Re: Jack fails to start
@redu
If you now have the packages, i mentioned above, i suggest you to go back to qjackctl. Try to disable/change the capture device. The log says that it cannot initialize capture device. So try at first to start Jack on playback only.
@Kott
I am maybe old-school, to have much higher demanding settings, than needed.
But i know that you cannot recreate the values, from the screenshot below. The difference of bothering to tweak the system and use Linux-RT.
And you don't need to demand such behavior from your computer, but i do. And Linux really allows me.
And by the way, you are using Jack2 (1.9.12)

It's a bug!
Johan Andersen proposed here a fix, but it doesn't help in my case.

Re: Jack fails to start
Accidentally:
hw:sofhdadsp turned in my laptop to hw:PCH
This happened for instance in Qjackctl / Output device and Input device boxes.
Jack server now starts!
Also
jackd -d alsa -d hw:0
now starts Jack.
[Solved]
But what actually happened? I would like to understand, as one more "Cannon Point-LP-laptop" should be fixed the same way?
At the moment of this weird turn over, I kept playing with the Alsamixer app.
Anyone? What is this?

Re: Jack fails to start
In an earlier post you got this from aplay -l :
Is that what you still get? To get something different would seem weird unless you updated your kernel and got a new module that recognises 'sofhdadsp' and gives it a more generic name.
If it works on one machine logic would suggest it will work on another machine with the same sound hardware. I'm not sure how relevant a Cannon Point chipset is. What is relevant is this 'sofhdadsp' sound chip.
Code: Select all
edu@ENVY2:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) []

Re: Jack fails to start
Yes, it was changed:
redu@Yoga-C740-15IML:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC285 Analog [ALC285 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
etc ....
Kernel was not changed.
Settings / Sound / Input is now grayed out. Video play-back works, but microphone and other input devices??

Re: Jack fails to start
Learned later, that this line
options snd-intel-dspcfg dsp_drivers=1
was added to /etc/modprobe.d/alsa-base.conf
Nice, but now microphone was muted. There is nothing in Settings/Sound/input drvices.

Re: Jack fails to start
When you use JACK do you get inputs and outputs?
You can see if ALSA recognises inputs with :

Re: Jack fails to start
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 driver snd_hda_intel does not support the new Intel SST DMIC microphone array but should support a headset or similar analog microphone
there appears to be only a feature request posted about use of JACK on the SOF github site

Re: Jack fails to start
nikgnomicradio,
agreed fully!
1.
Today I can manage with PCH drivers and headphone mic.
2.
Hopefully sndhsdpa gets fixed in kernel some day. Now inside mic works, but jack server refuses to co-operate.
Many thanks for good discussions!
