Comment # 2 on bug 1194099 from Takashi Iwai

Could you identify exactly which packages have been updated by the breaking
update?  If it's about the kernel, try to boot with the older kernel and see
whether the problem persists or not.

In anyway, please give alsa-info.sh output at the broken state.  Run the script
with --no-upload option, and upload the output to Bugzilla.  Take the
alsa-info.sh outputs at both the headphone plugged and unplugged.

If the older kernel works better, please upload alsa-info.sh output from that
kernel as well.
