Issue/Bug Description: Updating Operating System via Pop!_Shop, which installs/updates the following components,

3 components with updates:
 • alsa-base ALSA driver configuration files Version: 1.0.25+dfsg-0ubuntu5
 • linux-sound-base base package for ALSA and OSS sound systems Version: 1.0.25+dfsg-0ubuntu5
 • pop-desktop Pop Desktop Metapackage Version: 1.5.0~1608319383~20.10~825bd26

causes audio issues after reboot. Precisely, the system fails to detect the USB Audio Interface that worked prior to the update, using a different device for audio results in crackling, popping noises and other audio glitches.

I attempted to apply common fixes (eg. changing power saving options, buffer size and timing) for said issues, but none of them improved the situation.

Steps to reproduce: USB Audio DAC/Interface might be required to reproduce. Use the USB Audio Device, update the System Components to to listed versions, reboot.

Other Notes: After updating the System, I can purge remove alsa-utils and linux-sound-base to fix the issue, but updating the system also updates the components making the issue reaper.

@actuallyitschris: As a rule I would say that its a bad idea to remove those packages. However, sense you seem to have found a work around for your issue that requires their removal you can use the hold option to keep them from being installed after purging.

sudo apt-mark hold alsa-utils

sudo apt-mark hold linux-sound-base

If you find your system is less stable after holding these two back you can remove the hold like this:

sudo apt-mark unhold alsa-utils

sudo apt-mark unhold linux-sound-base

Again, I don't know if this is the right answer to the problem, but it is a possible solution.
