alsa-devel，你好：
I am new to ALSA, now I try to add one sound soc chip in linux 2.6.21 kernel on samsung arm designed board.
I have do some underside work:
1: I have porting linux 2.6.21 kernel on samsung arm designed board.(log.txt add accessories)
2. kernel have recognise sound chip form log information.
3. I have a test app working in linux 2.6.18.(this test app is tested ok!)
4. I have download "alsa-lib-1.0.15.tar.bz2" and buid in linux host(Linux 2.6.18-5-686 #1 SMP Fri Jun 1 00:47:00 UTC 2007),create libasound.so.2.0.0.
build order:
1)./configure --host=arm-linux CC=arm-linux-gcc ( i do not affirm this config)
2) make
3) and then change to su to use to make install.
5. download libasound.so.2.0.0 lib to samsung designed board and download test app to samsung designed board.
6. but i run test ,system prompt err:
ALSA lib pcm.c:2143:(snd_pcm_open_noupdate) Unknown PCM default
Playback open error: No such file or directory
Segmentation fault
now,I doubt libasound.so.2.0.0 lib is conflict with kernel 2.6.21. hope help .
