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
