Ok, I think I fixed some issues there, but I'm still having problems. I think part of the problem is that I'm telling ALSA that I only support these sample rates: 192000, 96000, 64000, 48000, 32000, and 16000. For playback, I'm using alsaplayer to play an MP3. Could it be that alsaplayer is picking a sample rate like 44100 and since it doesn't find a match, it's failing? I thought ALSA always did sample rate conversion. Is that not true? -- Timur Tabi Linux Kernel Developer @ Freescale _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
