asterisk users - Nov 2003 - problems with alsa (card ac97) in asterisk

Hello,

I have asterisk 0.5.0, asterisk-oh323-0.5.6, openh323-1.12.2 and pwlib 1.5.2 
compiled and installed.
I have modules alsa 0.9.8 compiled and installed
My PC have and audio card ac97 chipset intel i810 in motherboard.

The list of the modules loaded is:
namor:/etc/asterisk# lsmod
Module ? ? ? ? ? ? ? ? ?Size ?Used by ? ?Not tainted
snd-pcm-oss ? ? ? ? ? ?35652 ? 0
snd-mixer-oss ? ? ? ? ?11264 ? 1 ?[snd-pcm-oss]

snd-ac97-codec snd-pcm snd-timer snd-mpu401-uart snd-rawmidi snd-seq-device]

Another program working well with modules alsa (mplayer or xmms)

If I run asterisk -vvvc, the program abort for module chan_alsa.so

?[chan_modem.so] => (Generic Voice Modem Driver)
? == Parsing '/etc/asterisk/modem.conf': Found
? == Loading modem driver chan_modem_aopen.so => (A/Open (Rockwell Chipset)

?[chan_alsa.so] => (ALSA Console Channel Driver)
asterisk: pcm.c:5486: snd_pcm_sw_params_set_silence_threshold: Assertion `val 
<?pcm->buffer_size' failed.Aborted

There is problems between asterisk and alsa or ac97 ?
I need any option for to compiler asterisk ?

Thank

I guess most people prefer to use oss rather than alsa...? this issue 
was noticed earlier this year, and the fix is now included in cvs:
http://bugs.digium.com/bug_view_page.php?bug_id=0000526

I am also using i8x0 and alsa, and this patch (or latest cvs) works 
great for me.

cheers
