hello,
tested successfully with a HDSP 9652.
great usefull tool !
notice that if hdspmixer has not been started after bootup (means the card
is not initialized in some way), hdspdump throw no error, and creates a
dump file filled with 0. It means that alsa is not throwing errors either
as your programs goes nicely to the end.
I've been looking at hdspmixer code for some days now to make it console
only, removing FLTK dependencies. Your program gives me motivation to go on
with this hard task.
i have no idea what a "console-only" version of hdspmixer would actually
do, but perhaps you could consider the following as inspiration also (which
uses amixer(1) to control the hdsp matrix mixer from the cmd line):
#!/bin/bash
AMIXER="amixer -q"
CARD="-c 1"
if [ x$1 = xon ] ; then
gain=32768
verb="route"
else
gain=0
verb="mute"
fi
shift;
#input_source : 0-25 (physical channels),
# 26-51 (software playback)
#output_source : 0-25 (physical channels),
# 26-27 (line out)
