This symptom certainly isn't specific to any hardware and must be
caused by the specific applications that are polling the device via

Please do not assign bugs to the ubuntu-audio team unless we
specifically request it. It's rather rude, and the torrential bugs
mean that your report is likely to slip through the cracks.

I've changed the affected source package to phonon -- yes, likely
incorrect -- in the hopes that someone more familiar with Kubuntu's
configuration can take a look.

apport-collect -p alsa-base 521424

is a starting point, but I want to reiterate that this symptom isn't
an audio stack issue.
