I guess your idea was to include a goto finish; right before the problematic code with snd_pcm_hw_params_set_periods_near() by commenting the 'if ((ret = snd_pcm_hw_params_set_periods_integer(pcm_handle, hwparams)) < 0)' line? In that case pulseaudio starts up, but doesn't set up any PCM's. Jan 20 00:12:21 negr pulseaudio[11755]: (alsa-lib)pcm.c: PCM not set up So there's nowhere to send the playback, no devices except the Null Output device are shown in the pulse volume control. However I also tried commenting out the snd_pcm_hw_params_set_periods_near() function calls. Thanks to this my USB sound card popped up in the pulse audio volume control. My integrated nvidia chip worked. I could send the output stream to the usb card, though no sound would come out nor would the sliders move to indicate playback. Though that didn't crash anything and I could transfer the stream back to the built in sound chip which works. But when tried changing the volume of the USB card, pulseaudio crashed. I did all of this in pavucontrol.
