I still can't use HDMI audio output. If I select Digital Stereo (IEC958) Output in Sound Preferences, no sound comes out. I have everything unmuted with alsamixer. My alsa version is 1.0.20+dfsg-1ubuntu5 and pulseaudio 1:0.9.19-0ubuntu4.1.
Any ideas? $ aplay -l && aplay -L **** Lista de Dispositivos PLAYBACK Hardware **** placa 0: Intel [HDA Intel], dispositivo 0: ALC663 Analog [ALC663 Analog] Dispositivo secundário: 1/1 Dispositivo secundário #0: subdevice #0 placa 0: Intel [HDA Intel], dispositivo 1: ALC663 Digital [ALC663 Digital] Dispositivo secundário: 0/1 Dispositivo secundário #0: subdevice #0 front:CARD=Intel,DEV=0 HDA Intel, ALC663 Analog Front speakers surround40:CARD=Intel,DEV=0 HDA Intel, ALC663 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=Intel,DEV=0 HDA Intel, ALC663 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Intel,DEV=0 HDA Intel, ALC663 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Intel,DEV=0 HDA Intel, ALC663 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Intel,DEV=0 HDA Intel, ALC663 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=Intel,DEV=0 HDA Intel, ALC663 Digital IEC958 (S/PDIF) Digital Audio Output null Discard all samples (playback) or generate zero samples (capture) pulse Playback/recording through the PulseAudio sound server $ lspci | grep Audio 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) -- digital audio optical out (IEC958) will not unmute/turn on https://bugs.launchpad.net/bugs/441746 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
