You can try using an external winemp3.acm... It should be unneeded though. $ mkdir tmp && cd tmp $ wget 'http://www.studiodust.com/misc_dl/fraunhoffer_codec_b64.zip' $ unzip -LL fraunhoffer_codec_b64.zip -d . $ cabextract -L l3codecx.exe $ mv l3codecx.acm "$WINEPREFIX"/drive_c/windows/system32/winemp3.acm
