--- Comment #54 from Chris chris.kcat@gmail.com 2010-05-07 19:57:11 --- snd_pcm_sw_params_set_silence_threshold is an ALSA function. There's nothing particularly special about it that I know of, though, so I can only imagine that the two games are overwriting heap memory a bit differently. You need to figure out what's causing the memory to be overwritten and why; the ALSA crashes are just a side-effect of the issue.
