the workaround may be 1) remove index= 16 and skip_rest for HDA-Intel.pcm.iec958.0 2) change index $CTLINDEX to index 1 for HDA-Intel.pcm.hdmi.common ftp://download.nvidia.com/XFree86/gpu-hdmi-audio-document/gpu-hdmi-audio.html what you need to discuss with pulseaudio and alsa develoers are 12.5. Verify Your ELD Is Valid To validate that the ALSA driver is aware of your monitor, check the eld files. Recall that older chipsets (ION and earlier) don’t support ELD reporting, and hence the ELD files will not exist. In this case, ALSA always assumes that all audio features are available. For example, $ cat /proc/asound/card1/eld#3.0 monitor_present 1 eld_valid 1 monitor_name DELL U2410 connection_type HDMI eld_version [0x2] CEA-861D or below edid_version [0x3] CEA-861-B, C or D manufacture_id 0xac10 product_id 0xf016 port_id 0x40000 support_hdcp 0 support_ai 0 audio_sync_delay 0 speakers [0x1] FL/FR sad_count 1 sad0_coding_type [0x1] LPCM sad0_channels 2 sad0_rates [0xe0] 44100 48000 88200 sad0_bits [0xe0000] 16 20 24 For HDMI audio to work, both monitor_present and eld_valid must be 1. Furthermore, there will typically be evidence of at least some supported audio formats. -- 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
