--- Comment #26 from rtentser@yandex.ru --- Manjaro, prebuild wine 7.16 from repos. Doesn't work out of box with error message:
026c:err:winediag:wma_decoder_create GStreamer doesn't support WMA decoding, please install appropriate plugins
It worked only after i've build and installed lib32-gst-libav from AUR. Thanks for pointing to root of the problem!
