Beep was present only with '109/81/55 ms'. Now I'm even more confused... Without the patches that you have reverted, the ramp delay does not matter after the playback. It just cuts the VMID and that's it. On startup the ramp is initiated. If you set the ramp delay longer, than it is possible that the beginning of the audio is played already when the VMID is ramping up. So with the ramp (down) delay - the patches that you have reverted - the 'tuck' was worst after playback, than without the proper ramp (down) delay handling? I can see on the scope, that the ramp up also has kind of 'tuck' problem, but it comes when the VMID is quite low, so it is harder to hear it. By making the ramp delay longer, this 'tuck' happens when the VMID is close to 0, so it makes it less audible. -- Péter _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
