No voices with MKV videos

[EMK0]

I installed Rev18098 and now the MKV videos i cant hear any one talking anymore, but i can hear the sound effects. I think this has to do something with the 5.1 sound i don't have 5.1 i just use the analog speakers on my TV. The XVID files the audio works fine and they don't have 5.1 sound. I posted a ticket on the tracker with my debug log http://xbmc.org/trac/ticket/5990. The sound worked fine on my previews install which was rev18004.

found some error in the log

DEBUG: Error: Requested setting (audiooutput.downmixmultichannel) was not found. It must be case-sensitive
DEBUG: CDVDPlayerAudio:: Discontinuty - was:77307000.000000, should be:77272500.002086, error:-34499.997914

in my guisettings

<audiooutput>
<ac3passthrough>true</ac3passthrough>
<audiodevice>Default</audiodevice>
<dtspassthrough>true</dtspassthrough>
<mode>0</mode>
</audiooutput>

is there something missing or wrong?

How exactly are you getting sound from XBMC to the TV? You should not have dolby or dts passthrough enabled if you aren't connected to a device that can decode them.

when i go to my sounds option i have it set at analog just like before i installed this rev. When i choose analog i can not touch those ac3 dts stuff. Should these be false and if so how did they become true if i didn't touch that?

I think more info about your hardware setup might be helpful.

[EMK0]

from what i understand even if those are set to true they wont work until you set them to digitial. I changed them to false anyways and it still doesn't have sound for voices.

I not 100% sure on my hardware
its something like Amd x2 2.4gigz
2gigs of ram
nvidia on board graphics card with HDMI
i use the HDMI to hook up to my tv and i can only use NVIDIAs audio.

if you guys need exact info please tell me i will have to go get it later though.

All this worked fine on previews build and i did not change anything since the previous build except delete the guisettings because they where causing a problem.

i updated to build 18141 still the same no voices in MKV movies i also found that xvid videos with ac3 did the same thing. Am i the only one who is getting this problem?

[EMK0]

This is very strange i finally go it to work by setting it to digital in the OSD before if i set the audio to digital i would get no sound at all now it works and the analog doesn't work correctly.

[EMK0]

OK i found the only settings what will make the sound work with voices but i am not sure why it works like this i am just using the TV speakers i have no dolby or dts thing just 2 speakers from the TV. Anyways

i must set the audio to digital and enable ac3 pass through

<audiooutput>
<ac3passthrough>true</ac3passthrough>
<audiodevice>Default</audiodevice>
<dtspassthrough>false</dtspassthrough>
<mode>1</mode>
</audiooutput>

anyways this works fine :cool:

ok i found something interesting here http://xbmc.org/trac/changeset/18029 from what i can see there should be a gui setting downmixmultichannel in the guisettings . I deleted the guisettings i currently have and reloaded xbmc and still there is no setting like this i will try to add it and see what happens.

Hi.

First post.
I also had this issue with newer builds.
Today i downgraded to 8.10 (official build) and it all works fine "out of the box".
Plain Samsung LCD tv - no reciever - two speaker setup.

I have the same issue

[mattb]

I believe I have the same problem. I updated from rev17735 to rev18257, and now 5.1 AC3 tracks don't seem to be downmixed to analog 2 channel properly. Things "just worked" out of the box before, now the audio mixing is all wonky, and it seems like the center channel isn't even mixed (resulting in voices being mostly omitted or far too low in volume). Using analog audio over HDMI.
