[Jackaudio] Can't start with laptop speakers on Thinkpad Carbon X1 7th Gen and Ubuntu 20.04

[Dan Zink]

Hello all,

Sometimes I want to use jackd with the laptop speakers or headphones,
instead of my audio interface. I can't get it to start on my new laptop
(using the audio interface works perfectly, thanks community :) ).

I've successfully and mostly painlessly gotten jackd working on a few
different machines, but this one has me stumped. I'm going to try to
document as much as I can here so please forgive me if I miss something.


I'm using this version of jackd

$jackd -V
jackdmp version 1.9.12 tmpdir /dev/shm protocol 8



and this version of Ubuntu:

$uname -a
Linux daniel-ThinkPad-X1-Carbon-7th 5.4.0-45-generic #49-Ubuntu SMP Wed Aug
26 13:38:52 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux



Starting up selecting the first device under `aplay` throws this error
(using -R instead of -r doesn't seem to affect very much):

Using a dummy server succeeds:

When I list my devices (with the interface unplugged), with aplay -l I get:

$aplay -l

Has anyone else succeeded in getting jackd running with this particular
hardware? Thanks!
