hi,
problem 1:
i am using alsa driver for my ES 1938 sound card. soundcard supports full duplex. I
got a program for full duplex "pcm.c" from alsa lib 0.5.1 package.but i m using alsa
0.9.1 package. When i executed the program typing gcc -o pcm.out pcm.c -lasound it
gave some error which reads like this:
in file included from /usr/include/sound/pcm.h:27
from pcm.c:4:
/usr/include/sound/memalloc.h:181:41 missing binary operator before '>='
is this error related to the alsa package version? or is there any way to execute it?
problem 2:
do i need to give "alsamixer" command and make adjustments for mic and playbak? i
am asking b'coz when i set all these to 100% i can her what i speak with out my
program running. Do i really need to do this prior to running my program? i am in
confusion .
please help,
thank you,
mahendra
