Not all soluble fiber is gassy. It depends on the fermentation rate of the soluble fiber. For example inulin which is used as a soluble fiber supplement rapidly fermented causing problems for many IBS suffers. Other soluble fibers like guar gum and wheat dextrin are slower fermenting. However, you could try products that contain methylcellulose and polycarbophil such as FiberCon and Citrucel which are non-fermentable soluble fiber supplements making them less likely to cause intestinal gas.

You might check the FODMAP diet discussed in the first two links of my signature. This diet is designed specifically to reduce the consumption of foods that contain ingredients that can be malabsorbed in the small intestine but easily fermented in the large intestine to produce gas.
