No. It is probably because the sampling rate of the sound card isn't very exact. streamer assumes the sound card samples *exactly* the sampling rate reported by the driver. If this isn't the case you'll get a drift between audio and video. streamer doesn't attempt to fix this somehow. Gerd -- You can't please everybody.
