[MPlayer-users] Problems emerged when playing audio with alsa (Mplayer 1.0rc2)

[dongbenson]

The mplayer vertion is 1.0.rc2, run on the arm9 board and kernel 2.6.18.The configure parameter is./configure --cc=arm-9tdmi-linux-gnu-gcc \--host-cc=gcc \--prefix=/work/src/mplayer/install/mplayer-1.0rc2/ \--enable-cross-compile \--target=arm-armv4l-linux \--disable-win32dll \--disable-dvdread \--disable-dvdnav \--disable-dvdread-internal \--disable-libdvdcss-internal \--enable-fbdev \--disable-mencoder \--disable-libmpeg2 \--disable-mp3lib \--enable-mad \--enable-static \--enable-alsa \--disable-gui \--disable-tv \--disable-live \--with-extraincdir=/opt/crosstool/gcc-3.4.1-glibc-2.3.3/arm-9tdmi-linux-gnu/arm-9tdmi-linux-gnu/include/ \--with-extralibdir=/opt/crosstool/gcc-3.4.1-glibc-2.3.3/arm-9tdmi-linux-gnu/arm-9tdmi-linux-gnu/lib/Another thing should be said was that I didn't install alsa-lib-dev before compiled mplayer because i couldn't find where to download it.But i used another way which seemed also work.I compiled alsa-lib static first,then the configure of mplayer could find the alsa well.But the problems emerged when playing audio with "-ao alsa" parameter using this way to compile the mplayer.The error log is as follows ./ # mplayer -ao alsa 1.wavMPlayer 1.0rc2-3.4.1 (C) 2000-2007 MPlayer TeamCPU: ARMPlaying 1.wav.Audio file file format detected.==========================================================================Opening audio decoder: [pcm] Uncompressed PCM audio decoderAUDIO: 44100 Hz, 2 ch, s16le, 1411.2 kbit/100.00% (ratio: 176400->176400)Selected audio codec: [pcm] afm: pcm (Uncompressed PCM)==========================================================================[AO_ALSA] alsa-lib: pcm.c:2145snd_pcm_open_noupdate) Unknown PCM default[AO_ALSA] Playback open error: No such file or directoryCould not open/initialize audio device -> no sound.Audio: no soundVideo: no videoIt could work well when used oss driver.The command was "mplayer -ao oss 1.wav".It seems alsa driver error ,but i couldnot make sure.How can solve this problem ? Do i need to config some files about alsa or mplayer?If someone knows ,please tell me .Any help would be much appreciated!Thanks in advance!Best Regards!dongas
