Re: Xruns on linux mint 17.2 and kxstudio software

Sorry FalkTX, I assumed wrongly that there was an optimized kernel in the KX repos - never used those actually. In my experience (Arch Linux), RT still has a small edge over non RT (let's ~2-3ms second latency vs ~3-4ms), but it's for sure not as dramatic as it used to be. For the sake of troublesho...

Re: Xruns on linux mint 17.2 and kxstudio software

The kernel is not detected as RT:
Kernel with Real-Time Preemption... not found - not good
Kernel without real-time capabilities found
For real low latencies (in the 2 ms ballpark), I think you still need the RT patchset.
Are you sure you're using the kernel from the KX repo?

Re: Xruns start to increase after ~5-10minutes

I was actually referring to wineasio with jack2 and 64 bit apps, as I remembered seeing some thread where jhernberg (wineasio dev) gave a word of caution. ok, just found it (2nd comment): https://aur.archlinux.org/packages/wineasio/?comments=all But you're right, I misread - 64 bit should work &...

Re: Xruns start to increase after ~5-10minutes

Out of the blue, that sounds more like a wine-rt/wineasio issue. Also, last I remember wineasio doesn't quite work with 64bit apps - advice is to stick with 32 bit. Did you set up the env variables "WINE_RT" and "WINE_SRV_RT" = is wine-rt actually doing its thing? What are your e...

Re: Problem with ulimits

It looks like your limits.conf is getting ignored.
Did you include a carriage return at the end of the file?

Re: Linux Mint, Jack and pulsating sound

That Rocksmith Tone Cable is not a simple analog guitar cable, it's a cable + Analog to Digital converter (= jack to usb audio interface). While this means implicitly that it kinda works on linux, I see a problem here. As I understand your setup, this means that you are actually 2 different audio in...

Re: bitwig now has touch support

yep, some interesting features there. This radial menu could make fat desktop applications work a bit better with touch screens.
Now the 100$ question: who's got a graphical environment with multi touch actually working on linux to try it and report back?

Re: normal Linux kernels with threadirqs vs RT patchset

update-grub overwrites /boot/grub/grub.cfg, so you could first check if threadirqs made it there (which would indicate that the command was successful). or, on the boot menu, just press "e" to see what is appended to the boot parameters. Once booted, the simplest is probably to read the ou...

Re: Clean linux-generic

What distro? Regardless: unless you have a space problem, advice here is to keep the stock kernel around. You never know when you'll need it - be it because of a compatibility issue, performance comparison purpose, etc... It's always safer to have a known good kernel to boot from if things go wrong ...

Re: normal Linux kernels with threadirqs vs RT patchset

There's a boot parameter to activate, so you would probably know it if it was enabled. I don't remember very well but you may also see the threads in a task manager/top/htop/whatever (or with rtirq.sh status), With GRUB that would look something like: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash th...

Re: Pro audio on a SSD drive Laptop

For audio work on a notebook, I'd say you did well with the cpu choice. The main difference between an i3 and an i5 is the turbo boost feature that will inevitably push the thermal envelope beyond what it should be, which has the nice effect of causing throttling - the last thing you want during aud...

Re: jackd synchronous mode: do this exists anymore?

OK, so at least I'm not crazy (unless we are 2 in that case ;-) ) The small latency difference between channels is not really a problem for my small config, but I can understand why those cards may not be suitable in a professional context... My concern is just to get consistent results when testing...

Re: jackd synchronous mode: do this exists anymore?

Thanks for the explanations guys, that helps a lot. I pushed it a bit further and included jack1 to the party, and compared with jack2 in synchronous and asynchronous modes measured with jack_iodelay on my Scarlett 2i2. No precise numbers as I didn't take any note, just some overall impressions: - j...
