Trying to reduce my left and right channels to 0.5, but am noticing ALSA is
only reading values specified as floating as "0". (Tried the old syntax as
well.)
So ttable only see integer (INT) values for the third field now? Either 0 or 1
only?
The below should reduce the volume slightly on channels left (0) and right (0),
but it's obvious I'm getting the channel set to zero (0) or off.
(The following ensure PCM 5.1 streams are streamed through HDMI to a 5.1 stereo
receiver properly. A profile is desired for PCM 5.1 music streams having weak
center and rear channels. So reduce left and right channels to 0.8 or further
to 0.5, or half.)
File ${HOME}/.asounrc:
pcm.myHDMI {
type route slave {
pcm "hw:1,7"
format S32_LE
channels 6 }
ttable {
0.0= 0.9
1.1= 0.9
2.4= 1
3.5= 1
4.2= 1
5.3= 1
}
}
OR
File ${HOME}/.asounrc:
pcm.myHDMIX {
type route slave {
pcm "hw:1,7"
format S32_LE
channels 6 }
ttable.0.0 0.9;
ttable.1.1 0.9;
ttable.2.4 1;
ttable.3.5 1;
ttable.4.2 1;
ttable.5.3 1;
}
