| StevenJayCohen | What device do you have set as default in Ubuntu Studio Control | 10:08 |
| Luca | one sec that it asks me to update my system | 10:11 |
| Luca | StevenJayCohen: I cannot open the Ubuntu Studio Control | 10:45 |
| Luca | And I got a crash: https://imgur.com/ucmqqiV.png | 10:48 |
| StevenJayCohen | Can you launch it after an update and a reboot? I had issues with it that were solved by an update | 11:03 |
| StevenJayCohen | Sorry for the slow reply, making coffee | 11:03 |
| Luca | StevenJayCohen: Updated and Rebooted, but still the same | 11:08 |
| StevenJayCohen | How about qJackCtl? | 11:08 |
| Luca | For reference about the crash: https://imgur.com/Eyo4Jtm.png | 11:10 |
| Luca | Ok, I am having multiple problems with QJackCtl, and I absolutely need to find a way to have it working. Definitely problems with this laptop of mine, but this is what I have got right now | 11:11 |
| Luca | When I try to start QJackCtl I get the following error: Sat Apr 18 13:11:15 2020: Starting jack server...Sat Apr 18 13:11:15 2020: JACK server starting in realtime mode with priority 10Sat Apr 18 13:11:15 2020: self-connect-mode is "Don't restrict self connect requests"Sat Apr 18 13:11:15 2020: Acquired audio card Audio0Sat Apr 18 13:11:15 2020: | 11:12 |

| Luca | settings to "/home/luca/.config/jack/conf.xml" ... | 11:12 |
| Luca | Basically, I noticed that I have this problem with more or less all kernels after 5.3.0-18 (QJackCtl started with Ubuntu Studio 19.10) | 11:13 |
| StevenJayCohen | What's your audio hardware? | 11:16 |
| Luca | StevenJayCohen: the lspci command says "Multimedia audio controller: Intel Corporation Device 02c8" | 11:20 |
| StevenJayCohen | Does this happen in a new user as well (without your settings, a brand new account)? | 11:26 |
| Luca | Well, this is a out-of-the-box installation | 11:31 |
| StevenJayCohen | <Luca "Well, this is a out-of-the-box i"> It takes 3 minutes for you to confirm | 11:32 |
| Luca | I bought a computer exactly like this one (Lenovo C640) in December, installed Ubuntu 19.10 and had Jack working. After, the computer broken, I bought another one of the same type, and now I have problems with more or less all OS | 11:33 |
| Luca | StevenJayCohen: how can I try to make a brand new account? | 11:33 |
| StevenJayCohen | Add a user and log into that user | 11:34 |
| Luca | StevenJayCohen: Ok, just tried to switch account to a brand-new one and I have the same problem with jack | 11:37 |
| StevenJayCohen | Your audio hardware? What is it? | 11:38 |
| Luca | StevenJayCohen: I cannot retrieve the model as the command "aplay -l" doesn't show any sound device: https://imgur.com/oPeFimw.png | 11:50 |
| Luca | It's a Realtek Alc+something | 11:51 |
| Luca | Maybe an Alc882, but I am not sure | 11:53 |
| Luca | Wait, I go to windows and check | 11:58 |
| StevenJayCohen | Have you filed a bug on this? | 11:59 |
| Luca | StevenJayCohen: sorry, I am unable to retrieve the specific Realtek sound card type | 12:08 |
| Luca | However, this is the model: https://www.lenovo.com/gb/en/laptops/yoga/yoga-c-series/Yoga-C640/p/88YGC601300 | 12:10 |
| oerheks | lspci should tell. | 12:26 |
| oerheks | adding: set-card-profile 0 HiFi to /etc/pulse/default.pa seems to solve it. | 12:27 |
| oerheks | https://forum.manjaro.org/t/lenovo-yoga-c640-sound/126933/2 | 12:27 |
| oerheks | interesting that you shared the specs only now. | 12:28 |
| Luca | oerheks: lspci says "Multimedia audio controller: Intel Corporation Device 02c8" | 12:28 |
| oerheks | no, it should say xxxx:yyyy as number | 12:28 |
| Luca | I don't know. Here is the log of the command: https://imgur.com/v6zdsxR.png | 12:30 |
| oerheks | odd... | 12:31 |
| Luca | There are very many odd things with this machine of mine. I just don't understand if there is some serious hardware problem specifically on this machine | 12:32 |
| oerheks | see if that manjaro fix works for you | 12:32 |
| Luca | Yep, I reboot now and see | 12:33 |
| Luca | thanks for now | 12:33 |
| Luca | The fix didn't resolve the problem | 12:35 |
| Luca | Should I try to downgrade my kernel to the one that was working (UbuntuStudio 19.10 - 5.3.0-18), so to see if it still works with that kernel? | 12:36 |
| oerheks | there is no downgrade possible. | 12:42 |
| oerheks | you are on 20.04? | 12:42 |
| Luca | yes 20.04 | 12:43 |
| StevenJayCohen | And 19.10 works? | 12:44 |
| Luca | And 19.10 worked in this respect (although there was another kind of problem) | 12:45 |
| Luca | oerheks: can I not just download the kernel and install it? | 12:45 |
| StevenJayCohen | Then you could refer to 19.10 report the issue and wait for the .1 update | 12:45 |
| Luca | StevenJayCohen: sorry, I did not understand what you mean | 12:46 |
| StevenJayCohen | What's more important a working machine or making the newest version work today? | 12:46 |
| Luca | in 19.10, it worked everything perfectly, apart that there was no sound coming our of my computer at all. OvenWerks and I tried to go through this problem, but it was like a magical problem: everything seemed to work just fine, but still no sound | 12:47 |
| StevenJayCohen | And if you change out the interface for another one? | 12:48 |
| Luca | A working machine. But it is not working properly in Ubuntu 18.04, 19.10, Ubuntu Studio 19.10 nor 20.04 :) | 12:48 |
| Luca | StevenJayCohen What do you mean by changing interface? | 12:48 |
| StevenJayCohen | The device that Jack is using to talk to your mic and instruments | 12:49 |
| Luca | Either Ubuntu 18.04 and 19.10, if I remember correctly, had both sound and Jack working, although I kept having a choppy sound ot of Jack | 12:49 |
| Luca | StevenJayCohen: well, I have none right now. | 12:50 |
| StevenJayCohen | And before you installed you tested by running it from the USB live and had no issues? | 12:50 |
| Luca | StevenJayCohen: I can't answer that, as I didn't try actually. But I can now if you want | 12:51 |
| StevenJayCohen | No just wondering how the system broke and what the original working state was | 12:53 |
| Luca | Well, I have problems with jack with more or less all kernels after 5.3.0-something. It's really a recurrent problems among different OS. | 12:54 |
| oerheks | long bugreport, no fix.. that 02c8 device is not supported.. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439 | 12:55 |
| Luca | And before 5.3.0-something, I have a Choppy Jack sound | 12:55 |
| ubottu | Launchpad bug 1850439 in linux (Ubuntu) "No sound on ASUS UX534FT" [Undecided,Confirmed] | 12:55 |
| oerheks | i wonder why you have choppy sound, nobody got it working | 12:56 |
| Luca | weird enough, 5 months ago, when I bought this machine for the first time, everything just worked fine. That's very incredible | 12:56 |
| StevenJayCohen | So some piece of hardware you own has issues with all newer software. I don't think we're going to be able to fix it here if it's always broken | 12:57 |
| StevenJayCohen | I would say revert back to that original os | 12:57 |
| Luca | oerheks , I was able to have it working multiple times hacking here and there (of course, randomly hacking as I don't really understand what I write), Just kept being choppy | 12:57 |
| StevenJayCohen | Go back to the last stable state | 12:57 |
| Luca | StevenJayCohen: "that original os", I really wished I knew which one was | 12:58 |
| Luca | I asked online how to retrieve information on old versions. That time I installed Ubuntu 19.10 from the official website. Now, the release from that same website doesn't work | 12:59 |
| Luca | It looks more that that time I was just lucky | 12:59 |
| Luca | @oer | 13:00 |
| Luca | oerheks: thank you for having searched for the bug! | 13:00 |
| StevenJayCohen | On any Ubuntu mirror, you can grab an old is with an older kernel. Test it via USB key before install. Find a good state. Install that. Use Clonezilla to make a backup. Then upgrade. If it breaks restore from Clonezilla. | 13:08 |
| StevenJayCohen | Old OS* | 13:08 |
| Luca | StevenJayCohen, oerheks: Guys, I know that this makes no sense, but I just booted with kernel 5.3.0-18-lowlatency and now it works | 13:10 |
| Luca | Event the Ubuntu Studio Controls | 13:10 |
| Luca | https://imgur.com/PgWswHL.png | 13:11 |
| StevenJayCohen | Make a fresh backup now | 13:12 |
| Luca | I have now other problems :D | 13:12 |
| Luca | "Establishing connection to PulseAudio. Pease wait..." | 13:13 |
| StevenJayCohen | Ubuntu Studio Controls should do that for you | 13:20 |
| Luca | Guys! We are proceeding very well!! I have sound a Jack working | 13:23 |
| Luca | StevenJayCohen: how can I make a backup now? | 13:24 |
| StevenJayCohen | Install deja dupe from the app store | 13:25 |
| StevenJayCohen | Once installed, it will be needed backup | 13:25 |
| StevenJayCohen | Named* | 13:25 |
| Luca | Super good thanks. I do that now | 13:26 |
| Luca | Now I have a choppy sound. Somebody wanna try to solve that with me? This is the last step from having a completely working machine and being happy | 13:29 |
| StevenJayCohen | My guess, somehow you have started multiple Jack sessions so the same time | 13:38 |
| StevenJayCohen | Drop all Jack sessions in qJackCtl | 13:39 |
| StevenJayCohen | Check in Ubuntu Studio Control to be sure it is stopped there too | 13:39 |
| StevenJayCohen | Then reboot | 13:39 |
| StevenJayCohen | Then ONLY start Jack from Ubuntu Studio Control | 13:40 |
| Luca | StevenJayCohen: to drop all Jack sessions I just press the "Stop" button, or should I also do something else? | 14:22 |
| OvenWerks | Luca: not getting sound and jack complaining about 1024 being to low sounds like audio is going to hdmi or that your system sound is hard tied to hdmi | 14:23 |
| OvenWerks | try setting jack to 4096 buffer size and see if jack runs | 14:24 |
| Luca | OvenWerks: hi! Now Jack runs fine and I can hear sound from both pulsaudio and jack. My last problem is that Jack makes sound choppy | 14:25 |
| OvenWerks | good | 14:27 |
| StevenJayCohen | Luca: follow OvenWerks request, set Jack to 4096 | 14:28 |
| Luca | At this point, however, I would consider the option that my system is hard tied to hdmi (whatever this means). Is there a way to understand it? | 14:28 |
| OvenWerks | opps hes gone. | 14:31 |
| OvenWerks | Luca: looking at the way your devices are layed out, all of your internal devices including hdmi are listed as card 0 | 14:32 |
| Luca | OvenWerks, StevenJayCohen: Much progress I suppose. I followed both suggestions, rebooted and set 4096 | 14:32 |
| Luca | I pressed "Start or Restart Jack" from the Controls | 14:33 |
| StevenJayCohen | Still choppy? | 14:33 |
| Luca | I opened youtube, and played a video. It works fine | 14:33 |
| Luca | Dows it mean it is working? | 14:33 |
| OvenWerks | it means it is working at a large buffer | 14:33 |
| OvenWerks | That may be ok for most thing | 14:34 |
| Luca | How can we prove it? Meaning -> what is a Jack-dependent audio software here that I can see if it works? | 14:34 |
| StevenJayCohen | You can set Jack lower one step at a time and restart the jack server until you hear choppiness. When you hear choppiness, go back up one setting. | 14:34 |
| StevenJayCohen | Wait, what audio software do you use that requires JACK? | 14:35 |
| OvenWerks | but (from reading the back scroll) if this hardware is known for similar problems. It sounds to me like they have tied the hdmi sync together with the onboard sync | 14:36 |
| Luca | Usually SuperCollider. That will be my final proof :D | 14:36 |
| OvenWerks | and hdmi generally askes for 4096 | 14:36 |
| OvenWerks | there are some very cheap audio devices that will work better. | 14:36 |
| Luca | OvenWerks, I don't understand what that means, but anyway you're guess worked | 14:36 |
| StevenJayCohen | Luca: You may want some SuperCollider specific support at this point. You can find them at this link: https://join.slack.com/t/scsynth/shared_invite/enQtMzk3OTY3MzE0MTAyLTFmMTliMmU0NjIwYzgyZGY1MjgxNGI2MGUxMTNlMWVhZWQzZjFmOTJhNzg2NDdmNzZmM2JiYTkyMjRiNDBiOTk | 14:38 |
| StevenJayCohen | That's a supercollider Slack channel | 14:39 |
| Luca | Ok, I tried that with Blender and it worked! Technically Blender is Jack-depending. So super thank you everybody!! | 14:39 |
| Luca | StevenJayCohen: that's very useful, thank you | 14:39 |
| Luca | Thank you everybody for your time and patience | 14:39 |
| StevenJayCohen | Be well Luca, stay safe! | 14:39 |
| Luca | I'll have to write all this down somewhere for people in the future looking why their Lenovo c640 isn't working | 14:40 |
| OvenWerks | https://www.amazon.ca/Adapter-CableCreation-External-Microphone-Compatible/dp/B0776QNHKD/ref=sr_1_17?crid=MFDFYK32ZBKS&keywords=usb+audio+adaptor&qid=1587220762&sprefix=usb+audio%2Caps%2C293&sr=8-17 | 14:40 |
| Luca | StevenJayCohen: Yes, you too! | 14:40 |
| StevenJayCohen | OvenWerks: I missed that all of the devices were at 0 on that one | 14:40 |
| OvenWerks | is an example of something thatwill work at least down to 64 sample buffer | 14:40 |
| OvenWerks | I have found them for as low as 10 cents | 14:41 |
| OvenWerks | (and cost $5 to ship :P) | 14:41 |
| StevenJayCohen | I've gotten spoiled with my Audient Interface, can do 32 without xruns | 14:41 |
| OvenWerks | but they all look to be around $10 any more | 14:44 |
| OvenWerks | StevenJayCohen: even though they are all on card 0, they should be able to operate incependantly | 14:45 |
| OvenWerks | I would say on this hardware they have chosen to use one clock for all | 14:46 |
| OvenWerks | I have seen stuff like this before or the oposite way. I had a laptop where the bult in mic was 48k only. but the audio i/o jack could be 44k1 as well and the hardware allowed for setting the SR there. | 14:47 |
| OvenWerks | If the SR was set to 44k1 everything worked but the mic had a static-y sound. Set the SR to 48k and it was fine. | 14:48 |
| Luca | OvenWerks, StevenJayCohen: Just wanted to report that now everything is working even a 1024. Can't understand why, but it works great. Thanks | 15:11 |
| StevenJayCohen | great | 15:19 |
| shaban238 | OvenWerks hi! if i setup 256 buffer size in ubuntustudiocontrol and than hit apply auio settings, when i open qjackctl preferences i notice that the buffersize there its still 1024. within the DAW anyway its 256. i mean, it looks normal but should it visually change it also in qjackctl? | 20:20 |
| OvenWerks | it depends on where you look in qjackctl | 20:26 |
| shaban238 | qjackctl/srtup/parameters | 20:27 |
| shaban238 | setup* | 20:27 |
| OvenWerks | in the messages status window in the status tab you should see the real numbers | 20:27 |
| OvenWerks | setup is just what qjackctl will use the next time it starts | 20:27 |
| OvenWerks | *starts jack | 20:28 |
| shaban238 | ah ok thank you :) | 20:28 |
