A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2287> ====================================================================== Reported By: cruiseoveride Assigned To: ====================================================================== Project: ALSA - lib Issue ID: 2287 Category: 0_general Reproducibility: always Severity: crash Priority: normal Status: new ====================================================================== Date Submitted: 07-16-2006 18:03 CEST Last Modified: 07-19-2006 03:27 CEST ====================================================================== Summary: Segfaults all functions after snd_pcm_hw_params_get_buffer_size (params,(snd_pcm_uframes_t *) & val); Description: I am new to Alsa and am not happy at all at the state of documentation available. You guys seriously need to do something about this. I have an M-Audio Audiophile Delta 192 (ICE1724) and I want to port envy24control for this chip, However I first need to familiar myself with the ALSA API. So I began by looking for simple examples on how to use ALSA API and came accross the followinf prog (Attached file test.c). The program compiles cleanly with gcc-4.1 and runs, however after it prints out the ..."buffer size = 8192 frames" It segfaults. If you slash out line 104, it resolves the issue. My question is, Is there a bug in this function? Code was obtained from http://www.linuxjournal.com/article/6735 ====================================================================== ---------------------------------------------------------------------- cruiseoveride - 07-19-06 02:52 ---------------------------------------------------------------------- its great that ur helping me ray, but eash post i ask u at least 3 different things, u only seem to see the last one in each case...
