No HDMI-Sound anymore with onboard sound chip "Intel CougarPoint HDMI" after upgrading from Wheezy to Jessie

[mailing4362 <mailing4362@runbox.com>]

After fresh installing Debian Jessie (64-Bit) there is no sound anymore
on the TV connected via HDMI cable to the computer (mainboard Intel
DH67BL). With the OS installed before (Wheezy 32-Bit) it worked.

Onboard sound chip is:

# alsactl init
Found hardware: "HDA-Intel" "Intel CougarPoint HDMI"
"HDA:10ec0892,80862002,00100302 HDA:80862805,80862805,00100000"
"0x8086" "0x2002"
Hardware is initialized using a generic method

alsa-info.sh output is here:

aplay -l

I triple checked the alsamixer settings for muted channels and activated
all.

The following gives sound output on the rear panel normal
audio cable connected desktop speakers:
aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav

But no sound (and neither any error message) when using HDMI device
number 3:
aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav

It just plays, but no sound.

Output on device numer 3 worked with Wheezy.

Video output via HDMI on TV works, but no sound.

I had and have no customized alsa config files.

cat /proc/asound/card0/codec#0 | grep Codec
Codec: Realtek ALC892

I guess the problem due to Linux kernel change from 3.2 (Wheezy) to
3.16 (Jessie).

I tested HDMI sound output with the following two Live DVDs:

http://www.releases.ubuntu.com/14.10/ubuntu-14.10-desktop-amd64.iso
(Linux 3.16, MD5-Sum 08494b448aa5b1de963731c21344f803)

http://cdimage.debian.org/cdimage/archive/latest-oldstable-live/amd64/bt-hybrid/debian-live-7.8.0-amd64-xfce-desktop.iso.torrent
(Linux 3.2, MD5-Sum 99d1a12008b58bd4bfa7e6d3860cdc88)

Test result:
aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav
-> works on both Live DVDs (speaker sound)

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav
-> Ubuntu 14.10: Silence, as with Debian 8
-> Debian 7.8: works (HDMI sound on TV)

output of "aplay -l" was on both the same as above written.

No need to adjust alsamixer or anything, alsamixer looked good, no
mutes.

I think it's a bug is similar to
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=661335

Any suggestions how I can try to get the HDMI sound working again?
