Hmm..S20_3LE right-aligns 20 bits in a 24-bit slot? I thought they're left aligned... If this is the case...shouldn't we have the same lower-volume problem for all hardwares that support S20_3LE now? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
