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

ok i did that.

WilL ALSA write the new drivers or am i on my own. Can't return the card
already returned the X-Fi .

I am only an ALSA user with Vortex 2 au8830 sound card. 

Why don't you help other to port envy24control ?

During the communication with the other ice17xx users, this may allow you
to learn 
1) difference between 1712 and 1724
2) difference between vt1721 and vt1724
3) difference between juli@ and Audiophile 192

If you can hack envy24control to monitor the Main RCA OUT Line, this means
some registers are common to 1712 and 1724.

Modify envy24control.c to identify driver is 1712 and 1724 , 

Read 1724 EEPROM and identify different 1724 cards, different features on
juli@ and Audiophile 192
