<div class="moz-cite-prefix">Adding to the subject :<br>
I found on the web and in the source code of HDSPMixer 2
interesting things, namely:<br>
- despite the effective 3x16 channels, it seems the internal
channels might be 3x64, or at least 64 inputs, 64 outputs and ???
playback channels<br>
- the source code shows a <span class="code">"playbacks_offset</span>
= 64" variable<br>
I don't really see how to use these news as the code below doesn't
work. (reminder : the goal is to connect playback channels 1&2
to outputs 7&8)<br>
<br>
function set_gain () { amixer -c hw:0 cset numid=1 $1,$2,$3 >
/dev/null 2>&1 }<br>
function reset_matrix () {<br>
for out in $(seq 0 63); do<br>
for inp in $(seq 0 63); do<br>
set_gain $inp $out 0<br>
done<br>
done }<br>
reset_matrix<br>
#following lines tried 2 by 2 :<br>
set_gain 0 6 65535 #doesn't work (I tried 0 and 1 inputs as
there is sound there in graphical HDSPMixer vu-meter)<br>
set_gain 1 7 65535 #doesn't work<br>
set_gain 64 6 65535 #doesn't work (64 and 65 as 1st playback
channels)<br>
set_gain 65 7 65535 #doesn't work<br>
set_gain 0 128 65535 #doesn't work<br>
set_gain 1 129 65535 #doesn't work<br>
set_gain 64 128 65535 #doesn't work<br>
set_gain 65 129 65535 #doesn't work<br>
exit 0<br>
<br>
Any idea ?<br>
