[HDA Intel] output to hdmi:0 is heard through internal speakers as well

[David Henningsson]

As tested with
speaker-test -c 2 -D hdmi:0
as well as pulseaudio, sound is heard both through internal speakers (or headphones if connected), and hdmi. Expected it to go to hdmi only.

This typo caused the wrong codec's nid to be checked for wcaps type.
As a result, sometimes speakers would duplicate the output sent to
HDMI output.

[Luis Henriques (henrix)]

This bug is awaiting verification that the kernel for Oneiric in -proposed solves the problem ( 3.0.0-17.30). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-oneiric' to 'verification-done-oneiric'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Herton R. Krzesinski (herton)]

The commit for this bug came via an upstream stable release (3.0.21), thus marking as verification-done-oneiric.
