[linux-audio-user] No sound from streaming audio + ALSA

Hi, I recently switched from OSS to ALSA and no sound comes from streaming audio. CD playing with xmms or cdplay works correctly. Streaming audio with xmms or gxine produces no sound. I can see that the server was contacted and the player is reproducing the stream, but only a hissing sound comes from the loudspeakers. I ruled out mixer problems because CD playing produces sound. I'm running Debian sid, kernel 2.6.14-2-686, on a Fujitsu E342 laptop, with onboard ES1879-chip Soundblaster-compatible soundcard. I've attached the output of the http://alsa.opensrc.org//aadebug.txt script. I'm really puzzled why CD playing produces sound but streaming audio doesn't. I googled on 'alsa streaming audio sound linux' and was surprised that nobody seemed to have bumped into this. Could anybody give me any leads on how to pursue this problem further ? Thanks for your attention, Paulo
