Bug ID: 48230
           Summary: TES IV: Oblivion MP3 no longer play since wine-staging
                    4.17
           Product: Wine-staging
           Version: 4.21
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

Some recent changes in QUARTZ.DLL code prevent TES IV: Oblivion to play MP3
files. Other sounds like voices and ambiance sound just play fine with any 4.x
version.

The issue is present in wine-staging 4.17, 4.18, 4.19, 4.20 and the latest
4.21.

A workaround to get thing working is to override QUARTZ.DLL and QUARTZ.DLL.SO
files in /usr/lib (and optionally /usr/lib64 but Oblivion is a 32-bit game)
using files compiled for wine-staging 4.16. Workaround tested on wine-staging
4.21 only.

Using native Windows QUARTZ.DLL (32-bit) doesn't help too. For that case, game
stability is good but no MP3 sound played.
