Octo with Logitech Media Server 4 channel

Post by theloon » Tue May 02, 2017 2:47 am

:? Anyone know what settings to use to get 4/8 channel output with LMS? I have it working fine with 2 channel stereo but would like it to output to all speaker outputs. :D

Can you link me to the software, perhaps I can have a look at their information ?

thanks

Hi Matt, nice sound card by the way!
Here's the link to one of the tutorials, http://www.gerrelt.nl/RaspberryPi/wordp ... r-for-bbq/. I wrote a script to automate everything for installing on Jessie lite after installing pixel for a slimmed down version and would like to have all Octo's outputs working in the process. Once things have been ironed out I'll be spreading the news to other audiophiles, Thanks!
Here is something that may interest you. http://www.hotto.de/software/quadrophon ... coder.html

You could create an ALSA plugin which would route stereo to speaker pairs ... something like this (which routes channels 0 and 1 in pairs to all other channels) :

Code: Select all

pcm.!default {
        type hw
        slave.pcm "repeatStereo"
}

ctl.!default {
        type hw
        card 0
}

pcm.repeatStereo {
    type route
    slave.pcm "hw:0"
    slave.channels 8;
    ttable {
           0.0 1
           1.1 1
           0.2 1
           1.3 1
           0.4 1
           1.5 1
           0.6 1
           1.7 1
    }
}

ctl.repeatStereo {
    type hw;
    card 0;
}
