[SOLVED] Badly distorted audio with FLV?

If these really are the only settings under Options>>Preferences>>Audio, then we're not talking about BS.Player! Also BS.Player has no setting "Don't use Vorbis codec" (though it has a setting "Use internal Vorbis decoder"). So, could you please try to be more precise?
If sound is distorted and over-amped you could have a look at the settings of BS.Player's equalizer (pre-amp) and or any filter(s) or plugin(s) used by BS.Player.
I suppose you know how to activate equalizer window. I also suppose you know if you have any plugins installed and how to access their settings, so I leave it at that.
With respect to the (audio)filters actually used by BS.Player upon playback of specific files, this may differ depending on the type of file played and on the codecs/filters which BS.Player finds installed on your system.
Therefore, when playing such flv-files, could you please check what filters/codecs are indicated under
rightclick > Options > Filters > Advanced?
When doing so please make sure to also click on the small [+]-signs in front of the filters/codecs shown.
This will reveal further information and access, so you should also be able to alter the audiofilter's settings there.
