Comment 27 for bug 1414706

This seems to be a tricky one. I was wondering if we can also make a coef dump. To do that, please do the following:
 1) revert any changes done with hdajackretask or /etc/modprobe.d/alsa-base.conf
 2) on top of 14.04, install the latest daily dkms package (from the alsa-daily PPA)
 3) reboot
 4) (as root) echo 1 > /sys/module/snd_hda_codec/parameters/dump_coef
 5) start recording to headset mic and confirm that the bug is present (records buzzing noise instead of clear sound)
 6) while recording is active, dump alsa-info
 7) attach alsa-info (or a link to it) here

Thanks!
