Edit /etc/rtirq.conf with this :

Code: Select all

RTIRQ_NAME_LIST="xhci"

Then do

Code: Select all

$ sudo rtirq restart

Then post

Code: Select all

$ rtirq status

again.

Have you noticed any difference?

Still same scenario, endless stream of xruns the second i connect jack at 32


my max_user_freq is at 64, I dunno if that matters

[merlyn]

Debugging, eh? If you keep ruling things out you will get to the problem. Analysing what has happened so far : in the first rtirq status output there were two nvidia IRQs using 0.8 and 0.2 % CPU. It doesn't seem much, but they are wanting attention and could get in the way of the soundcard.

In my rtirq status output the radeon driver interrupt is using 0% CPU :

Code: Select all

308 FF      50   -  90  0.0 S    irq/30-radeon

IRQ 46 is probably your soundcard because it is using some CPU. In rtirq.conf names are preferred because the numbers can change on successive boots.

You've got a powerful chip so you should be able to do better. You could try starting JACK with the internal soundcard to see if it's a USB problem. I haven't seen a list of IRQs that are all xhci. Must be a new thing. There is the possibility that you could do something about that in the BIOS -- a setting like 'enable legacy USB' or something like that.

[christobal]

It's the exact same behavior with the internal card.

BIOS will have to wait, after changing a setting the other day to allow for resizable BAR support, I only get display before OS through HDMI, which I dont have right now

[merlyn]

It's the exact same behavior with the internal card.

That rules out a USB problem. This leaves trying a different graphics card or the nouveau drivers. Now, before @sysrqer jumps in to point out how rubbish the nouveau drivers are this would just be to identify the problem, not as a long term solution, as the nouveau drivers are not the best.

Motherboards don't always have built in graphics these days but if you do you could try that.

[christobal]

The problem was there as I said on AVLinux with rt kernel and nouvou - since AVlinux does not support third party drivers.

[christobal]

I just tested the interface on my friends windows computer, where it runs 96k/32 without any problems. So it's not the card at least.

I tried 96/256 to get latency down, but I do more xruns than I would like there also with both Ardour and Bitwig.

Mostly these:

Code: Select all

Fri Dec 11 19:53:15 2020: ERROR: JackEngine::XRun: client = Bitwig Studio was not finished, state = Running
Fri Dec 11 19:53:15 2020: ERROR: JackAudioDriver::ProcessGraphAsyncMaster: Process error

Fri Dec 11 19:43:29 2020: ERROR: JackEngine::XRun: client = ardour was not finished, state = Running
Fri Dec 11 19:43:29 2020: ERROR: JackAudioDriver::ProcessGraphAsyncMaster: Process error

Edit: After trying all the different kind of hz/buffersize combinations, it seems the problem arises when the block latency goes below whatever combination gives 5.3 ms to whatever combination gives 2.7 ms. No matter the combo at 2.7 there are x-runs. Varying amount depending on freq/buffer.

As long as I keep it at a combination that gives 5.3 (for example 48/256, 96/512, etc) there are no problems really. Still, very odd.

If you told me you had a fast, multi-processor chip and were getting 'good' for everything on realtimeconfigquickscan I would expect your system to go like a rocket so you have my sympathy that that is not the case.

Some ideas

- Borrow an AMD graphics card
- Try a Liquorix kernel
- What options are there in the nvidia control panel? I remember putting the power profile to 'performance' for the nvidia card.
- Any options in the BIOS when you get a chance to look at it?
- Rather technical but what speed of memory does your friend have? Is it the same as yours? There is this 'infinity fabric' thing where Ryzens perform best with a 1:1 relationship between the infinity fabric clock and the memory clock. (long shot).

I hope you can resolve this, partly because I was thinking about getting a Ryzen

Yeah I'm quite perplexed to be honest, haha. I'm considering installing Win10 just to see if it's hardware related, I just can't be bothered right now, I only have one harddrive and everything else is set up real nice right now.

Haven't been able to look into the BIOS more yet no.

We have the same RAM, and I am at 1:1 (3200mhz/1600)

Nvidia is at performance.

My CPU even boosts far higher than his with better temps because of his shitty fan setup. (I dunno how accurate gtkstresstest is in reporting clocks, but my max boost clocks range between 4350 - 4700 on different cores, something that honestly sounds a bit high even if it's just for a second).
