Dear all: Is there simple program which can help me to play and capture pcm files from usb speaker and mic? appreciate your help, miloody
aplay, arecord
I found them in alsa-utility :) but when I try to configure them, I get following messages:
checking for form.h... yes checking for new_panel in -lpanelw... no configure: error: panelw library not found
but I list the /usr/lib, I see $ ls /usr/lib/libpanel* -lht lrwxrwxrwx 1 root root 27 2009-11-11 07:59 /usr/lib/libpanel-applet-2.so.0 -> libpanel-applet-2.so.0.2.60 lrwxrwxrwx 1 root root 16 2009-11-11 07:52 /usr/lib/libpanelw.so.5 -> libpanelw.so.5.7 lrwxrwxrwx 1 root root 15 2009-11-11 07:52 /usr/lib/libpanel.so.5 -> libpanel.so.5.7 lrwxrwxrwx 1 root root 13 2009-11-11 00:41 /usr/lib/libpanel.so -> libpanel.so.5 -rw-r--r-- 1 root root 51K 2009-10-19 22:00 /usr/lib/libpanel-applet-2.so.0.2.60 -rw-r--r-- 1 root root 19K 2009-10-12 21:12 /usr/lib/libpanel.a -rw-r--r-- 1 root root 14K 2009-10-12 21:12 /usr/lib/libpanel.so.5.7 -rw-r--r-- 1 root root 14K 2009-10-12 21:12 /usr/lib/libpanelw.so.5.7 $
did I miss something? I try to run the aplay/arecord under console and if I guess correctly, I don't need panelw lib. if so, how could I disable it? appreciate your help, miloody
what is panelw
Those are ncurses libs required by alsamixer. Try
./configure --disable-alsamixer --disable-alsaconf
That has worked for me, ubuntu 9.10.
I can compile it under ubuntu right now.
I list some questions about alsa: 1. when I try to cross-cmpile alsa-lib-1.0.23, it cmplain aserver.o: In function `pcm_shm_cmd': aserver.c:(.text+0x1f08): warning: Warning: snd_pcm_hwsync() is deprecated, consider to use snd_pcm_avail() ../src/.libs/libasound.so: undefined reference to `atomic_sub' ../src/.libs/libasound.so: undefined reference to `atomic_add' collect2: ld returned 1 exit status make[1]: *** [aserver] Error 1
and I find the atomic_sub is define in include/iatomic.h which is implemented by different kind of arch. the host I set is mipsel-linux and I see -D__mips__ appears when I cross-compile the source. And atomic_sub should be found already, but why it still complain not finding the function?
2. what nodes should I build under /dev when I try to run the alsa-util?
3. is there any tool I can generate raw, pcm, data such that I can apay it?
appreciate your help, miloody
