[MPlayer-users] No sound when playing wma9spdmo (Windows Media Audio 9 Speech DMO) streams

[Václav Dvorák]

Hello,

I have problems with listening to asf streams (radio stations) with wma9spdmo codec. These are only stations of SPEECH type (news, spoken stories) and encoded with bitrates 8kbps or 16kbps. The same station with 32kbps stream is ok. 

The stream is normally played, but NO SOUND goes out from the audio card. The silence is sometimes breaked with a short passage of normal sound (for 5-10s), sometimes the normal sound gets ok after several minutes of silence.


Here is the mplayer output:
