I guess most quality conscious products can afford to attach a dedicated OSC to a good CODEC. A CODEC already specifies the clocks it support and usually comes with 'preferred' input clocks. So, just having a specified rating accurate enough OSC can take care of quality. On the other hand the clock sources on CPU side are not particularly accurate for audio-clock generation. Or so have I seen so far. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
