If you let me I set this as wontfix. Anyway i'm going to attach in another bug I opened a way to have in pulseaudio options like graphical channel remaping and multiple output without doing it in text and without the need of profiles but this in the other one. -- Ticket URL: http://pulseaudio.org/ticket/626#comment:8 PulseAudio http://pulseaudio.org/ The PulseAudio Sound Server ___ pulseaudio-tickets mailing list pulseaudio-tickets@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-tickets

Comment(by howl):
Sorry I writed the code wrong:
{{{
[Mapping hdmi-surround-71]
description = Digital Surround 7.1 (HDMI)
device-strings = hdmi:%f
channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe
,side-left,side-right
priority = 6
direction = output
}}}
I put the description to match the other outputs because without it in the
profile selector hdmi-surround-71 is shown instead.

#626: Some nvidia hdmis now supports more than 2 channels -+-- Reporter: howl| Owner: lennart Type: defect | Status: new Milestone: | Component: module-alsa-* Resolution: |Keywords: -+-- Comment(by lennart): For analog, ALSA provides device strings like surround51:xx which can be used to imply a very specific channel order. However, there is only one hdmi: device string which does not imply any channel order. HDMI on the hw level is very flexible in the selection of channel maps. For every number of channels it supports a number of different number of maps -- which is negotiated between the PC and the hdmi receiver. If we'd add a 'default' mapping for multichannel here then this might work for you, but won't work people with dfferent hardware. To support this properly we need to wait until ALSA introduces a proper channel map negotiation API, or at least hdmi device strings that imply a channel order (i.e. 'hdmi-surround51:' or something like that. But it doesn't do that right now. -- Ticket URL: http://pulseaudio.org/ticket/626#comment:7 PulseAudio http://pulseaudio.org/ The PulseAudio Sound Server ___ pulseaudio-tickets mailing list pulseaudio-tickets@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-tickets

#626: Some nvidia hdmis now supports more than 2 channels +--- Reporter: howl| Owner: lennart Type: defect | Status: new Milestone: | Component: module-hal-detect Keywords: | +--- Not sure if this must go here or to alsa. In kernel 2.6.31-rc1 tag a patch to support 8 channels hdmi found on some recent nvidia gpus was merged. I have been messing arround with pulseaudio 0.9.16 and when using autodetection the hdmi is shown as stereo only, also specifying 8 channels default in pulseaudio config. This is shown in the first screenshot. When setting manually alsa-source module with hdmi:0 then pulseaudio shows the 8 channels but with a wrong mapping. This is shown in the second screenshot. Setting 10 channels default in the pulseaudio config the correct mapping is shown, Front left, front right, Rear left, Rear right, Center and LFE. -- Ticket URL: http://pulseaudio.org/ticket/626 PulseAudio http://pulseaudio.org/ The PulseAudio Sound Server ___ pulseaudio-tickets mailing list pulseaudio-tickets@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-tickets

Could be a way to test or to ask how many channels a device can have at max. -- Ticket URL: http://pulseaudio.org/ticket/626#comment:3 PulseAudio http://pulseaudio.org/ The PulseAudio Sound Server ___ pulseaudio-tickets mailing list pulseaudio-tickets@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-tickets
