This looks related:

[ 4849.250374] Audio Port: ASoC: no backend DAIs enabled for Audio Port

Also, your USB mass storage device may have troubles. (Probably not related to this.)

Thanks

[Seth Arnold (seth-arnold)]

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

[Daniel van Vugt (vanvugt)]

I agree, that looks relevant:

[ 4849.250374] Audio Port: ASoC: no backend DAIs enabled for Audio Port

which comes from the kernel, sound/soc/soc-pcm.c:

        /* there is no point preparing this FE if there are no BEs */
        if (list_empty(&fe->dpcm[stream].be_clients)) {
                dev_err(fe->dev, "ASoC: no backend DAIs enabled for %s\n",
                                fe->dai_link->name);
                ret = -EINVAL;
                goto out;
        }

The same hardware is mentioned in https://bugzilla.kernel.org/show_bug.cgi?id=189261, although it appears that's not what the original reporter of that bug has.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1768991

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.
