G'day Darren, What is supposed to happen is that the application that is playing the audio should set the sound card to the sample rate of the audio source. It does this by issuing commands to the sound card driver, or sound server. If the sound card is forced to another rate, then sure, you'll get pitch and speed changes. There isn't really a "system" rate, per se. Probably need more information ... are you using ALSA or OSS drivers for the sound card, and are you using an audio sound server like Jack, Esound, Pulseaudio? -- James Cameron mailto:quozl@xxxxxxxxxxxxx http://quozl.netrek.org/ _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
