6. NVIDIA Hardware Architecture Different generations of GPUs contain different sets of codecs, converters, and pin widgets. The exact details are given below.
Early chipsets (ION an earlier) do not support PD or ELD information. In this case, the ALSA driver assumes that a monitor is always attached, and supports all audio features, including those which your monitor may not actually support. Newer chipsets and all GPUs support PD and ELD. you have to post the output of alsa-info.sh use chnmap to query the supported channel map http://git.alsa-project.org/?p=alsa-lib.git;a=blob_plain;f=test/chmap.c;h=d73ae7361498004f133f8ce5d9ee30f870baea1f;hb=HEAD t -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/881490 Title: Switched channels on HDMI 5.1 setup (Nvidia ION) Status in “pulseaudio” package in Ubuntu: Confirmed Bug description: I've choosen a Surround setup (HDMI 5.1) via sound preferences, and I got a problem. Some channels were inverted. I used the Hardware "Test speakers' to verify. The center sound was appearing on the rear-left, and so on... The only right channels were front-left and front-right. After search about this problem on the internet, I found this site: http://www.bunkerhollow.com/blogs/matt/archive/2011/06/18/zotac-nd22-xbmc-hdmi-audio-configuration-in-ubuntu-11-04.aspx The first weird thing is that the mentioned file, /usr/share/pulseaudio/alsa-mixer/profile-sets/nvidia.conf, doesn't exist on my machine, although I don't know if it were supposed to exist. After search for some similar file, I fixed the problem change the file /usr/share/pulseaudio/alsa-mixer/profile-sets/extra-hdmi.conf. I did what was suggested, commented the channel-map line and put a new one, as follows: ;channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe channel-map = front-left,front-right,front-center,lfe,rear-left,rear-right I'm reporting this because I think there is a way to detected the sound board and do it automatically. My board is: 00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1) Just let me know if you need more info!
