interface in qjackctl? not appearing as readable/writable client? | 17:33 |
| tomreyn | since you say you upgraded to 20.04, i assume this can be relevant: https://wiki.ubuntu.com/FocalFossa/ReleaseNotes/UbuntuStudio https://help.ubuntu.com/community/UbuntuStudio/UbuntuStudioControls | 18:18 |
| OvenWerks | jkasha: in a terminal (all one line): cd /tmp && wget https://community.ardour.org/files/adevices.sh && bash ./adevices.sh |pastebinit | 18:56 |
| jkasha | Overnwerks - just did. Thx for any help you can give! | 19:40 |
| jkasha | The device I want to use is the MTK. It has 14 ins/outs. It worked fine, until Fri. | 19:41 |
| OvenWerks | Wheres the URL that should have given? | 20:13 |
| jkasha | https://paste.ubuntu.com/p/XhNkVy69PX/ | 20:14 |
| OvenWerks | I am at a loss as to why qjackctl can't see that. Have you tried ubuntustudio-controls for running jack? | 20:17 |
| jkasha | Yes | 20:20 |
| OvenWerks | BTW we have found that a rm ~/.config/jack/conf.xml after having run qjackctl can be helpful | 20:20 |
| jkasha | thx. i just did rm etc. but still same. | 20:21 |
| jkasha | could it have smthg to do with dbus or jack d-bus? i get rather confused... | 20:22 |
| OvenWerks | in ubuntustudio-controls->audiosetup->jack master settings->USB device that should be Master ..... you can't find your device? | 20:23 |
| OvenWerks | -controls uses the same way for finding devices as the script you used to produce the URL above. | 20:23 |
| jkasha | I find the device in "USB device that should be Master", and I have it selected | 20:24 |
| OvenWerks | ok and then start jack button | 20:24 |
| OvenWerks | Then there is a button that says Carla | 20:25 |
| OvenWerks | when Carla opens, there is a tab called patchbay | 20:26 |
| OvenWerks | system:capture and playback shold be your USB device | 20:27 |
| jkasha | It only shows "system", which is only 2 channels, whereas my device (MTK) is 14ins/12outs (or vice versa). And I tried to see if that even corresponds to the first two inputs on my device ... it doesn't. | 20:28 |
| OvenWerks | ok what does the script above show now? | 20:28 |
| jkasha | When it used to work, in qjackctl, my device was listed as "system," but had all the inputs & outputs and worked. | 20:28 |
| OvenWerks | I understand | 20:28 |
| OvenWerks | I am trying to figure out what happened | 20:29 |
| jkasha | which script? sorry i'm confused. :) | 20:29 |
| jkasha | this? | 20:29 |
| jkasha | cd /tmp && wget https://community.ardour.org/files/adevices.sh && bash ./adevices.sh |pastebinit | 20:29 |
| OvenWerks | /tmp/adevices.sh |pastebinit | 20:29 |
| OvenWerks | Yeah | 20:29 |
| jkasha | https://paste.ubuntu.com/p/4c3rZw2SCG/ | 20:30 |
| OvenWerks | well it is your device for sure.... but why only two chanels | 20:30 |
| OvenWerks | Oh!, I see it. | 20:31 |
| OvenWerks | maybe not. | 20:31 |
| OvenWerks | 192000? | 20:31 |
| OvenWerks | why? | 20:31 |
| jkasha | it appeared difftly in the earlier version.... what changed | 20:32 |
| OvenWerks | anything above 48k is for bats | 20:32 |
| OvenWerks | jackdbus is now running | 20:32 |
| jkasha | that was there by default. maybe that was the problem? | 20:32 |
| jkasha | changing to 48k, which is what i always use. | 20:32 |
| OvenWerks | you will have to restart Carla after hitting the apply audio settings button | 20:33 |
| jkasha | do you recommend Carla over qjackctl? | 20:33 |
| OvenWerks | many devices change chanel count with SR | 20:34 |
| OvenWerks | personally I don't care :) but ubuntustudio policy is that Carla is the way forward | 20:34 |
| OvenWerks | and Caitia when that shows up | 20:34 |
| jkasha | Still not showing the channels. Will do that script again. And btw - (if you know) in qjackctl, there is a setting for frames/period just below SR (48k)... not sure what that is. It's set to 64, but not sure if that's good. | 20:35 |
| OvenWerks | I would stay away from using qjckctl to start jack, but the connections panel is still just fine | 20:35 |
| jkasha | https://paste.ubuntu.com/p/V88hzxz863/ | 20:36 |
| OvenWerks | 64 should be fine... | 20:36 |
| OvenWerks | That looks like you started it with qjckctl. | 20:38 |
| jkasha | yes | 20:39 |
| jkasha | i'll restart from pulse and do again. | 20:39 |
| OvenWerks | assuming so... under advanced in settings | 20:39 |
| OvenWerks | there is a "Channels I/O" | 20:39 |
| OvenWerks | is that set to 2 by chance? | 20:40 |
| jkasha | no it's on default | 20:40 |
| OvenWerks | Ah, yes if jack is stopped, | 20:40 |
| OvenWerks | pavucontrol may be able to set chanels | 20:41 |
| OvenWerks | pavucontrol->Configureation-><your device> drop down may show more than one chanel setup | 20:42 |
| jkasha | so should I set that while Jack is stopped in qjackctl? And if so, I presume I should set it to the correct number of ins/outs, right? | 20:42 |
| OvenWerks | yes | 20:42 |
| OvenWerks | if jack is running pavucontrol may not have access | 20:43 |
| jkasha | ok. i'll try in qjackctl, because I'm more familiar, unless you think it's important i use pavucontrol? | 20:43 |
| OvenWerks | you have to use pavucontrol I think | 20:43 |
| OvenWerks | Unless there is a switch/control right on your device that can change number of chanels | 20:44 |
| jkasha | you're not gonna believe this... i just changed the usb cable and it's working. it's the one i was using all along. when it stopped worked, i put in a newer longer one. i just put the older, short one back, and boom! my 14/12 channels are back. | 20:47 |
| OvenWerks | \o/ | 20:47 |
| OvenWerks | good | 20:47 |
| jkasha | i'll do some tests to see if it actually works. sorry to have taken up so much of your time. much appreciate your help. i'll let you know after I test. | 20:48 |
| OvenWerks | If you are used to qjackctl feel free to keep using it | 20:48 |
| OvenWerks | on the advanced page I would change the "Port Maximum" to 1024 | 20:49 |
| OvenWerks | (default is 2048 but qjackctl doesn't seem to allow that) | 20:49 |
| OvenWerks | I think that is it for the advanced page | 20:49 |
| OvenWerks | In general the default settings are good | 20:50 |
| jkasha | https://www.youtube.com/watch?v=3GwjfUFyY6M | 20:51 |
| jkasha | Thank you so much!!! | 20:51 |
| OvenWerks | you're welcome | 20:51 |
| jkasha | i'm getting weird behavior nonetheless. :( i'm going to reboot and see if that helps. | 21:01 |
| jkasha | Youtube doesn't play correctly now. for whatever reason, it was working before i did the Port Max change. now it doesn't work, even when i set it back. | 21:07 |
| jkasha | or i should say, youtube won't play media. the MTK device is there and the channels are correct. | 21:07 |
| jkasha | Ovenwerks ... now i can't even start jack... :( I get an error that says "D-BUS: Jack server could not be started." | 21:19 |
| jkasha | my head is looping! | 21:19 |
