This is on a brand new 11.10 installation with:Īlsa.long_card_name = "Intel ICH5 with AD1985 at irq 17"ģ jacks at the back of the card to connect to speakers. If you require any addition info please do ask. I'm hoping I'm missing something really obvious and the solution is pretty straight forward. This last solution I was hoping would do the trick but when I list-sinks in pacmd the order seems to be the same all the time.Ĭhannel map: front-left,front-right,lfe,front-center,rear-left,rear-right In /usr/share/pulseaudio/alsa-mixer/profile-sets/ changed the channel map in nf for the 5.1 configuration - no joy. In /etc/pulse/nf changed system.pa and default.pa to not load the autodetect modules but instead use module-remap-sink as per - no joy. In order to do so I tried to use this command: ffmpeg -y -i input.mov -c:v libx264 -preset ultrafast -b:v 10000k -c:a libfdkaac -afterburner 1 -cutoff 20000 -filter:v 'scale-1:720' output.mp4. In /etc/pulse/daemon.pa changed sample channels to 6 (and also the default channel map) - no joy. Here's what I've tried so far (having searched A LOT): ffmpeg -i ' -c:v libx264 -preset ultrafast -crf 22 downloadedfile.mp4.

Trouble is only 2 of these are correct, the front-left and front-right. Stream parameters are 48000Hz, S16_LE, 6 channels Here's the output from speaker-test -c6 -l1 -twav: Here's what list-sinks in pacmd shows:Ĭhannel map: front-left,front-right,rear-left,rear-right,front-center,lfe So, I just need to change my channel map (correct me if I'm wrong on this). In my 5.1 configuration the wrong sound comes out of the wrong speaker. I've been struggling with this for a while now.Read up lots of posts, tried lots of solutions, no luck! My problem (in theory) is very simple.
