I am using the latest downloadable version of Parallels for Windows (2.2 build 2112). I cannot get audio to work in OS/2 no matter what I do. I am currently using OS/2 4.0 with Fixpak 15 which brings the system version up to 4.52, Revision 14.062. (Before I applied the Fixpak audio didn't work either.) I followed the instructions on the Parallels Tools CD. The ALC1$ device driver loads without errors and it even shows up in System Setup -> Hardware Manager. However, none of the multimedia utilities can play any sound. It's almost like the ALC.SYS driver is the wrong type of driver. It shows up as a Codec when I run MINSTALL. Everything else works fine -- video, network, mouse, etc. I am also using a trial key for Parallels, but I don't think that affects anything.
