--- Comment #3 from belgix_oz@hotmail.com --- (In reply to belgix_oz from comment #2) It's kind a bit a non sense if gstreamer is know required as WAVE files are properly handled by wine-staging ALSA backend (winealsa.drv) for all versions (including the latest 4.21). I never compiled wine-staging with gstreamer (neither pulseaudio) support.
What is broken since 4.17 is the link between ALSA wine-staging backend and mpg123 which on my system are compiled 32 and 64-bit. That would means (if not fixed) ALSA backend is no longer fully supported by wine.
