+Summary: alsasink gives error with snd-via82xx
+
+ALSA version 0.9.7
+ With my snd-via82xx driver, the alsasink plugin doesn't work.  It fails here :
+  ret = snd_pcm_sw_params (this->handle, sw_param);
+
+The error given is:
+ALSA lib pcm_hw.c:370:(snd_pcm_hw_sw_params) SNDRV_PCM_IOCTL_SW_PARAMS
+failed: Invalid argument
+
+  I discovered that the error appears only if the silence size sw property
+is set.  I uncommented this block to make it work:
+
+  ret = snd_pcm_sw_params_set_silence_size (this->handle, sw_param,
+this->buffer_frames);
+  if (ret < 0) {
+    g_warning ("could not set silence size: %s", snd_strerror (ret));
+    return FALSE;
+  }
+
+  Setting the parameter to zero also works.
+
+  I am not claiming it's gstreamer's fault, because I simply do not know. 
+What do you think?
