What is you sound setup?
Is it pulse-audio->jack->alsa, then
you should check what is set as output device in your pulse audio configuration, if you use jack it should be "pulse audio jack sink".

"paman" program can help you troubleshoot pulse audio.

Do it as described in the image, try to set real time priority to 50 or even 89.

try it, you can set real time priority to about 50.

The governer is being changed fine, but he CPU frequency is unaffected. one more idea: try this to see what is cpu max freq on your system: cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq and this to see what cpu frequencies are availble on your system - cat /sys/devices/system/cpu/cpu0/c...

JACK failed to start with USB Audio 0 as its ALSA device. It did start with USB Audio 1, but there was no sound. OK, but this comand worked for you jackd -P89 -dalsa -dhw:Audio,0 -r48000 -p1024 -n3 -m -P Starting jackd manually seems to work. I've tested several applications that output to JACK, an...

GrayBoltWolf, can you post output of commands: and also log from jackd (click messages in qjackctl)

Duplex mode wasn't enabled, and starting JACK with a lower buffer didn't make a difference, but I've managed to resolve the issue. According to your log duplex mode was enabled, there is a bug in cadence. Since the E10K is a DAC and an amplifier, it's likely that what Cadence is labeling as USB Aud...

http://kxstudio.linuxaudio.org/Documentation:Manual:jack_configuration Input device, output device in my pinion should be the same because it won't synchronize in realtime. Anyway jackd don't synchronize them, so you can try to setup jack with one device, that is set your fiio for playback, turn of...

Try to change to performace governor with this command: Is it working?
Is this command showing errors?

You are running two cards one for playback and other for recordning it's wrong. choose only "one" card, this two won't synchronize. Try 512 frames and 3 periods, you don't need super low latency for music listening. ---------------- if it won't help you can try run jackd manually: Can you ...

It looks that everything is working with another sound card...

Have you tried to use cadence "stop" "force restart" "configure" features?
"stop" is not working?
Can you post also:

Can you post the output of commands (best run it as root) so we can see what processes are accessing sound devices and if jackd, pulseaudio are running?

What cpu governor is working in your system? Can you post output of this command: cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor I have used this command to change cpu governor to performance: echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor The best forum to a...

try pianteq as a remedy for sampled piano, bitwig as a substitute for ableton and j.e.f.f.g posts http://linuxmusicians.com/search.php?au ... 1&sr=posts as source for sampled orchestra

Is there an audio interface that I can use also as mixer

Mixing live band itb is very risky.
I would use analog mixer and audio interface for recording, look for delta 1010, presonus 1818vsl, adat card + ada8000.
