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: http://pastebin.com/NeCBZxJt aplay -l **** Liste der Hardware-Geräte (PLAYBACK) **** Karte 0: PCH [HDA Intel PCH], Gerät 0: ALC892 Analog [ALC892 Analog] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 0: PCH [HDA Intel PCH], Gerät 1: ALC892 Digital [ALC892 Digital] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 0: PCH [HDA Intel PCH], Gerät 3: HDMI 0 [HDMI 0] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 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 (forwarded to https://bugzilla.kernel.org/show_bug.cgi?id=42955) Any suggestions how I can try to get the HDMI sound working again? -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
