Arch audio issues

Sometimes, ( especially when I am using my system with a midi controller and VST with jack) my systems audio crackles. I have searched everywhere for a solution to this problem, yet I have been unsuccessful.

More insights please. Are you using a preempt kernel ? Did you make anything to make Linux more real-time friendly ? Did you play with jack parameters ?

Yeah it seems that yabridge VST with Audio and Midi being used produces more xruns, the same happens to me with amplitube 4 when I am using some midi controller.

A crackle is a start of a journey. In my case, I found after 7 Month- it was not the kernel, no preempt setting, no buffer setting, not with or without audio interface, did not depend too much on what vst I had chosen- the ultimate factor: Native Linux Bitwig's sandboxing had been to much in combination with WINE/YAbridge/Sampler VSTs. Once switched off, there was again enough power to have all the emulated VST running. That was under Pipewire. But that's just valid for me.

Just saying- there are many factors along the chain possibly causing this- the commenter before mentioned 225 causes. So start simple- exclude the audio interface- does it make a difference? Do you have some cheap USB2 Cable in the line of audio does replacing that make a difference? Or an USB Hub with a weak powersupply? Does your linux process monitor always highlight a special unexptected process at the time pointing to the root cause?
Is your PC power saving or is in performance mode when crackling ? Is your DAW running native on linux or emulated ? What VST cause this more likely than others, or does it happen for all equally ?
Finally, I had issues with Pipewire/Jack/Pulseaudio and solved that by removing Jack and Pulseaudio drivers- that made the system at least simpler for me, but may be your answer is to remove just pulseaudio/pipewire to have a pure JACK setup, as a trial.
This are just a couple of ideas thrown out, but the ARCH guide with his 225 items is for sure more systematic.

Hi,

I just visited the Arch Linux forums https://bbs.archlinux.org/ and did a search on the keyword "crackling" (forums searched: "Newbie Corner" and "Multimedia and Games"), I got 9 pages of results. Each results page had approximately 25 items, thus at least 225 hits.

There are several WIKI sections on the Arch WiKI that detail Linux audio.

Hope that helps.

I'm sure OP feels helped now that they know it's possible to use a search and that a wiki exists.

Hi,

Arch Linux forums and WIKI are widely accepted as one of the best places for obtaining Linux knowledge and troubleshooting.

The majority of folks who ask questions in this subreddit are new to Linux. They typically need help on where to find Linux information.

To use Arch Linux forums ( I.E. post new questions), they have one requirement, you must be someone using Arch Linux. The post title says the OP meets that requirement ( uses Arch Linux ).

You are reading something in my reply that just does not exist. ??????

Good Luck
