There is a distorted audio on some files using naightly builds. Here is what GSpot says about these files:
Codec: 0x0055 MPEG-1 Layer 3 CBR
Info: 48000Hz 128 kb/s tot , Two Mono Channels
Codec: 0x0055 MPEG-1 Layer 3 CBR
Info: 48000Hz 80 kb/s tot , Two Mono Channels
Codec: 0x0055 MPEG-1 Layer 3 CBR
Info: 48000Hz 192 kb/s tot , Two Mono Channels
There are no problems with audio playback if I play the same files in VLC 0.8.6h. I have uploaded an example of problematic file at http://www.nncron.ru/temp/test.7z (compressed with 7-zip archiever, ~25M).
Here is what I see in Messages:
