[Asterisk-Dev] chan_alsa broken ?

Hi folks,
  this is going to seem dumb - apologies in advance, but...

Has anyone managed to get chan_alsa to work with version 0.9.5 or 
0.9.6 of alsa?
I've installed alsa on a RH9 box with support for the cheapo card I 
have (CMIPCI)
and it works fine, but it bombs with *.

This seems to be an issue on line 426 of chan_alsa.c
I fixed it by putting back in:
	err = snd_pcm_sw_params_set_silence_threshold(handle, 
swparams, buffer_size/2);
that used to be there rather than the:
	err = snd_pcm_sw_params_set_silence_threshold(handle, 
swparams, buffer_size);
which seems to have drifted into the * distribution.

Am I missing something, here?

Even with this tweak, I still can't get alsa+card to record sounds in 
* (plays out
fine in *, and records/plays using arecord/aplay), but that's a 
problem for tomorrow.

all the best,
   Lawrence
