Comment # 27 on bug 968744 from Takashi Iwai

Ah, you test with the latest kernel.  No, what was requested is to test these
two kernels: the last working kernel (3.16.7-7) and the first broken kernel
(3.16.7-21).

Let me rephrase the test procedure:
- Add the module option to snd-hda-codec as described in comment 24

- Then boot to 3.16.7-7.  Confirm that the sound works.  Then take alsa-info.sh
output with --no-upload option once.

- At next, boot to 3.16.7-21.  Confirm that the sound doesn't work.  Then again
take alsa-info.sh output with --no-upload again.

- At last, boot back to 3.16.7-7 again.  Then reconfirm that the sound still
works.

- After confirming these three steps, upload the alsa-info.sh outputs of these
working and non-working kernels to Bugzilla.

In that way, we can compare the results directly side-by-side.
