Judging from the logs, alsainfos etc, I'd say we can nail down this bug to somewhere in alsa-lib, if this is working:
speaker-test -D plughw:NVidia,3 -c 2 -t wav And this is not working: speaker-test -D hdmi:NVidia -c 2 -t wav As a temporary workaround, you can edit /usr/share/pulseaudio/alsa-mixer /profile-sets/extra-hdmi.conf and replace every "hdmi:%f" with "hw:%f,3" and see if that helps. (Restart pulseaudio for changes to take effect, e g by rebooting your computer.) But this does not explain your error "pcm.c: Unknown PCM hdmi:0". Is it possible that either of the files /usr/share/alsa/pcm/hdmi.conf or /usr/share/alsa/cards/HDA-Intel.conf have become corrupted? To restore them to the original I believe "sudo apt-get install libasound2-data --reinstall" would do the trick. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249705 Title: HDMI output not available in 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1249705/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
