When starting an libsdl based application I always get the error: ALSA lib ../../../src/pcm/pcm.c:2106:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_pulse.so ALSA snd_pcm_open error: No such file or directory Audio Open Failed but "ls -la /usr/lib/alsa-lib/ | grep pulse" tells me it should be there: -rw-r--r-- 1 root root 30792 2007-02-05 12:15 libasound_module_ctl_pulse.a -rw-r--r-- 1 root root 968 2007-02-05 12:15 libasound_module_ctl_pulse.la -rw-r--r-- 1 root root 22264 2007-02-05 12:15 libasound_module_ctl_pulse.so -rw-r--r-- 1 root root 33588 2007-02-05 12:15 libasound_module_pcm_pulse.a -rw-r--r-- 1 root root 968 2007-02-05 12:15 libasound_module_pcm_pulse.la -rw-r--r-- 1 root root 23992 2007-02-05 12:15 libasound_module_pcm_pulse.so I'm using libsdl1.2debian-alsa on Ubuntu Feisty. I know there also is esd output package of sdl but esdcompat fails to start on all my Ubuntu systems. Thanks in advance. - sonium
