| ArgentinaTango | Hi | 02:25 |
|---|---|---|
| ArgentinaTango | I install an Ubuntu Studio to make my phd thesis | 02:25 |
| ArgentinaTango | But in the start have a lot of problem with video | 02:26 |
| ArgentinaTango | Can someone help me? | 02:26 |
| n4dir | I probably won't be able to help, but for others to help you should probably tell your graphics chipset (if i understand your problem correct) | 02:28 |
| n4dir | lspci -k | grep -A3 -i VGA | 02:28 |
| n4dir | i think | 02:28 |
| ArgentinaTango | Where i see the model? | 02:30 |
| n4dir | the first line. You could just do "lspci | grep -i VGA". | 02:31 |
| ArgentinaTango | Maybe Gforce 210 | 02:31 |
| n4dir | -k will add the driver in use, which is the last line. But, bad news, i am not in such problems. (mainly intel over here) | 02:31 |
| n4dir | if i am not wrong this time this channel isn't outstanding active. So if in doubt ask at another time. Good luck | 02:32 |
| ArgentinaTango | gt218 nvidia corporation (gforce 210) | 02:32 |

| bastien | OvenWerks: Thank you for your advice. I'm going to look for an application to see CPU activity, that's a good idea. Concerning my AMD, the "governor" is in "performance" mode, and the "boost" option is not available. In the bios, I disabled a "quiet&cool" option, but I just saw a "Core performance boost" option that I might need to disable. The low latency core is well installed. | 07:35 |
| bastien | OvenWerks: Have you made some of your settings in your motherboard bios, too? Maybe I'm looking in the wrong place :) | 07:36 |
| bastien | I could only try all this out tonight: I'm at work right now :(. | 07:39 |
| MauroGaspari[m] | [bastien](https://matrix.to/#/@freenode_bastien:matrix.org) in my experience, the hardware interface quality and how you set it up, is what makes the biggest difference with xruns. When i plug a good audio interface to my systems (I have both amd and intel), no cpu tweaks make a real difference. If you are sure you previously used the same interface in another computer, it might be worth checking what changed | 09:19 |
| MauroGaspari[m] | in the new one in terms of interface drivers, or usb power/drivers, or see if there are any important firmware updates for your interface. | 09:19 |
| MauroGaspari[m] | Also try to search the net if the interface you are using has reported driver bugs or regressions. What I am trying to say, try to broaden you troubleshooting instead of focusing on one thing too much. I hope it helps. | 09:19 |
| bastien | MauroGaspari[m]: thanks. Indeed, all the tests I have made (tweaks processor) have very little influence and do not solve the problem. In fact, the only thing that changes is the computer: it is much more recent. The audio interface is the same (I moved it), and my old computer was also running on the same version of ubuntu studio. So, I might look at the "usb power/drivers" side, I don't know if there | 11:27 |
| bastien | are any tools to help me (apart from testing all the usb ports). It is a scarlett 2i2 3rd gen interface. | 11:27 |
| MauroGaspari[m] | bastien: I don't have that one but I remember of people in the linux community reporting some minor issues and fixes. I will try to see if I can find those posts and get back to you | 11:32 |
| bastien | MauroGaspari[m]: thanks. The audio interface works well, apart from the fact that I find my latency too high compared to the computer I have (higher than on my old computer). | 11:36 |
| MauroGaspari[m] | for my USB interface, this is how I have Jack Master Settings. For me switching sample rate to 48000 and jack periods to 3 helped quite a bit. | 11:58 |
| * MauroGaspari[m] uploaded an image: jack-master.png (67KiB) < https://matrix.org/_matrix/media/r0/download/matrix.org/tTYencVrSZcLtMMvnAGhWNbY/jack-master.png > | 11:58 | |
| bastien | MauroGaspari[m]: it is my actual config, excepting buffer size set to 512 to avoid xrun | 11:59 |
| bastien | (and it is big buffer size comparing the computer : ryzen 3400g and 16Go) | 11:59 |
| MauroGaspari[m] | bastien: woah 512 on a scarlett seems way too high. | 11:59 |
| bastien | MauroGaspari[m]: yes ! that's why i asked lot of question her :( | 12:00 |
| bastien | *here | 12:00 |
| * MauroGaspari[m] sent a long message: < https://matrix.org/_matrix/media/r0/download/matrix.org/EOuZuHurBQqpXWxeHHsqBAHN/message.txt > | 12:14 | |
| bastien | MauroGaspari[m]: OK, I'm at work right now and I don't have the computer in front of me, but : 1 - Yes, Real time permissions is enabled. 2 - uname -a said i use a lowlatency kernel (which i have installed). 3- No power saving software is installed, my ubuntu install is quite fresh :). 4 - Bios was updated, I will look the usb port settings, but i don't touch it, it's the factory default. 5 - I will do | 12:22 |
| bastien | the full power off, and 6 : i try different usb port, but not all usb port (same problem), i will. | 12:22 |
| bastien | In any case thank you for these ideas, I'll try it tonight when I get home and give you the result (for the full poweroff and the usb ports) | 12:24 |
| bastien | To precise the 4, i try all USB2.0 port on the motherboard. The other are USB3, but i will try these too. | 12:24 |
| bastien | (scarlett 2i2 has usb2 connection) | 12:25 |
| MauroGaspari[m] | bastien: I wish you a good day and good luck with JACK! | 12:25 |
| bastien | Thanks :) | 12:26 |
| OvenWerks | bastien: my i5 does not have hyperthreading so I don't have to turn it off. I was able to do so when I was running an older P4. But even there the only difference it made was with latency of 64/2 and lower. I was able to get my PCI audio down to 16/2. USB will never get that low as the transfer rate is 1ms (16/3 at 48000) and in such a case you need to double that for reliability. So 32/3 is about | 16:38 |
| OvenWerks | minimum. Also, it makes a difference which physical USB plug one uses. | 16:38 |
| OvenWerks | A lot of the newer motherboards internally route all the USB 1/2 ports to one bus and one irq. | 16:41 |
| OvenWerks | this means your mouse ends up being at the same priority as your audio IF :P | 16:41 |
| OvenWerks | it is almost best to install a USB PCIe card to use just for the audio IF and make it's IRQ a higher priority and the MB USB a lower priority. | 16:43 |
| OvenWerks | In my case I was able to turn the MB USB3.0 stuff off so now the USB is split into two parts with the ehci (USB2) driver. One for front and one for rear) | 16:45 |
| Maik | Eickmeyer: ping | 19:11 |
| Eickmeyer[m] | Maik: Pong? (standby) | 19:12 |
| Maik | Eickmeyer[m]: maybe it's better i take my question offtopic since it's not Studio support related | 19:13 |
| Eickmeyer[m] | Maik: Sure | 19:13 |
| Maik | i forgot you guys had a offtopic channel too | 19:13 |
| citadel__ | Hi, Audacity breaks my audio (studio 20.04) https://pastebin.com/pyMN40Aa | 22:18 |
| Eickmeyer[m] | citadel__: Like I told you elsewhere, you have a weird plugin from kxstudio likely. Some sort of incompatibility. | 23:57 |
| Eickmeyer[m] | !kxstudio | citadel__ | 23:57 |
| ubottu | citadel__: KXStudio is a software repository for Debian-based operating systems for audio production. It is not supported by Ubuntu or Ubuntu Studio, and using its repo is highly discouraged as it can overwrite system and user settings. Support in #kxstudio. See also https://askubuntu.com/a/1249739/952110 | 23:57 |
| Eickmeyer[m] | Long-story short, we can't support systems that have added that repo here as it creates a franken-Buntu. | 23:59 |
