same error as before check if QjackCtl settings changed to 2 capture channels
reboot system if new settings are not being recognised

when JACK is started with 2 capture channels, the alsa_in command can add the other 2 channels

Could you use Patchage instead of Catia?

I suspect you have jackd installed if Cadence cannot see it

if jackd is replaced with jack2 the same start command should work - /usr/bin/jackd
but if jackd was replaced with jack-dbus may need to adjust start command to - /usr/bin/jackdbus

modprobe option snd-intel-dspcfg dsp_drivers=1 replaced an earlier modprobe option snd_hda_intel.dmic_detect=0 https://bugzilla.kernel.org/show_bug.cgi?id=205959#c4 both options disable the internal digital microphones so that the rest of the audio codec works with Legacy driver snd_hda_intel Legacy...

ALSA: cannot set channel count to 4 for capture ALSA: cannot configure capture channel if JACK cannot start with 4 capture channels, try starting with only 2 channels and add the other 2 later This interface will probably have 2 subdevices in ALSA (see aplay -l ) each subdevice will be capable of 2...

i have an internal audio card with similar layout in ALSA (2 stereo subdevices for capture and playback) I use alsa_in and alsa_out commands with QjackCtl to add the 2nd subdevice and has always been reliable select the first subdevice in Cadence/Qjackctl - for OP this is hw:Pro,0 and set the channe...

To add another Pulseaudio JACK Sink to Pulseaudio pactl load-module module-jack-sink this will create 'Pulseaudio Jack Sink 01' repeat the command to add more sinks audio streams can be routed to the different sinks in Pulseaudio Volume Control Playback tab - 'pavucontrol --tab=1' use drop-down menu...

if JACK is started + both cards have Pulseaudio Profile set to Off
then need Pulseaudio JACK Sink for audio playback to JACK

if not already added when JACK started

I want all audio go trough the internal soundcard (without jack) and all going trough the external one when jack is started for external soundcard set Pulseaudio Profile to Off if Pulseaudio is not switching from internal soundcard to jack_out default sink, can change internal soundcard Profile to ...

Pulseaudio default sink is saved to home folder in ~/.config/pulse/

to see current default sink: to change it to use Pulseaudio JACK Sink: OR install pasytray

check volume levels for the pulseaudio sinks pactl list sinks | grep -e 'Name' -e 'Volume' presumably null-sink is by-passing level control for regular sink set with level lower than 100% would get same level for recording if regular sink was set to 100%, but likely would be too loud for comfortable...

only 8 modules listed in pulseaudio is much lower than i would expect and except for JACK sink and source, no ALSA or Bluetooth devices shown for input or output listing for Bluetooth modules in /etc/pulse/default.pa is as expected for default but as Bluetooth modules not loaded, system may be using...

suggest check bluetooth modules in pulseaudio and

Lubuntu is good lightweight desktop and was a good base for a DAW when i used it

Should be not much difference to Ubuntu or Mint to add KX repositories and install

i find JACK works better at 48kHz compared to 44.1kHz with most audio interfaces

This appears to be a line level audio DAC device has USB connection from PC, 2*XLR outputs & a mono/stereo switch no hardware controls like some interfaces so level settings should be in alsamixer 'this unit complies with part 15 of the FCC rules' = class-compliant if it is visible in ALSA, suggest ...
