The DACDAT signal looks pretty good. However, I did notice something very odd. The BCLK is dead on for whatever bitrate I'm doing. However, the FRAME always runs at 44.1 kHz, no matter what I do. From my understanding of I2S (which could be wrong), I would expect FRAME to run at the sample rate I'm playing back. So if I'm playing back at 11025, I would expect BCLK to run at 352 kHz and FRAME to run at 11 kHz. I see BCLK running at 352 kHz, check. But frame is running at 44.1 kHz. This doesn't seem right. Am I missing something here? --- Geoffrey _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
