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
