your alc888 have two digital outs the previous implementation The multiple outputs are handled as slave streams, so only one PCM stream (and the corresponding IEC958* elements) is provided to control both digital outputs. HDMI - OK (simultaneously with S/PDIF) S/PDIF - OK (simultaneously with HDMI) https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/Documentation/sound/alsa/HD-Audio.txt e.g. you can use hint indep_hp=1 by early patching to crdate the alt analog device 2 for the headphone https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=9a08160bdbe3148a405f72798f76e2a5d30bd243 When "IEC958 Default PCM" switch is on, the PCM stream is routed both to analog and SPDIF outputs. sound is routed to analog, spdif and hdmi in your case https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=ccfcf7d151c01969133b5555eed635537c41c944 those HDMI 1.3 support Jack detection graphic driver get HDMI TV 's EDID and pass ELD to audio driver https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=1613d6b46b433f07f1d2703e4bd102802dcd75a4 https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=ea9b43addc4d90ca5b029f47f85ca152320a1e8d you have to ask tiwai how to solve your case by providing the working and non working alsa-info it is possible to split into two digital devices 1 and 3 so that you can play different audio to HDMI and S/PDIF if the hda controller support four SDO playback streams but will lost the capabitiy of playing audio to HDMI and spdif -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1247160 Title: Ubuntu 13.10 [Studio Hybrid 140g, Realtek ALC888, Black Digital Out, HDMI] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1247160/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
