@damentz I tried your suggestion but it didn't seem to improve things. I have between 3 and 4 times less xruns when using 1000Hz tick rate compared to the now default 250Hz. My test settings were a sample rate of 48000 Hz with 64 as the buffer size giving a latency of 1.3ms. I used the performance governor. I normally use 128 as the buffer size but I increased it in order to get more frequent xruns. An other observation is the schedutil is closer to the performance governor in terms of xruns at 1000Hz but there is a bigger gap between both at 250Hz.

I'm still wondering if it wouldn't make sense to keep 250hz as the default as my usage is quite an edge case I would say.

@Terence, try setting rr_interval back to 3 in /proc/sys/kernel. If that doesn't help, then it's the kernel tick frequency.

And thanks for reporting. Con has mentioned that the kernel tick frequency shouldn't matter and that MuQSS is "tickless". This may prove the opposite and that you still need a high frequency tick rate to support soft-realtime applications properly.

Let me know which of the two settings helps you the most - I'll update the configuration accordingly.

@damentz your changes introduced by https://github.com/damentz/liquorix-package/commit/d51bd77f2719e43528898a4db06af34aafd22bdf while being saner defaults degrades realtime audio/midi performances (more frequent xruns). Would only changing back the tick to 1000hz locally enough?

@Agafron:

Because 4.18.18-lqx patchset includes 4.18.18 from upstream.

Downloading linux-4.18.tar.xz

_major=4.18

_srcname=linux-${_major}

.........

source=("https://www.kernel.org/pub/linux/kernel/v4.x/${_srcname}.tar.xz"

Why is downloading linux-4.18.tar.xz instead of linux-4.18.18.tar.xz?

If anyone has an issue in building the kernel relating to:

When installing this kernel i get ERROR: module not found: `usbhid'

i'm happy to report that the package compiled and installed successfully. @damentz : your comment is informative; I didn't know that having not used makepkg before. I was unsuccessfully trying to edit the PKGBUILD variables to make it create the correct file. Thanks a lot for your input.

@sir_lucjan : about manjaro not being arch, i know that. I was thinking of using manjaro as a stepping stone towards arch, coming from a debian system. But, i have no complaints with the system i have now. Nor can i figure out a compelling enough reason to switch. In fact, this is the first issue i have had with aur since i installed manjaro, and i am pretty sure that this was an issue with aur helper yay and not manjaro itself. Thanks a lot for your comments and suggestions; they were really helpful.

There's probably multiple reasons why makepkg -sric solved your problem:

-s = --syncdeps - installs missing dependencies

-c = --clean - removes artifacts and work directories before building

-r = --rmdeps - removes installed dependecies required for build

It could just be you were missing dependencies and your work directory was dirty, had previous folders and files that were interfering with your build.

Manjaro != Arch

AUR is designed for Arch, not Manjaro
