| kdenliver | Hey! This may be question asked in a kdenlive forum or something, but do I have to install some ffmpeg on Ubuntu to make the proxy clips? | 06:38 |
|---|---|---|
| kdenliver | Never mind, I think it's already installed. Thanks, I just got the path. | 06:46 |
| cupantae | Hey :) I'm trying out Ubuntu Studio for the first time and it looks really slick, but..... | 17:04 |
| cupantae | Jack does not work. Which is unfortunate because avoiding understanding Jack was the main reason I installed | 17:04 |
| cupantae | Didn't check it from the live system. Any ideas? | 17:05 |
| OvenWerks | Jack should just work | 17:06 |
| OvenWerks | how does jack fail for you? cupantae | 17:06 |
| OvenWerks | cupantae: how are you running jack? | 17:07 |
| cupantae | Will I show you some Qjackctl output? | 17:07 |
| OvenWerks | Why are you using qjackctl instead of ubuntustudi0o-controls? | 17:07 |
| OvenWerks | but sure | 17:07 |
| cupantae | I've also tried Start/Restart Jack in Ubuntu Studio Controls but that does nothing and gives no output | 17:07 |
| cupantae | that I can see | 17:07 |
| cupantae | I can try running that from a terminal? | 17:08 |
| OvenWerks | sure | 17:08 |
| StevenJayCohen | An output log would be a welcome addition to Studio Controls | 17:08 |
| OvenWerks | there is one | 17:08 |
| StevenJayCohen | ? | 17:08 |
| StevenJayCohen | checking... | 17:08 |
| cupantae | Cannot connect to server socket err = No such file or directory...is the first thing that comes out. It spams the same few lines over and over while USC is running | 17:09 |
| OvenWerks | generally ~/.log/autojack,log | 17:09 |
| cupantae | JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock | 17:09 |
| cupantae | is also possibly significant | 17:09 |
| StevenJayCohen | OvenWerks, ahh, with newbies in mind I was hoping for a button in Studio Controls to open the log | 17:09 |
| cupantae | OvenWerks: I don't have that file but I have .log/jack/jackdbus.log | 17:10 |
| OvenWerks | StevenJayCohen: with the new (20.04) version there is also a debug level | 17:10 |
| StevenJayCohen | OvenWerks, nice! | 17:10 |
| cupantae | ERROR: failed to stat "/home/ubustudio/.config/jack/conf.xml", error is 2 (No such file or directory) | 17:11 |
| cupantae | is the first error there | 17:11 |
| OvenWerks | cupantae: perhaps a screen shot of the audio tab of -controls might help | 17:11 |
| cupantae | ok | 17:11 |
| OvenWerks | That error should not be a problem. | 17:11 |
| cupantae | OK | 17:12 |
| cupantae | https://imgur.com/qNCE80R.png | 17:12 |
| cupantae | That "host on imgur" option in the PrntScr window is a very nice feature. | 17:13 |
| cupantae | (I guess that's an Xfce feature) | 17:13 |
| cupantae | Here's another bit from the .log/jack/jackdbus.log | 17:15 |
| cupantae | ERROR: ALSA: Cannot open PCM device alsa_pcm for playback. Falling back to capture-only mode | 17:15 |
| cupantae | So it could be a sound card / alsa issue? | 17:15 |
| OvenWerks | give me a sec, on the phone | 17:16 |
| cupantae | Yeah, no rush at all lol | 17:16 |
| OvenWerks | cupantae: it sounds like your default device is HDMI from your video? | 17:17 |
| OvenWerks | cupantae: in a terminal type this all as one line: cd /tmp && wget https://community.ardour.org/files/adevices.sh && bash ./adevices.sh |pastebinit | 17:18 |
| OvenWerks | then give us the url that should result | 17:19 |
| OvenWerks | (BTW there is a newer version of -controls) | 17:19 |
| Eickmeyer | Newer version of -controls is in Backports for Eoan and Bionic. | 17:24 |
| Eickmeyer | !ubuntustudio-backports | 17:24 |
| ubottu | The Ubuntu Studio Backports PPA is required for users of Ubuntu Studio to receive LTS support for Ubuntu Studio 18.04, and for #ubuntustudio to support users of Ubuntu 18.04 LTS and its flavors using !jack. For more info, see https://help.ubuntu.com/community/UbuntuStudio/BackportsPPA, !ubuntustudio-controls, and !ubuntustudio-installer | 17:24 |
| cupantae | OvenWerks: will try and report back hopefully soon | 17:27 |
| cupantae | Eickmeyer: I'll take a look at that too | 17:28 |
| Eickmeyer | cupantae: Also, just to note: your screenshot showed you hadn't set an audio device. "default" doesn't always work, it's best to just specify when stuff isn't working. | 17:28 |
| cupantae | Eickmeyer: OK let's start with that | 17:29 |
| cupantae | Yeah I think this might be the issue. There are 4 HDMI devices showing and another.. I am not using HDMI | 17:30 |
| cupantae | Oh! Pavucontrol shows no devices at all | 17:32 |
| OvenWerks | That is correct | 17:32 |
| cupantae | OK | 17:33 |
| cupantae | It seems like it's running now :) | 17:33 |
| OvenWerks | pavucontrol should just show jacksink/source | 17:33 |
| cupantae | I just selected the non- | 17:33 |
| cupantae | whoops | 17:33 |
| cupantae | pavucontrol shows just dummy output | 17:33 |
| cupantae | Oh no, now that jack is working, you're right | 17:34 |
| Eickmeyer | That means pulseaudio isn't running/there are no jack bridges. | 17:34 |
| cupantae | I see | 17:34 |
| OvenWerks | I think it was just jack was not there yet | 17:34 |
| cupantae | I just selected the non-HDMI card before hitting Start/Restart in USC. | 17:34 |
| OvenWerks | cupantae: right | 17:34 |
| cupantae | It's called "PCH,0,0 playback and capture (ALC255 Analog)" | 17:35 |
| OvenWerks | PCH maybe | 17:35 |
| cupantae | Well done :) I suppose that's my laptop speakers? | 17:35 |
| OvenWerks | PCH is generally what on board audio is called | 17:35 |
| cupantae | Cool beans | 17:36 |
| cupantae | This is great anyway! Thank you both OvenWerks and Eickmeyer. No need to edit config files or anything =D | 17:36 |
| Eickmeyer | Yep. It just works. (tm) | 17:37 |
| OvenWerks | It used to be almost always what showed as default, but many newer systems put hdmi first | 17:37 |
| cupantae | It's certainly working. Now I just have to teach myself how to use these programs XD | 17:51 |
| OvenWerks | cupantae: the main thing to remember with jack is that not all programs auto connect to the audio device. Use patchage or Carla to check or make new connections | 18:00 |
| Turdlar | regarding carla and patchage - i keep seeing them recommended for hooking things up with eachother. what are the differences from them to qjackctl and aconnectgui? | 18:04 |
| Turdlar | im asking because qjackctl has gotten me through most everything i wanted to achieve | 18:08 |
| OvenWerks | Turdlar: those are both fine too. | 18:08 |
| Turdlar | and the interface is way less scary in comparison to carla and patchage | 18:09 |
| OvenWerks | We try to avoid recommending qjackctl because using it to start jack gives problems for people using USB mics | 18:09 |
| OvenWerks | that is two devices at the same time | 18:09 |
| Turdlar | haha, ouch! that explains the first 10 hours of troubleshooting i did in ubuntu studio | 18:10 |
| OvenWerks | With qjackctl there are some many paramters the chance of making it so nothing works is easy | 18:11 |
| Turdlar | i got around it by disabling all other sound inpit or output sources on a bios level | 18:11 |
| Eickmeyer | !ubuntustudio-controls | 18:12 |
| ubottu | Ubuntu Studio Controls is the application through which audio is configured in Ubuntu Studio. It configures Jack, sets the CPU governor, and ensures the user has realtime audio permissions. For more info, see !jack and https://help.ubuntu.com/community/UbuntuStudio/UbuntuStudioControls | 18:12 |
| Eickmeyer | And think of Carla's patchbay as exaclty that: connecting wires between devices. It's that simple. | 18:12 |
| Turdlar | but why is qjackctl included then? if it creates known issues with common hardware, then i figure it would be easier to leave it out? | 18:13 |
| Eickmeyer | Turdlar: Because it's part of the Jack package and we can't exclude it. | 18:13 |
| Turdlar | ah. ok | 18:13 |
| OvenWerks | And some people just don't want to change :) | 18:14 |
| Eickmeyer | ^ | 18:14 |
| Turdlar | it seems like Patchage is showing more options for me to connect, compared to Carla | 18:14 |
| Turdlar | looking forward to play around with it | 18:14 |
| Eickmeyer | If that works for you, then go for it. | 18:14 |
| Eickmeyer | New carla version will be dropping soon for 20.04, but for reasons can't be backported. | 18:15 |
