Hi!
Installed a new kernel on my Debian Testing machine with
kxstudio-"extension"
:~$ uname -a
Linux mmmaschine 5.9.0-4-rt-amd64 #1 SMP PREEMPT_RT Debian 5.9.11-1
(2020-11-27) x86_64 GNU/Linux
and had a new problem that jack couldn't launched - which bever had been
a problem, so far. Dived into journalctl -f and stumbled upon
Dez 04 11:18:17 machine pulseaudio[1852]: E: [pulseaudio]
module-alsa-card.c: Failed to find a working profile.
Dez 04 11:18:17 machine pulseaudio[1852]: E: [pulseaudio] module.c:
Failed to load module "module-alsa-card" (argument: "device_id="3"
name="usb-KORG_INC._KONTROL49-00"
card_name="alsa_card.usb-KORG_INC._KONTROL49-00" namereg_fail=false
tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes
use_ucm=yes avoid_resampling=no
card_properties="module-udev-detect.discovered=1""): initialization failed.
Knowing, that the Korg has no audio-abilities, I checked
:~$ cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0x4001110000 irq 134
1 [Loopback ]: Loopback - Loopback
Loopback 1
2 [DSP ]: H-DSP - Hammerfall DSP
RME Hammerfall HDSP 9652 at 0xa0100000, irq 17
3 [KONTROL49 ]: USB-Audio - KONTROL49
KORG INC. KONTROL49 at usb-0000:00:14.0-2, full speed
Unplugging the Korg Kontrol49 made it possible to launch jackd, again.
My questions:
How can I force my system not to handle the Korg as an audio but a MIDI
device?
Is this something happening on kernel level, so *someone*™ has to fix
stuff here?
Greets!
Mitsch
