Hello, I'am new for using ALSA API. I was astonished that a simple wav playback example does not exist. But after reading the pcm examples I have managed to make one (if I will finish it I can post it so it can be added to the examples) Now my question: What should be used: snd_pcm_mmap_commit <http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m___direct.html#g3e3d8bb878f70e94a746d17410e93273> (I think snd_pcm_mmap_writei <http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m___direct.html#g3a811efcd9d64b60e6a25df6924d26b0> is the same with an additional copy behind ?) or snd_pcm_writei <http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m.html#gf13067c0ebde29118ca05af76e5b17a9> I think mmap will have better performance, but will it work with all soundcards? Or should it be in a config what to use? I'am also looking for a function to get the number of played frames. I have played around with "snd_pcm_status" but it seems not to have a counter for this. By the way is there a detailed tutorial (introduction) for ALSA available? The online help is a little bit too short for newbies. ;-) Reiner _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
