I think you should consider using RT-Linux where you can make your realtime task run at predefined scheduling rate. Schduling rate of 1 MHz is quite high, interrupt latency and scheduling jitter is around 3 microseconds in RT-Linux, afaik. Personally I would make D-class amp's PWM control using some DSP card (with AD, TI or Motorola DSP processor). PC's CPU would only feed audio data to that card. - Jussi Laako -- PGP key fingerprint: 161D 6FED 6A92 39E2 EB5B 39DD A4DE 63EB C216 1E4B Available at PGP keyservers _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
