Hallo, I have rather strange problem. There is HP 6735b laptop with integrated audio - Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) but IMHO sound chip isn't relevant at all. OS: Ubuntustudio 9.04 I can hear sound playback through headphones' output but no sound from built-in speakers (with headphones disconnected). Alsamixer shows all playback levels high and unmuted. Win Vista (dual boot) playbacks audio through laptops speaker easely. Any hints are very appreciated Antanas Budriūnas _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
