| Kraus | Where does Ubuntu Studio Controls store its presets and configurations? | 03:37 |
|---|---|---|
| Kraus | Hm. Seems a question similar to mine was asked on Launchpad in May with no response. https://answers.launchpad.net/ubuntustudio-controls/+question/690409 | 04:32 |
| OvenWerks | Kraus: presets or config? anyway, ~/.config/autojack/autojackrc | 05:20 |
| Kraus | OvenWerks: Oooh! Okay, let's see.. | 05:32 |
| OvenWerks | if your version is old enough it will be ~/.config/autojackrc | 05:34 |
| OvenWerks | latest version is 2.0.7 | 05:34 |
| Kraus | Okay, I found the file. It has the ' pulse-in = ' and ' pulse-out = ' but doesn't have any of the channels=2 or channel_name= info. | 05:34 |
| Kraus | What I'm trying to do is find out how to change the output bridge configurations. | 05:35 |
| OvenWerks | no we do not yet have a setting for number of channels | 05:35 |
| OvenWerks | but changing the name has been possible for a while | 05:35 |
| Kraus | https://askubuntu.com/questions/1274267/ubuntu-studio-controls-how-to-add-and-map-surround-audio-channels-to-a-pulse-ou | 05:36 |
| Kraus | That's where I posted the original question if it helps understand what I'm trying to do. | 05:36 |
| OvenWerks | the title is pretty clear :) | 05:36 |
| Kraus | Yeah, whenever I create a module manually, USC overrides my work when I restart Jack. | 05:37 |
| Kraus | pacmd load-module module-jack-sink sink_name=Surround client_name=Surround channels=4 connect=no | 05:37 |
| Kraus | Is there any way I can tell USC to not do that? | 05:37 |
| OvenWerks | two ways: hack ubuntustudio-controls, run a script after controls starts | 05:37 |
| OvenWerks | The file to change would be /usr/bin/autojack | 05:38 |
| Kraus | This poor guy asked about this same question back in May: https://answers.launchpad.net/ubuntustudio-controls/+question/690409 | 05:38 |
| Kraus | Wish I could code. I'd help add that functionality to USC. Seems super important. | 05:39 |
| Kraus | I'm picturing an output bridge editor dialog box where the user could set the attributes either manually in a text field or a series of drop-downs. | 05:41 |
| OvenWerks | the file is script and the change for what you want would be one or two lines | 05:41 |
| OvenWerks | but it would not be changable. | 05:41 |
| OvenWerks | The problem is that autojack has changed a lot since your version and so if I give a line number that would not help | 05:42 |
| OvenWerks | search might work though | 05:42 |
| Kraus | Sorry, I don't understand. | 05:42 |
| Kraus | Hmmm... I typed $autojack --help and now I'm hearing a bunch of crackling in my earphones. | 05:43 |
| Kraus | I'll let the guys in the Linux Audio discord I'm part of know there's no way to change the channel number yet. | 05:44 |
| OvenWerks | --help would not help | 05:44 |
| Kraus | I was just trying to find a little more information about what autojack is. | 05:44 |
| OvenWerks | you would need to edit that file | 05:44 |
| OvenWerks | autojack is a daemon that runs in the background and accepts commands from studio-controls as well as monitors hardware for new usb devices getting (un)plugged | 05:46 |
| OvenWerks | it then adjusts how jack runs | 05:46 |
| Kraus | Ahh, is it part of ubuntustudio-control or is it something else entirely? | 05:46 |
| Kraus | I mean is it part of the same project? | 05:46 |
| OvenWerks | they are all a part of the same package | 05:47 |
| Kraus | Okay. So, I can edit the file, but then I'm confused because you said it would not be changable? | 05:47 |
| OvenWerks | it started as a personal script and then as a way for a more painless use of USB microphones which are never "profesional" :) | 05:48 |
| Kraus | Here here. Yeah, I'm using an audio interface now. | 05:48 |
| Kraus | I see the line: | 05:49 |
| Kraus | cp = subprocess.run(["/usr/bin/pactl", "load-module", "module-jack-sink", f"client_name={poname}", "channels=2", "connect=no"], etc etc. | 05:49 |
| OvenWerks | you can edit it, but once you change the number of chanels for a pulse-jack bridge it will stay at that number so if you change it to 6 channel then it will stay that way untill you edit it again | 05:49 |
| Kraus | Right, seems reasonable | 05:49 |
| OvenWerks | yes you can change the channels= to 4 | 05:49 |
| OvenWerks | you will probably find there is more than one line like that | 05:50 |
| OvenWerks | There are two of them | 05:50 |
| OvenWerks | one for startup and one for recongifuring | 05:51 |
| Kraus | Interesting | 05:51 |
| OvenWerks | reconfiguring even | 05:51 |
| Kraus | Alright, here goes.. no guts, no glory... | 05:52 |
| OvenWerks | you will need to use sudo nano /usr/bin/autojack | 05:53 |
| Kraus | Right. | 05:53 |
| Kraus | Well this does explain a lot. :) | 05:54 |
| OvenWerks | I will add channel number to my list of feature requests... | 05:55 |
| Kraus | I do wonder what this will do to that drop-down with the channel list. I have a feeling it's going to break it. | 05:55 |
| OvenWerks | only the first two channels will auto connect | 05:56 |
| Kraus | channels= and channel_map= since they kind of work together. | 05:56 |
| Kraus | Depending on if it's 4.0 surround, 5.0, 5.1, 7.1, etc. the channels map differently. | 05:56 |
| Kraus | I recently peeked at the jack manual page for modules. | 05:57 |
| OvenWerks | I don't think the pulse-sink module really goes farther than number | 05:57 |
| Kraus | https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/ | 05:57 |
| OvenWerks | (I could be wrong) | 05:57 |
| Kraus | "channel_map ... Channel map. A list of comma-separated channel names. The currently defined channel names are: left, right, mono, center, front-left, front-right, front-center, rear-center, rear-left, rear-right, lfe, subwoofer, front-left-of-center, front-right-of-center, side-left, side-right, aux0, aux1 to aux15, top-center, top-front-left, top-front-right, top-front-center, top-rear-left, top-rear-right, top-rear-center, | 05:58 |
| Kraus | (Default depends on the number of channels and the driver) | 05:58 |
| Kraus | " | 05:58 |
| OvenWerks | ah channelmap is there | 05:59 |
| Kraus | These USB audio interfaces have many different channels mappable. Mine has 10 analog monitor outputs, each with a 1/4" TRS jack. There is someone on linuxmusicians.com currently making drivers for the entire line made by Focusrite Scarlett's 3rd gen interfaces. | 05:59 |
| Kraus | So, to use that, I need a pulse sink that has the channels mapped so I can connect them through Carla. :) | 06:00 |
| Kraus | That's why USC is so important to have this, because otherwise all of these professional musicians can't use USC. | 06:00 |
| OvenWerks | It seemed to me the default was pretty reasonable | 06:01 |
| Kraus | :) | 06:01 |
| OvenWerks | two channels is pretty standard | 06:01 |
| Kraus | If I showed you what my Carla looks like you'd freak out, hehe | 06:01 |
| OvenWerks | no probably not. | 06:02 |
| OvenWerks | but people selling music generally do so in stereo if for no other reason than most media deals with that well. | 06:02 |
| OvenWerks | if it is stereo of spotify or bandcamp or whtever. | 06:03 |
| Kraus | Dolby Surround 5.1, etc. People have surround sound monitor setups for when editing films and videos. | 06:03 |
| OvenWerks | videos with action are the biggest place for surround | 06:03 |
| Kraus | VLC for playing movies, etc. | 06:03 |
| Kraus | Yeah | 06:04 |
| Kraus | Okay, I edited the python file.. so if I restart jack in USC hopefully it will work? | 06:05 |
| OvenWerks | anyway, as I said, I can add channels other than two in newer versions... probably for 21.04 | 06:05 |
| OvenWerks | no you need to killall autojack first | 06:05 |
| OvenWerks | Then restarting jack will restart autojack | 06:06 |
| Kraus | Oh, okay.. oh well, it looks like it worked regardless, hehe. | 06:06 |
| OvenWerks | good | 06:06 |
| Kraus | Hmmmmm... confusion arises... | 06:09 |
| Kraus | autojack, does it know about my additional bridges? | 06:09 |
| Kraus | I have a bridge called pulse_out and discord_out | 06:10 |
| OvenWerks | did you add another bridge or change the number of channels | 06:10 |
| Kraus | I'll need to explain | 06:10 |
| OvenWerks | It depends of the version of controls. later versions allow a number of bridges | 06:10 |
| OvenWerks | but in general if controls did not start it then controls doesn't know about it. | 06:10 |
| Kraus | Because I could not add a 4-channel bridge in USC, I removed pulse_out, but kept discord_out. I would use pacmd to manually make the 4-channel bridge. When I changed the python file I forgot to remake pulse_out in USC, so it made the discord_out 4 channels. It added the channels just fine. But, now that I can change the python script I am going to remake pulse_out. But I just noticed the python script doesn't have "discord_out | 06:12 |
| Kraus | " anywhere in it. | 06:12 |
| OvenWerks | if you had the newer version of controls, it could have more than one bridge | 06:13 |
| Kraus | I do? | 06:13 |
| OvenWerks | you should have ubuntustudio-installer | 06:13 |
| Kraus | I mean, how do I find out the version I have. | 06:14 |
| Kraus | I mean, how do I find out the version I have? | 06:14 |
| Kraus | I installed ubuntu studio 20.04 | 06:14 |
| OvenWerks | if you use that to enable the backports ppa then the newer version should auto install next update | 06:14 |
| Kraus | Waitwait | 06:14 |
| Kraus | How do you know I don't have the newer version of controls? | 06:14 |
| OvenWerks | for 20.10 it is now called studio-controls | 06:14 |
| Kraus | Oh, 20.10 got released? | 06:15 |
| OvenWerks | no but the backports ppa hasit | 06:15 |
| Kraus | Ahhh. | 06:15 |
| Kraus | It is possible to make more than one bridge with my version, though. | 06:15 |
| OvenWerks | I have to go now | 06:15 |
| Kraus | Ok | 06:15 |
| OvenWerks | wife is calling | 06:16 |
| Kraus | Hehe | 06:16 |
| Kraus | OvenWerks: For when you come back: It looks like editing the python script to 4 channels changes ALL output bridges to 4 channels. | 06:22 |
| Kraus | I don't think this will have any significant effect in my situation because discord is only monophonic anyway. | 06:24 |

| jkasha | Hope someone can help me please with the following error: "The disk system on your computer | 20:36 |
| jkasha | was not able to keep up with Ardour. Specifically, it failed to write data to disk quickly enough to keep up with recording." I get this error when I'm recording only a single track, usually 20-30 seconds into it. I’m at 48khz and 32bit floating. I don't always get this error, but usually I do. Using Ubuntu Studio 20.04 [uname -r reports: 5.4.0-47-lowlatency]. I never used to have this problem, using exact same ha | 20:36 |
| jkasha | rdware, both in Fedora previously and more recently in Ubuntu. I have run disk utility and the disk is fine, and it is mounted properly. Any ideas? I can’t figure it out on my own. Thank you. J | 20:36 |
| Eickmeyer[m] | jkasha: Usually means either your disk is too slow, the hardware is too slow to write to the disk (sometimes SATA I isn't even enough), but really sounds like a hardware problem 100% on your end, might be due to the different version of the kernel. That's a loaded question, to which there is really no cut-and-dry answer. I suggest troubleshooting or asking the folks in #ardour, #lau (Linux Audio Users) or #opensourcemusicians if | 21:00 |
| Eickmeyer[m] | they've had any issues like this (hint: most haven't). | 21:00 |
| jkasha | Thx Eickmeyer. Will sound out some of those other channels. :( | 21:07 |
| OvenWerks | Kraus: yes, that would be the result. When I work on this next it will be able to choose different numbers of channels per bridge, but because you have a need for it now and not some months away... a quick hack will work. | 21:13 |
