When I was playing with a headset at the weekend, I noticed stack traces
in the kernel log, in the area of ALSA (snd_pcm_...), I think at the
same times as I was plugging and unplugging the headset.

So I think there's a significant SW element here - which is good,
because we can probably fix it eventually.

Of course, your precise experiences may still be different from mine...
