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
