Larry, your message didn't go through right. You might need to check your email configuration. We had to click through to an attachment, http://www.winehq.org/pipermail/wine-users/attachments/20080228/f9653c39/attachment.eml to read it. For those who are loathe to click through, here's what Larry wrote: "I have a Ham Radio program, named CQ100, it works fine using WINDOZE, but when I installed the same program on my linux system, everything works except there is no-audio, I'am using Ubuntu 7.10 linux... The author told me that windoze uses GSM 6.10 codec, plus ACM audio compression manager, which are built-into windoze... So by anychance does anyone know how to have wine use this codec, & audio compression on a Linux system...???" Larry, I think Wine can handle codecs, but you have to go out and find them and install them in wine yourself. I looked around a bit, and I found one at http://www.free-codecs.com/download/ACE_Mega_CoDecS_Pack.htm but I can't recommend that, since it looks like it's a great big copyright violation. http://ubuntuforums.org/showthread.php?t=686256&highlight=ventrilo might be useful, too; I haven't looked. There's an open source implementation, e.g. at http://kbs.cs.tu-berlin.de/~jutta/toast.html, but I don't think that's wrapped up into a Windows codec yet. (Somebody correct me if I'm wrong.) - Dan
