the driver did not create the controls at index=0 the control create controls at index=0 only if the driver load MCP73 codec first before alc888
alc888 seem alway load before MCP73 , so those iec958 controls with- index=0 are created at device 1 (spdif) and those IEC958 controls with index=1 at device 1 (HDMI) http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=ea9b43addc4d90ca5b029f47f85ca152320a1e8d HDMI devices will be put to dev=0,index=0 as before. you have to send email to the author of the patch about your case which HDMI device does not have those IEC958 controls at index=0 Node 0x04 [Audio Output] wcaps 0x211: Stereo Digital Control: name="IEC958 Playback Con Mask", index=1, device=0 Control: name="IEC958 Playback Pro Mask", index=1, device=0 Control: name="IEC958 Playback Default", index=1, device=0 Control: name="IEC958 Playback Switch", index=1, device=0 Device: name="HDMI 0", type="HDMI", device=3 Converter: stream=0, channel=0 Digital: Enabled Digital category: 0x0 IEC Coding Type: 0x0 PCM: rates [0x40]: 48000 bits [0x2]: 16 formats [0x1]: PCM Node 0x05 [Pin Complex] wcaps 0x400381: Stereo Digital Control: name="HDMI/DP,pcm=3 Phantom Jack", index=0, device=0 Pincap 0x00000014: OUT Detect Pin Default 0x185601f0: [Jack] Digital Out at Int HDMI Conn = Digital, Color = Unknown DefAssociation = 0xf, Sequence = 0x0 Misc = NO_PRESENCE Pin-ctls: 0x40: OUT Unsolicited: tag=00, enabled=0 Connection: 1 0x04 http://git.alsa-project.org/?p=alsa- lib.git;a=blob_plain;f=src/conf/pcm/hdmi.conf;hb=HEAD -- 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
