Re: Unubtu20.04 /linux-image-5.x-lowlatency, useful or not?

On my notebook computer (Core i7) I have perfect results with a lowlatency kernel and quiet splash acpi_irq_nobalance nowatchdog nohz=off intel_idle.max_cstate=1 So I use intel_pstate. I disable some stuff that might get in the way in /etc/modprobe.d/blacklist-audiotuning.conf blacklist bluetooth bl...

Re: Basic USB stereo line in/out device?

Can someone recommend a compatible inexpensive stereo line in/out to USB device so that I can record and monitor from my hardware mixer? Balanced connections are preferred, but unbalanced is ok too since it will be a very short run from the mixer to laptop. I tried getting along with a Zoom portabl...

Re: jack shows scarlett 2i2 but not in any DAW

I get no clue out of this. The graph says that jackd is running and uses the builtin audio interface. But it was not possible to start jack with the USB interface.

Re: Do you find it hard to work on more than one recording at a time?

When I work on doing a recording of a song, it's usually a process over several weeks, and I find during that time period that the song takes over my brain. I find it impossible to work on multiple songs in parallel, it's like as soon as one song takes over my brain I find the other one repulsive t...

Re: Ultralite AVB

3. Any kernel 5.8.X + Drumfix's module + setting USB host smp_affinity to use a single CPU + kernel boot options "acpi_irq_nobalance nowatchdog nohz=off intel_idle.max_cstate=1": rock solid 24 hours of sound without any issue. WIN! In terms of tweaking, everything else seems to make no difference. ...

Re: Ultralite AVB

I'd start with only blacklisting the bt and video drivers. AFAIK the governor doesn't matter if you use the intel_pstate driver: root@bubu:~# cpufreq-info | grep pstate Treiber: intel_pstate Treiber: intel_pstate Treiber: intel_pstate Treiber: intel_pstate Treiber: intel_pstate Treiber: intel_pstate...

Re: Focusrite Scarlett Gen 3 4i4 (and others)

Is Focusrite Scarlett currently good enough to work with Laptop? I'm mostly interesting about 2nd gen and 3rd gen. Since my old firewire laptop is too rare (more than 10 years old), I need to switch to new laptop and find a good card for rehearsals/concerts. From Scarlett I mostly need 48 kHz sampl...

Re: Ultralite AVB

1. Something closely related to USB communication in some hardware that makes the Ultralite totally unusable, as you get artifacts and then silence in a few seconds of operation. This happened to my Lenovo X1 Carbon. For this situation, my solution was disabling EHCI and compiling xHCI as module in...

Re: Audio Interface for Linux -- Mackie, MOTU, Presonus, ?

I've used both FocusRite Scarlett and the Behringer UMC line on my Linux rigs, and both get good results. I was wondering about https://motu.com/products/proaudio/8pre-es - it says it works with Linux using a web interface? I remember MOTU absolutely shitting all over the Linux community when I was...

Re: Ultralite AVB

I wonder if it's the ehci module that makes trouble.

I have no problems at all and

Code: Select all

cat /proc/interrupts | grep ehci
returns nothing.
