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 started off by copying the ice1724.c as ap192k.c
then followed
http://www.alsa-project.org/~iwai/writing-an-alsa-driver/x1658.htm
but i still get a "No Rule to Make Target" during a compile.
How do i properly add the driver to alsa-driver
i have 2 files
/usr/src/alsa/alsa-driver-1.0.12rc1/alsa-kernel/pci/ice1712/ap192k.c
/usr/src/alsa/alsa-driver-1.0.12rc1/alsa-kernel/pci/ice1712/ap192k.h
and by the way rlrevell, if ALSA is supposed to be the "Advanced Linux
Sound Architecture" then it should be a very very long book.

Refer to the Function Block Diagram
http://www.via.com.tw/en/products/audio/controllers/envy24ht/
The current alsa driver ice1724.c support differenct sound cards by
checking PCI SUBSYSTEM Vendor and Device ID and enable the corresponding
features of the iec1724 chip.
What you need to do is to implement the ap192 card specific low level
routines in ap192.c and add snd_vt1724_ap192_cards in ice1724.c
static struct snd_ice1712_card_info *card_tables[] __devinitdata = {
snd_vt1724_revo_cards,
snd_vt1724_amp_cards,
snd_vt1724_aureon_cards,
snd_vt1720_mobo_cards,
snd_vt1720_pontis_cards,
snd_vt1724_prodigy192_cards,
snd_vt1724_juli_cards,
snd_vt1724_phase_cards,
+ snd_vt1724_ap192_cards,
NULL,
};
