Please can you look into this. It has been marked as Invalid, however, it is not a support request as has been assumed. My card is a card 1: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) [] Subdevices: 0/1 Subdevice #0: subdevice #0 uname -a Linux rtx 5.8.0-50-generic #56~20.04.1-Ubuntu SMP Mon Apr 12 21:46:35 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux All software has been updated to the latest versions. With the default configuration jackd -R -d alsa -d hw:1,0 ...

This value must be a power of 2, and the default is 1024. And the current situation is that the only way jackd starts is with a non power of 2. Also buffer sizes of 240, 120 works jackd -R -d alsa -d hw:1,0 -p 240 creating alsa driver ... hw:1,0|hw:1,0|240|2|48000|0|0|nomon|swmeter|-|32bit configuring for 48000Hz, period = 240 frames (5.0 ms), buffer = 2 periods jackd -R -d alsa -d hw:1,0 -p 120 creating alsa driver ... hw:1,0|hw:1,0|120|2|48000|0|0|nomon|swmeter|-|32bit configuring for 48000Hz, period = 120 frames (2.5 ms), buffer = 2 periods FYI a buffer size of 48 also works however I get another message (maybe because I am not running with a low latency kernel ... yet) Please see attachment for details. ** Attachment added: "jack_buffer_bug.txt" https://bugs.launchpad.net/ubuntu/+source/jackd-defaults/+bug/1872244/+attachment/5491789/+files/jack_buffer_bug.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872244 Title: Jack audio not working on Ubuntu 20.04 running on a Thinkpad Carbon X1 (7th gen) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jackd-defaults/+bug/1872244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Daniel, thanks for the workaround! It works! I can confirm that JACK not
starting on SOF can be fixed by just setting the period to 1008 or 2040.
I'm on Dell G5.
However, JACK with such a setup is completely unusable for me. All
applications produce noise instead of proper sound, probably expecting a
power of 2 frame sizes. The only setting which helps somewhat is "Force
16-bit" ("works" only for period of 1080, not for 2040) which makes the
sound almost normal, but with crackling distortion.

Hi all, I think we're confusing OP, who is using the correct 7th gen audio interface, with someone who chimed in with their 2nd gen audio interface aplay results. I've got a solution. The period that this driver uses is an EXTREMELY non-standard 1008 samples. I discovered this by making a dummy jackd server and adding the card manually via alsa_in: [19:36:16]daniel@daniel-ThinkPad-X1-Carbon-7th:~> $alsa_in -d hw:CARD=sofhdadsp,DEV=0 -r 48000 WARNING: buffer size does not match: (requested 2048, got 2040) WARNING: period size does not match: (requested 1024, got 1008) selected sample format: 32bit delay = 4208 delay = 1022 Anyway, the solution here is to use a period of 1008. This can be assigned in qjackctl by typing it in instead of using the dropdown, or via cli with the `--period 1008` option. Some audio applications will need additional config. For example, supercollider requires a 2^n block size that is a factor of the sample rate. This can be achieved by executing `s.options.blockSize = 16;` before booting the server. Other than the bizarre period, most of the defaults work quite well. Obviously this can be tuned, but at a bare minimum, jackd can be successfully started on my machine via: [02:37:47]daniel@daniel-ThinkPad-X1-Carbon-7th:/usr/lib/firmware/intel/sof-tplg> $jackd -d alsa --period 1008 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872244 Title: Jack audio not working on Ubuntu 20.04 running on a Thinkpad Carbon X1 (7th gen) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jackd-defaults/+bug/1872244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Just a tip. The best thing to do when it is a support request rather than a bug, is to convert it to a question. See the option near the top-right. I will do it. ** Changed in: jackd-defaults (Ubuntu) Status: Invalid => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872244 Title: Jack audio not working on Ubuntu 20.04 running on a Thinkpad Carbon X1 (7th gen) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jackd-defaults/+bug/1872244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Based on Len's response, this seems more like a support request. As such, per Launchpad policy, this does not belong on a bug tracker. Please use appropriate support forums, such as askubuntu.com, in the future. ** Changed in: jackd-defaults (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872244 Title: Jack audio not working on Ubuntu 20.04 running on a Thinkpad Carbon X1 (7th gen) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jackd-defaults/+bug/1872244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

"internal audio interface (hw:sofhdadsp)" I am wondering where you got the "hw:sofhdadsp" from was PCH,0,0 not listed? from your output of aplay -l it would seem the device you want is hw:PCH,0,0 or just hw:PCH even. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872244 Title: Jack audio not working on Ubuntu 20.04 running on a Thinkpad Carbon X1 (7th gen) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jackd-defaults/+bug/1872244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So in digging through this I got mine working. I am on a 2nd Gen X1 Carbon and have been getting the same error. At least in my case it seems alsa is not selecting the correct audio device, preventing jackd from starting. When run manually it works: I listed my alsa devices with this: $aplay -l Which returns a list of audio devices including the one I want (card 1, device 0): --- card 1: PCH [HDA Intel PCH], device 0: ALC3232 Analog [ALC3232 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 --- I then run jackd manually with this command: $jackd -R -d alsa -d hw:1,0 And it works. From there, I was able to manually adjust any of the GUI tools like qjackctl or Ardour and they are now working. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872244 Title: Jack audio not working on Ubuntu 20.04 running on a Thinkpad Carbon X1 (7th gen) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jackd-defaults/+bug/1872244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
