--- Comment #121 from Brian bkohler36@gmail.com --- I'm sorry for the double comment but there's actually something I forgot to mention on comment #120. When trying to run the game under nouveau sound stopped working. Under the proprietary drivers it worked normally. This line of console output seems to be relevant to this issue: err:dsound:get_mmdevenum CoCreateInstance failed: 80004005
Maybe later I'll make a new prefix and install the native libraries that make sound work for PSOv2 and see what happens.
