#626: Some nvidia hdmis now supports more than 2 channels --+- Reporter: howl | Owner: lennart Type: defect | Status: closed Milestone: | Component: module-alsa-* Resolution: wontfix |Keywords: --+- Changes (by howl): * status: new = closed * resolution: = wontfix Comment: Thanks for the explanation with surround51:x I knew this type of devices output but didn't see the implication in the channel mapping. 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

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
