If you are on archlinux I don't think you need the audio group at all. In fact I think it conflicts with per-seat access to the soundcard, though I doubt that it has any practical consequences.

The RT CPU measurement has little to do with the CPU measurement, RT CPU is similar to JACK's DSP load, that is to say that it measures how much of the time available to process the audio was actually used.

A couple of years ago I spent quite a bit of time on this, and never managed it to be xrun free. Nowadays I use the pulse to jack bridge instead :) YMMV and all that.. :) Something to try might be to test the internal clients of JACK1/JACK2 to bridge to other soundcards. In the case of JACK1 check o...

In Renoise I get now ~+3 % DSP Load (Jack) with Dragonfly Reverb and +9% with Room. In Reaper I get +0% for Reverb and +0.1% for Room. :shock: @James: What are your numbers now? Strange that it's much worse in Renoise. That's most likely because of reaper's "anticipative fx processing". R...

Code: Select all

the irq/* threads normally run at priority 50.

There's a guide here: https://www.mixxx.org/wiki/doku.php/adjusting_audio_latency Scroll down a bit. On that guide it recommends running cyclictest as a normal user. When you start cyclictest you can watch the 'Max' field while you plug the power supply in. Because :) "Do not run the above com...

Not really :) Try with "sudo cyclictest -m -Sp98 -i100 -d0 --smi" You'd want the max to be lower than say 100us & no SMIs. This measure indicates how long it takes the kernel to schedule a thread. If there are huge delays then it will indicate some problem with the system. It's less of...

For A, you can refer to a device by name and not only index (which might change). If you look at the output of "cat /proc/asound/cards" the name is between the []. So you could use hw:Intel or similar.

Otherwise it's possible to set the index order by using modprobe.conf.

Could it be the hardware itself? BIOS code or something like that.

Do cyclictest results get worse when charging the battery?

I'm back home and currently testing again. I wonder(ed) why during the xruncounter test with the new script the CPU load is not evenly distributed across all 4 cores: Maybe because the audio processing is not parallelised. Yes that's it. Further I have: @audio - rtprio 98 @audio - memlock unlimited...

Maybe worth trying to disable SMT (hyperthreading) too. Thought it didn't matter for my i7, but recently I've discovered that running normal threads does indeed slow down my sched_fifo (realtime) threads.

I did not move my licenses off the W10 partition, but when I logged into Waves Central using wine, my licenses synced into .wine automatically. The licenses are attached to either the network card ID or if stored on USB, the USB drive serial number. If you disable your network card, the licenses wi...

IMO, be careful about deleting the prefix where you have waves plugins installed. I'm afraid that deleting the prefix would lead you to lose the license installed into the prefix.. You can rename it to something else though, so that you still have a possibility to go back and recover the license som...

I notice higher latency more on drums and guitar. With bass and keys I notice it less.

FWIW, I did install my Soundtoys plugins in wine a few months ago. Initially I had no problems at all, but at some point it didn't find the licenses anymore. Maybe it was related to updating the wineprefix with a new wine version. Soundtoys were very understanding and gave me new licenses! I'd urge ...
