RE: libwma generates lower output volume than libavcodec

> Decoding WMA streams (e.g. Codec: wmav2, Bitrate: 128kbps, Sample rate: 44.1KHz, Channels: 2) with libwma on mplayer causes the output volume to be lower than with libavcodec, but libavcodec has a high cpu usage on the ARM processor I'm using (it has no hardware support for floating-point arithmetic).

Testing my 128k files, I get identical output level compared to the Microsoft decoder. If you have files that don't match the level of the MS decoder in rockbox, could you post one of them and the exact revision and device (or simulator) you used?
