The only fix that I have found so far was to replace the sounds and the sound gauge file that came with the product with a free one from the avsim file library. Unfortunatly, that file library is offline and has been since avsim was hacked. If anybody has those files, please let us know.

Others have submitted support tickets for this same issue and they were told that this was going to be resolved in the next service pack which has no ETA to my knowledge and some of those posts are almost a year old.

The sound issue is really the only complaint that I have. The airplane itself is absolutely fantastic with a great VC, lots of systems to play with and this aircraft is my new favorite. I own another company and a bunch of Flight1 products and I find myself in the C130 for almost all of my flights now. Hopefully I will have some engine sounds soon.
