Hello! I was looking for some tests for the sound driver, and the only thing I found in ALSA CVS is some stuff in alsa-driver/test. Before I continue my search for real tests (any pointers will be appreciated!) let me post a patch that makes mmap_test.c compile and work.
First of all, mmap_test.c should be converted from DOS to UNIX-style line ends before my patch is applied. There is no "smpl" file in the alsa-driver/test directory, but we can easily generate a sample. sin() requires libm, hence the makefile change. The necessary includes have been added to avoid warnings. Unused variables have been removed for the same reason. If the "smpl" file cannot be loaded, a sound of variable frequency is generated. SNDCTL_DSP_SETPERIOD is undefined (google search gives 0 hits, I wonder if this code ever compiled), but SNDCTL_DSP_SETFRAGMENT seems to do exactly what we need. info.periods has been replaced with info.fragsize for the same reason. Now mmap_test compiles without warnings and produces funky sounds.
