Hello again Raymond and whoever is following this report, I replaced the HDA-Intel.conf with the above(see #45). My results are the same. Audio-test -c 6 -t wav results in audio out via the HDMI, stereo only. Left-Right reversed and Left-Right Rear, Center and LFE barely audible. Audio test videos can be obtained at http://www.dolby.com/us/en/consumer/technology/home-theater/dolby-digital-plus-download.html I have also been using some test DVDs I purchased while working in the production studios. The DVD set is called "Video Essentials NTSC" test dvds by JKP.
Running a test using XBMC settings as follows: Top selection: Audio Output --> HDMI Speaker Configuation --> 5.1 Lower Section: Audio Output Device --> HDA NVidia, HDMI Passthrough Device --> HDA Nvidia, HDMI These settings result in only digital data in the audio output (Buzz or Hiss). Top section (as above) Lower Section: Audio Output Device --> HDA Nvidia, ALC888 Digital S/PDIF Passthrough Device --> HDA Nvidia,ALC888 Digital S/PDIF These settings result in decoded audio playback of 5.1 surround sound using these encoded test videos. Video: 1920x1080 H.264 @ 24 fps (all test videos) Test video #1: Audio Codec: E-AC-3 (ATSC A/52B) Channels: Surround 5.1 Sample Rate: 48000 Hz Bitrate 640 kbps Test video #2: Audio Codec: DolbyTrueHD Channels: Surround 7.1 Sample Rate: 48000 Bitrate N/A Using the surround sound test video "channelcheck-large.mp4" or "channelcheck-small.mp4". File with extention .m2ts produces digital noise output in VLC. VLC media player version "2.0.9 Twoflower" settings: HDA Nvidia, HDMI 0 Audio out selected produces only 5.1 downmixed to stereo. There is no option for surround sound with this selection. The 5.1 downmix to stereo is also not properly a mapped L-R it is reversed as R-L. All HDMI 0 selections available to play through HDMI is only Stereo, there are no 5.1 surround sound options under Audio Channels dropdown or Audio Device dropdown except analog. HDA Nvidia, ALC888 Digital IEC958 (S/PDIF) Digital Audio Output only produces Stereo only. Using the Audio Selection of: Playback/recording Through Pulseaudio Sound Server, produces audio out receiver selected input S/PDIF or HDMI with Pulseaudio selections (IEC958) or (HDMI) in Stereo only. Summery of my findings with both ALSA and Pulseaudio, with the above HDA-Intel.conf and even the original script are as follows: 1. The original script was limited to selections for audio output. An additional output that I have noticed was the "Playback/recording Through Pulseaudio sound server", something I have never noticed before. 2. All output selections only produce Stereo output. There is no selection for 5.1surround either S/PDIF, IEC958 or HDMI. There is only Analog 5.1 and above available. Earlier releases of Ubuntu before 13.10 had options for 5.1surround S/PDIF, IEC958 or HDMI in the Audio Output selection and Audio Channels of VLC. I have not tested with earlier versions of VLC. 3. When testing under XBMC version Frodo 12.2, I have full Digital 5.1 surround sound via S/PDIF receiver selection. When selecting direct HDMI on the receiver, not HDMI-auto which will default to S/PDIF, some of the video's audio track did not play through HDMI or if an encoded 5.1 track were to play the audio there is only digital buzz or hiss. 4. Here is something to look at. Why is XBMC producing 5.1 surround sound via S/PDIF when VLC or other media players do not? Most all experienced users of XBMC state; turn off or completely remove Pulseaudio. I feel that it is not Pulseaudio and or ALSA that is thes issues since there is no 5.1surround in the standard media players and there is 5.1 surround in XBMC but only via S/PDIF. 5. Lastly, then I am done here with this since there is no discussion on a once and for all fix not patches for this. As I have stated before more then once, I feel that it is about time to have the developers get away from two packages for audio. Also, get out of the possible mindset of "if it is not broke, then don't fix it" As a Broadcast Engineer, I have found that sometimes it may be easier to work with what you have and just keep patching. In this case it is broke, now it is time to fix it once and for all. Scrap these two troublesome packages and develop something new. One Package not another combine this or patch that combination. Make the package as an option in a update or a stand alone option to install. Lets say one is developed, the user installs it via a package handler or via the terminal, it uninstalls ALSA and Pulse from the system then installs the new audio package.. I know that this is easier said then done, but this issue has gone on for years. So lets start on something and table any fixes or patches for what is there now so there is time for new development. What most have forgotten here is that the everyday user; not someone like me that can grasp most of the infomation above, is not going to understand any of what has transpired within all these posts. Ubuntu is showing up more and more in many consumer products and especially Home Theater systems in one form or another. It is a Plug n` Play world whether it is Linux or Microsoft. Having to jump through hoops to set up the audio is not going to slide by the user much longer when using this distro or any distro using ALSA and Pulseaudio. Over the years things have changed in this distro for the better as in speed and efficiency. By my experience using this distro especially this released version 13.10, it seems the audio has not advanced, but is actually degrading and falling behind technology. So I can finally enjoy my Home Theater System here, I have retired to using just the 5.1 S/PDIF output for XBMC and just deal with stereo output for all the other media players. I would suggest to keep this bug report open until there is a final decision what is going to be done with this ongoing audio issue. -- 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
